Minecraft server
View on WikipediaA Minecraft server is a player- or business-owned multiplayer game server for the 2011 Mojang Studios video game Minecraft. In this context, the term "server" often refers to a network of connected servers, rather than a single machine.[1] Players can start their own server either by setting one up on a computer using software provided by Mojang, or by using a hosting provider so they can have their server run on dedicated machines with guaranteed uptime.[2] The largest server is widely accepted to be the minigame server Hypixel, and previously, Mineplex.[3][4]
Minecraft multiplayer servers are controlled by server operators, who have access to server commands such as setting the time of day, teleporting players, setting the world spawn, and changing players' gamemode. The server owner (or users that have access to the live server files) can also set up and install plugins to change the mechanics of the server, and can also set up restrictions concerning which usernames or IP addresses are allowed or disallowed to enter the game server.[2]
Multiplayer servers have a wide range of activities: with some servers having unique premises, rules, and customs. Player versus player (PvP) combat can be enabled to allow fighting between players. Custom mods and plugins (server side mods) can be used with modified servers to allow actions that are not normally possible in the vanilla form of the game.[5] There also exists a modification of the server software that can allow crossplay between the Java and Bedrock editions of the game.[6]
History
[edit]Pre-release
[edit]Multiplayer was first added to Minecraft on May 31, 2009, in update 0.15 during the Classic phase of the game.[7] The first server mods quickly began to arise around this time.[8]
On September 3, 2010, work began on hMod, a notable mod which implemented an API for plugins which ensured they would remain compatible with each other provided they were using hMod. Several notable projects were created around this time for hMod, such as WorldEdit, some of which remains maintained for more modern platforms to this day.[9]
Multiplayer for Minecraft's survival mode was released on August 4, 2010.[9] The oldest server map is called "Freedonia", on the Minecraft server MinecraftOnline. The server and map were created within the first hour of Minecraft survival-mode multiplayer being released.[10]
Following stagnation in the development of hMod, a spiritual successor called Bukkit would be created by a group of hMod developers: Nathan 'Dinnerbone' Adams, Erik 'Grum' Broes, Warren 'EvilSeph' Loo, Nathan 'Tahg' Gilbert, and sk89q. The project would begin work on December 21, 2010, and officially release in 2011. The project consisted of Bukkit, licensed under GPL, and CraftBukkit, licensed under LGPL. Notably, the licensing was not legally permissible due to the inclusion of proprietary code from Mojang.[8][9]
On January 9, 2011, the first Minecraft server proxy, CraftProxy, would be created. It was a very basic proxy which primarily served to allow multiple servers to be run on the same computer with different ports.[9]
Post-release
[edit]In December 2011, Mojang and the founding Bukkit team would meet at Mojang's headquarters to discuss the potential of an official Minecraft modding API. On February 28, 2012, Mojang and Bukkit jointly announced that all founding members of the Bukkit project would be joining Mojang as employees to work on an official modding API (except for sk89q, who had left the project in early 2011). This would never be released, though the hired developers did make significant technical contributions in other ways.[8][9][11][12]
In May 2012, a server implementation called CraftBukkit− would be created by a team including developer md_5. The name was a parody of its upstream project, the recently defunct fork of CraftBukkit called CraftBukkit++. The implementation would be rebranded to Spigot on January 15, 2013, as the project grew in size.[9]
In August 2012, work began on a series of Minecraft server proxies by md_5 and Codename_B which were capable of facilitating the transfer of players between different servers connected to the proxy. This eventually culminated in a layer-7 proxy known as BungeeCord, which began development on October 4, 2012.[9]
In 2013, Mojang announced Minecraft Realms, a server hosting service intended to enable players to run server multiplayer games easily and safely without having to set up their own.[13][14] Unlike a standard server, only invited players can join Realms servers, and these servers do not use IP addresses. Since 2016, Realms have enabled Minecraft to support cross-platform play between Windows 10, iOS, and Android platforms.[15] It is a subscription-based service,[16] allowing for either three or eleven players in the realm at once depending on the subscription tier.[17] While Realms can also be purchased on the Java edition of the game, it does not enable cross platform play with Bedrock players.[18]
On 14 June 2014, Mojang began enforcing the EULA of Minecraft: Java Edition to prevent servers from selling pay-to-win items in microtransactions, which many players thought unfairly affected gameplay.[19][20] After this change, servers were only allowed to sell cosmetic items.[21] Many servers closed shortly afterwards.[22]
On June 23, 2014, the Paper project (originally PaperSpigot) would be launched by Z750 and gsand as a fork of Spigot following increased reluctance of Spigot to accept community contributions. The project would see many improvements in performance compared to Spigot.[9] As of June 2025, the community-ran metrics platform bStats tracks an all-time record of over 130,000 Paper servers running concurrently, taking up over 60% of all server implementations stemming from the Bukkit ecosystem.[23][24]
On August 24, 2014, EvilSeph would announce the discontinuation of the Bukkit project citing the legal grey area of the project as well as Mojang's new enforcement of the EULA.[25] This would then be rebutted by Mojang employees over Twitter, who stated that the Bukkit Team had transferred their rights to the project to Mojang as part of their employment for the company. Developers Dinnerbone and Grum stated they would update Bukkit to the next version of Minecraft themselves, clarifying that Bukkit still was not going to be an official modding API.[9] On September 5, 2014, a prominent Bukkit contributor identified as Wolvereness sent a DMCA takedown notice to GitHub to remove all of their contributions to Bukkit and its forks (including Spigot) due to copyright infringement caused by the inclusion of proprietary Mojang code in Bukkit.[26] The project never received another update, effectively shutting it down.[8][9]
Spigot would return with an updated version on November 28, 2014, following migration of code from GitHub to a self-hosted Stash server, the introduction of a Contributor License Agreement, and the development of build tooling designed to evade the DMCA takedown by providing build tools which added patches to a copy of Bukkit before the takedown instead of distributing pre-compiled binaries. This led to Spigot becoming the de facto successor to Bukkit.[9][27]
On September 20, 2017, the "Better Together Update" was released for Bedrock codebase-derived editions of the game, which added cross platform multiplayer support, along with four featured servers: Lifeboat, Mineplex, InPVP and CubeCraft.[28]
On July 27, 2022, player chat reporting was added as a part of "The Wild Update", 1.19.1. This allowed players to report abusive chat messages sent by other players directly to Mojang, and players could be banned from playing on multiplayer servers, including realms, as a whole for violating Microsoft's community standards.[29]
On November 7, 2023, Mojang Studios, in partnership with GamerSafer, opened the official server list of Minecraft. Servers listed on the site can earn badges showing, for example, their commitment to safety and community management features, which are designed to give parents an indication of which servers offer the highest standards.[30]
Management
[edit]Managing a Minecraft server can be a full-time job for many server owners. Several large servers employ a staff of developers, managers, and artists.[22] Running a large server can be expensive for its operators,[31] particularly those that have more than a thousand players. Expenses may include salaries, hardware, bandwidth, and DDoS protection.[32] Dunbar stated that MCGamer, which has had over 50,000 daily players, has expenses that can be "well into the five-figure marks" per month. As of 2015, expenses of Hypixel, the largest server, are nearly $100,000 per month.[32] Many servers sell in-game ranks, cosmetics and passes to certain minigames or gamemodes to cover expenses.[22][19]
Technical aspects
[edit]For the Java edition, Mojang release an official JAR file for server operators to run their servers with each game update. Third party server JARs also exist; typically utilizing resources more efficiently than the official server software and allowing the use of plugins.[33] However, Minecraft servers have traditionally been restricted to running most operations on a single core (main thread) with a limited amount of other operations being able to be run asynchronously, making them inefficient for large player counts.[34]
Minecraft: Java Edition uses the default port 25565 to listen to and accept new connections.[35]
Notable servers
[edit]This section needs to be updated. (November 2025) |
The most popular server on Minecraft Java Edition is Hypixel, which was released in April 2013 and has hosted tens of millions of unique players, making it one of the largest and most influential community-run servers in the game’s history.[36][37]
By the mid-2020s, Hypixel’s founder reported that the server had surpassed 38 million lifetime unique players, while continuing to maintain some of the highest concurrent player counts in Minecraft multiplayer.[38]
Another major network is CubeCraft Games, launched in December 2012 on Java Edition and expanded to Bedrock Edition in 2018. CubeCraft has reported over 30 million unique server connections and peak concurrent player counts exceeding 57,000, making it one of the most active cross-platform Minecraft networks.[39]
Other notable servers include MCGamer released in April 2012, which has reported more than 3.5 million unique players;[40] Wynncraft, an MMORPG-style server released in April 2013 that features a persistent open world and quest-based gameplay and has surpassed one million unique players;[41] and Emenbee, launched in 2011, which has also exceeded one million unique players over its lifetime.[42]
Some large multiplayer networks have undergone significant changes in recent years. Mineplex, once one of the largest Minecraft servers by concurrent player count, officially shut down in May 2023 following a sustained decline in activity, marking the closure of one of the game’s earliest major server networks.[43]
According to Polygon, by 2014, servers such as Mineplex, Hypixel, Shotbow, and The Hive were each receiving well over one million unique players per month, highlighting the scale and popularity of large multiplayer Minecraft networks.[44]

Origins in early Minecraft development
Multiplayer functionality was first introduced in Minecraft Classic version 0.0.15a (Multiplayer Test 1) on May 31, 2009, enabling basic creative-mode connections limited to local area networks (LAN) or manual port forwarding for external access.) These early implementations relied on rudimentary server software run directly from the client, with players hosting sessions on personal computers lacking dedicated server executables, often resulting in frequent disconnections, desynchronization of block changes, and vulnerability to exploits due to absent authentication mechanisms.[11] Survival multiplayer arrived with Alpha v1.0.15 on August 4, 2010, marking the release of the first dedicated Alpha server software (version 0.1.0), which supported persistent worlds and player interactions in a resource-gathering environment.[12] Hosting remained grassroots, with individuals configuring routers for port 25565 forwarding to expose home-based servers to the internet, confronting hardware limitations like insufficient RAM causing entity overloads and no built-in tools for moderation or logging.[13] This era emphasized community-driven experimentation, as players shared IP addresses on forums to form ad-hoc groups without centralized directories. Public servers began proliferating around mid-2010, exemplified by MinecraftOnline's launch in August 2010, whose Freedonia world holds the oldest truly public map among SMP servers, as one of the earliest persistent survival instances open to contributors.[14][15] Beta 1.8, released September 17, 2010, enhanced accessibility by adding a multiplayer menu with a server list for saving and sorting previously joined addresses by ping and player count, reducing reliance on external announcements while still demanding manual IP entry for discovery.[16] These developments fostered initial community hubs amid ongoing instability, setting the stage for broader adoption before structured modding frameworks emerged.Expansion through modding and plugins
The release of Bukkit in December 2010 marked a turning point for Minecraft server customization, providing an open-source API that enabled developers to create server-side plugins without requiring client modifications.[17] This allowed administrators to implement features such as granular user permissions via plugins like PermissionsEx, virtual economies with Essentials, and structured minigames, extending vanilla servers' capabilities for multiplayer interactions.[18] By supporting modifications solely on the server end, Bukkit facilitated scalable, community-hosted environments that could handle permissions systems, anti-griefing tools like WorldGuard, and custom events, diverging from rudimentary hosting toward programmable extensibility.[19] Growth accelerated following Minecraft's Beta 1.8 update on September 14, 2011, which introduced The End dimension, and the full release of version 1.0 on November 18, 2011, as these milestones provided fresh content ripe for plugin integration.[20] Bukkit's CraftBukkit implementation, which bridged the API to the core server code, saw widespread adoption, enabling diverse gameplay modes like survival competitions and economy-driven worlds that attracted larger player communities.[21] This era's innovations scaled servers beyond vanilla limits, with plugins fostering persistent worlds, land claiming, and multiplayer arenas that emphasized causal gameplay enhancements grounded in server logic rather than client hacks. Spigot, an optimized fork of CraftBukkit released around 2012, further propelled expansion by incorporating performance tweaks for higher player concurrency and reduced latency, making it suitable for enterprise-scale operations.[22] Servers like Hypixel, founded on April 13, 2013, exemplified this shift, leveraging Spigot to host minigames such as SkyWars and Bed Wars for millions of users, achieving efficiencies unattainable in unmodified setups.[23] Community-driven plugin ecosystems, hosted on platforms like BukkitDev from late 2011, democratized development, resulting in thousands of extensions that prioritized empirical server stability and resource management over cosmetic alterations.[24] This period's focus on structured API-based modding laid the foundation for servers to evolve into specialized hubs, distinct from earlier ad-hoc modifications.Modern era and adaptation to updates
Following Microsoft's acquisition of Mojang on September 15, 2014, Minecraft server operators faced significant regulatory adjustments through clarifications to the End User License Agreement (EULA) in late 2014 and early 2015. These changes explicitly prohibited pay-to-win mechanics, where in-game advantages such as powerful items or ranks were sold for real money, requiring servers to shift toward cosmetic or non-competitive monetization models by August 1, 2014.[25][26][27] This enforcement, aimed at preserving gameplay fairness, led to widespread store overhauls and temporary shutdowns among popular servers, though compliance ultimately stabilized the ecosystem by curbing exploitative practices that had proliferated in prior years.[27] Major game updates from 2018 onward necessitated technical adaptations in server software to handle protocol revisions, new world generation, and performance demands. The 1.13 Aquatic Update, released on July 18, 2018, introduced extensive ocean biomes and block registry changes, prompting server forks to implement compatibility patches and optimizations for increased entity loads.[28] Similarly, the 1.18 Caves & Cliffs Update on November 30, 2021, expanded world height from 256 to 384 blocks and overhauled terrain generation, straining older server implementations and accelerating adoption of high-performance forks like PaperMC, which enhanced chunk loading and reduced tick lag for these features.[29] The 1.21 Tricky Trials Update, launched June 13, 2024, added trial chambers and new mob behaviors, further requiring optimizations in pathfinding and structure generation to maintain playability on populated servers.[30] PaperMC, as a Spigot derivative, has been instrumental in these transitions by incorporating asynchronous chunk loading and memory efficiencies tailored to post-1.13 architectures.[31] By 2025, Minecraft servers have grappled with declining custom server activity amid rising operational costs and shifting player preferences toward official Realms or single-player modes, even as the game sustains over 200 million monthly active users across editions.[32][33] Factors include persistent EULA constraints on monetization, high hardware demands for modern updates, and competition from cross-platform Bedrock servers, resulting in fewer independent Java Edition custom servers despite the edition's enduring modding appeal.[32] Efforts to bridge Java and Bedrock via proxies have gained traction for cross-play, but Java-focused servers continue prioritizing optimization forks to counter resource-intensive updates and sustain niche communities.[32]Technical Fundamentals
Core server software options
The official server software for Minecraft: Java Edition, known as the vanilla server JAR, is provided directly by Mojang Studios and implements the game's core mechanics without modifications, plugins, or mod support. Released alongside major updates—such as version 1.21 in June 2024—this software prioritizes fidelity to the intended gameplay but exhibits limitations in scalability for high-player-count environments due to synchronous processing and lack of optimizations.[34] It serves as the baseline for all Java Edition servers, requiring manual configuration via properties files for basic multiplayer hosting. Community forks have evolved from the Bukkit plugin ecosystem to address vanilla's performance constraints. Bukkit provided a plugin API, with CraftBukkit as its reference implementation. Spigot, originating as a high-performance derivative of CraftBukkit around 2012, incorporates asynchronous optimizations and the Bukkit API for server-side plugins, enabling features such as custom economies or anti-griefing tools without client changes. Spigot supports thousands of plugins but can introduce timing alterations that affect redstone contraptions or entity behaviors compared to vanilla. Paper, a fork of Spigot (with development beginning around 2015 and major advancements by 2019), builds on this with further enhancements like improved chunk loading, bug fixes for gameplay inconsistencies, and other optimizations, resulting in higher throughput for large servers—often handling 100+ players more efficiently—while maintaining plugin compatibility.[35][36] Paper has inspired numerous popular derivatives, including Purpur, which emphasizes extensive configurability and additional gameplay features, and Folia (developed by PaperMC), which introduces regionized multithreading to distribute workloads across multiple cores for improved scalability in high-player-count scenarios. These are Java Edition-specific, plugin-focused server software that build on the Bukkit/Spigot/Paper API ecosystem. Not all servers use these forks; official vanilla Java servers and Bedrock Dedicated Servers rely on unmodified Mojang software.[37][38] Mod loaders such as Forge and Fabric extend the vanilla codebase for client-server synchronized modifications, diverging from plugin-focused forks by prioritizing expansive content additions like new dimensions or mechanics. Forge, established in 2011, offers a mature ecosystem for complex mods but demands more computational resources and slower update cycles post-Minecraft releases due to its comprehensive API. Fabric, launched in 2018 as a lighter alternative, facilitates quicker adaptation to new versions and reduced overhead, though its mod library remains smaller than Forge's, trading breadth for agility in development.[39][40] For Minecraft: Bedrock Edition, the Bedrock Dedicated Server (BDS) is the official, free server software from Mojang for hosting multiplayer worlds on Windows or Linux. It enables true cross-platform play across mobile, console, and PC devices, with direct support from Mojang/Microsoft. BDS has lower CPU and RAM usage compared to Java Edition servers, allowing for cheaper or lighter hosting. It supports add-ons, behavior packs, resource packs, and basic customization, with simple setup ideal for small to medium groups. However, BDS lacks official plugin support or an extensive modding ecosystem (unlike Java's Spigot/Paper), has limited administrative commands, tools, and world generation options, and offers fewer options for gameplay modifications or large-scale servers. Certain Marketplace content may not function on self-hosted BDS (though available on Realms), and advanced features may require third-party alternatives like PocketMine, which have their own drawbacks.[41][42] This makes BDS suitable for vanilla-like, cross-platform experiences with moderate player counts, though it is less suited to mod-heavy or high-performance scenarios relative to Java's ecosystem.[41]| Software | Base | Primary Use Case | Key Trade-offs |
|---|---|---|---|
| Vanilla JAR | Official Java | Unmodified multiplayer | High fidelity but poor multi-player scaling without tweaks[34] |
| Spigot | Java fork | Plugin-enhanced servers | Performance gains; may alter vanilla timings[35] |
| PaperMC | Spigot fork | High-load plugin servers | Superior efficiency; inherits Spigot's potential inconsistencies[36] |
| Purpur | Paper fork | Highly configurable plugin servers | Extensive configurability and additional features; maintains Paper compatibility[37] |
| Forge | Java loader | Modded content | Vast mod support; resource-heavy, slower updates[39] |
| Fabric | Java loader | Lightweight modding | Fast updates; limited mod variety vs. Forge[40] |
| BDS | Official Bedrock | Cross-platform multiplayer | Low resource usage, official support, true cross-platform; limited extensibility, no official plugins/mods, fewer customization options[41] |
Networking protocols and hosting
Minecraft servers establish player connections primarily via the TCP protocol on the default port 25565, enabling reliable data transmission for login handshakes, world updates, and gameplay synchronization.[43][44] This port must be forwarded through routers and firewalls for external access, as inbound traffic routes directly to the server's IP address.[45] While some configurations explore UDP for supplementary features like query responses, the core client-server communication remains TCP-based to ensure ordered packet delivery and error correction.[46] Minecraft servers support additional management protocols beyond the primary gameplay connection. The server query protocol operates over UDP, typically on the server port or a configured offset, allowing external tools to retrieve status information such as the message of the day, player count, and maximum players without establishing a full client connection. Remote administration is enabled through the RCON protocol over TCP on a configurable separate port (default 25575), which authenticates users and permits execution of server commands remotely, including chat-related commands such as "say" or "tellraw" to broadcast messages in-game.[47][48][49] Despite the availability of RCON for remote command execution, Minecraft server software does not natively include a REST API for posting chat messages via HTTP. As of 2026, no public Minecraft servers are known to offer a REST API specifically for posting chat messages. Server software such as Spigot and Paper does not include this feature natively, and no widely recognized plugins or services provide a public REST endpoint for sending chat messages due to security risks like spam and abuse. Server owners can implement custom solutions using plugins, RCON wrappers that expose REST interfaces, or custom code, but no standard or public implementations are commonly available. No information exists regarding changes or additions planned for 2026. For networks spanning multiple interconnected servers—such as hubs linking survival, creative, and minigame instances—proxy software like BungeeCord facilitates seamless player transitions without requiring separate IP logins.[50] BungeeCord operates as an intermediary proxy, listening on a single external port (often 25565) and internally forwarding connections via TCP to backend servers configured in its YAML file, supporting scalability for large communities.[51] Its fork, Waterfall, aimed to enhance performance and stability but reached end-of-life in March 2024; Velocity has succeeded it as an actively developed proxy with superior speed and scalability.[52][53] Similar to server software, community forks of proxy software exist, such as FlameCord for BungeeCord (emphasizing advanced anti-bot protection and performance) and various forks of Velocity, though the primary and most widely used options remain BungeeCord, Waterfall (end-of-life in 2024), and Velocity.[54] This setup demands low-latency infrastructure to minimize transfer delays, typically achieved through dedicated proxy hosting separate from game servers. Hosting Minecraft servers involves balancing computational demands with connectivity reliability, often via self-managed virtual private servers (VPS), cloud instances, or specialized providers such as Apex Hosting, Shockbyte, BisectHosting, and Nodecraft. Economical options for basic plans with 1-2 GB of RAM have historically started from approximately 2-5 € per month, based on data through 2024-2025. Specific prices for 2026 are not fixed and depend on current and future promotions; for updated pricing and any discounts, consult the providers' websites directly.[55][56][57][58] For accommodating 50 or more concurrent players on vanilla or lightly modded setups, allocations of 6-8 GB RAM suffice to manage entity loading and chunk generation, though plugin-heavy environments may require 10-16 GB to prevent garbage collection pauses.[59] CPU selection prioritizes high single-thread clock speeds (e.g., 3.5 GHz or above) over core count, as the server's 20-tick-per-second loop processes updates sequentially.[60] Community discussions on Reddit, primarily in subreddits r/admincraft, r/feedthebeast, and r/HomeServer, indicate that RAM speed has minimal or no significant impact on Minecraft server performance, including for modded servers. Users emphasize that RAM capacity (amount) is far more important than speed, with CPU single-thread performance being the primary bottleneck. Faster RAM is generally not worth prioritizing over higher capacity or better CPU.[61][62] Dedicated hosting mitigates home-based limitations such as upload bandwidth caps, which can cause desynchronization for distant players. However, Minecraft servers have relatively low bandwidth requirements compared to many other multiplayer games. A typical server for 10 players uses around 2-5 Mbps of upload bandwidth on average, depending on player activity, view distance, mods/plugins, and version (Java or Bedrock). This equates to roughly 100 MB of data per hour per player, or 1 GB per hour total for 10 active players, with peaks occurring mainly during chunk loading or periods of high activity.[63] Cross-edition interoperability, enabling Bedrock Edition clients to join Java Edition servers, relies on protocol bridges like GeyserMC, which translates disparate packet formats in real-time.[64] Initiated around 2019, GeyserMC proxies Bedrock UDP-based connections (default port 19132) into Java's TCP framework, supporting features like inventory syncing but introducing minor latency from translation overhead.[65] This facilitates broader player bases without native Mojang support for unified editions, though compatibility varies by version updates.[66]Performance and optimization techniques
While software and configuration optimizations are essential, the primary hardware bottleneck for Minecraft servers is CPU single-thread performance, with RAM capacity being more critical than RAM speed, aligning with community experiences in modded and high-load environments.[67][68] Optimizing Minecraft server performance focuses on maintaining ticks per second (TPS) close to the ideal 20 TPS by reducing computational overhead from world generation, entity processing, and tick updates. Key techniques target runtime efficiency through configuration adjustments, JVM tuning, and auxiliary tools, distinct from network latency issues. These methods are particularly crucial for servers hosting multiple players or complex builds, where unoptimized setups can lead to rubber-banding or entity despawn failures.[31] In theserver.properties file, parameters like view-distance control the number of chunks rendered around players, with the default of 10 often straining resources; lowering it to 6-8 can yield 20-30% TPS improvements on populated servers by decreasing loaded chunks exponentially. Similarly, simulation-distance governs entity ticking and mob spawning ranges, recommended at 3-6 to limit active simulations without fully disabling mechanics, ensuring entities outside this radius do not consume tick cycles. Chunk loading optimizations include setting mob-spawn-range below 20 to concentrate spawns and reduce global entity loads, which indirectly caps farm outputs in technical setups.[69][70][31]
JVM tuning via Aikar's flags enhances garbage collection for Minecraft's Java-based servers, using G1GC parameters like -XX:+UseG1GC -XX:MaxGCPauseMillis=200 to minimize pause times and stabilize TPS under memory pressure; these were developed specifically for Minecraft to prevent spikes from heap fragmentation. For world-scale efficiency, plugins like Chunky enable pre-generation of chunks within a defined radius or world border, offloading initial terrain computation to reduce stutter during player exploration—generating up to thousands of chunks in advance can eliminate lag spikes from on-demand loading.[71][72][73]
In technical servers featuring redstone contraptions or mob farms, optimizations mitigate tick-intensive behaviors: limit redstone clock frequencies to avoid rapid signal propagation that overwhelms the update loop, and configure mob caps via max-entities or spawn limits to prevent overpopulation from farms exceeding simulation distances. Paper server software incorporates redstone timing fixes and entity culling that preserve vanilla functionality while boosting TPS by reducing redundant calculations, outperforming vanilla in high-load scenarios through asynchronous chunk handling and optimized pathfinding.[74][75][76]
Server Variants
Vanilla and semi-vanilla implementations
Vanilla Minecraft servers employ the unmodified official server software distributed by Mojang Studios, downloadable directly from the Minecraft website since the game's early multiplayer releases.[34] This setup executes the core Java Edition executable without plugins, mods, or external alterations, ensuring gameplay adheres strictly to Mojang's intended mechanics for survival, crafting, and world generation.[77] Administrators configure such servers via theserver.properties file for basic parameters like difficulty and whitelist status, but no code injections occur, limiting extensibility to vanilla commands and redstone logic.[47] These servers prioritize an authentic experience, where emergent gameplay arises solely from player interactions with procedural worlds, fostering organic challenges like resource scarcity and mob threats unmitigated by custom safeguards.
Semi-vanilla servers extend this foundation with lightweight, native-compatible additions, primarily datapacks introduced in Minecraft 1.13 on July 18, 2018, which modify elements such as loot tables, recipes, and advancements without requiring mod loaders. Datapacks integrate via the datapacks folder in world directories, enabling quality-of-life tweaks like one-player sleeping to bypass unanimous sleep requirements or doubled shulker shell drops to reduce grind without altering balance fundamentals.[78] Popular collections from sources like Vanilla Tweaks provide modular options, such as armor stand limitations for cleaner builds or custom nether portal mechanics, maintaining compatibility across updates while avoiding plugin dependencies that could introduce latency or version conflicts.[78] This approach contrasts with heavier variants by eschewing economy systems or teleports, preserving causal progression where player effort directly influences outcomes.
Prominent examples include community-driven servers like Hermitcraft, established in 2012, which operate in a semi-vanilla mode emphasizing collaborative mega-builds and technical redstone projects using select datapacks for usability without economy plugins or grief prevention beyond manual moderation.[79] Such setups, often termed "French vanilla" in player discussions, incorporate enhancements like microblocks or AFK displays to support long-term creativity among whitelisted members, yet retain vanilla's core unpredictability, including natural world borders and update-induced resets.[79] By design, these implementations appeal to players seeking unadulterated multiplayer survival, where authenticity derives from Mojang's procedural algorithms rather than developer-imposed features.[80]
Plugin-enhanced servers
Plugin-enhanced servers employ software like Spigot, a modified version of CraftBukkit that builds on the Bukkit API to deliver optimized, server-side extensions without altering client software. This approach enables administrators to add functionalities such as custom commands, economy systems, and rule enforcement while preserving compatibility with unmodified vanilla clients. The Bukkit API, launched in December 2011, established the framework for plugin development by exposing server events and components for programmatic access, leading to an extensive library of add-ons that enhanced multiplayer experiences across thousands of servers.[81][82][17] However, core server software such as Spigot and Paper does not include a native REST API specifically for posting chat messages, and no widely recognized plugins provide a public REST endpoint for this purpose. This absence stems primarily from security risks, including the potential for spam, abuse, and unauthorized access to in-game communication. Server owners may implement custom solutions using custom plugins, RCON wrappers with REST interfaces, or other bespoke code. As of 2026, no information exists regarding planned changes or additions to introduce native support for such a feature. Essential plugins in this ecosystem include EssentialsX, which provides core utilities like teleportation (/tp), warps, and player moderation tools; LuckPerms, a robust permissions system supporting group hierarchies, inheritance, and cross-server synchronization; and WorldEdit, a toolset for efficient terrain manipulation, schematic copying, and region selection via commands like //wand and //set. These server-side additions facilitate administrative control, such as defining protected areas or assigning ranks, without the overhead of full mod installations.[83][84][85] Such servers prevail in minigame hubs, where plugin APIs underpin competitive modes including capture-the-flag variants and point-domination games, allowing seamless integration of arenas, matchmaking, and score tracking. Spigot's performance tweaks, including over 150 optimizations beyond CraftBukkit, support high-player-count environments typical of these setups.[86][87] A key drawback involves update compatibility: Minecraft's major releases, like version 1.19 in June 2022, frequently alter underlying net.minecraft.server (NMS) packages and protocols, necessitating plugin recompilation or API adaptations to avoid crashes or feature breakage. Developers must often rewrite dependencies on obfuscated internals, with delays common until community patches emerge, as seen in widespread reports of legacy plugins failing post-update without source access fixes.[88][89]Modded and custom content servers
Modded Minecraft servers utilize modloaders such as Forge and Fabric to implement transformative modifications that fundamentally alter the game's core logic, enabling features like advanced technological automation, RPG-style progression systems, and custom biomes or dimensions not possible through plugins alone.[90][91] Unlike plugin-enhanced servers, which extend vanilla functionality via server-side scripts, modded servers require clients to install identical mods for synchronization, ensuring all players experience the modified world mechanics consistently.[92] Popular modpacks, such as those from Feed The Beast (FTB) and All the Mods (ATM) series, bundle hundreds of interdependent mods into cohesive experiences; for instance, All the Mods 10 incorporates approximately 500 mods focused on quests, endgame challenges, and expansive content variety.[93][94] These packs often emphasize tech mods for machinery and resource processing or RPG elements like skill trees and narrative-driven quests, demanding precise server configuration to handle mod interactions and prevent crashes from incompatibilities.[93] Due to the computational intensity of rendering complex mod interactions, entity behaviors, and generated structures, modded servers typically require significantly more resources than vanilla or plugin-based setups, with recommendations of 6-8 GB RAM for small groups (1-10 players) on medium to heavy packs, scaling to 8-12 GB or higher for larger populations or intricate worlds.[95][96][97] Community-driven modpacks frequently adapt to Minecraft updates, integrating new vanilla features; following the 1.21 update's archaeology system introduced on June 13, 2024, packs have incorporated enhancements like expanded dig sites and relic mechanics via compatible mods, maintaining relevance through iterative releases in 2024 and 2025.[98][99]Bedrock Edition dedicated servers
The Bedrock Dedicated Server (BDS) is the official, free software distributed by Mojang Studios for self-hosting multiplayer servers in Minecraft Bedrock Edition, available for Windows (version 10.0.15063 or later) and Ubuntu Linux systems.[41][100] Unlike subscription-based services, BDS enables unlimited player access on user-managed hardware or cloud instances, supporting cross-platform connectivity across mobile, console, and PC devices without Java Edition compatibility.[41] First publicly released in version 1.6.1.0 in early 2018, with stable updates aligning to Bedrock Edition releases such as 1.11.0.23 on April 23, 2019, BDS emphasizes simplicity for small-scale hosting akin to personal Realms but with greater administrative control over properties like world generation and player limits via theserver.properties file.[101][102]
BDS provides several advantages for hosting multiplayer worlds. It is official and free software with direct support from Mojang/Microsoft. It enables true cross-platform play across all Bedrock Edition platforms, including mobile, console, and PC. It has lower CPU and RAM requirements compared to Java Edition servers, allowing for cheaper or lighter hosting on less powerful hardware or cloud instances.[42][103] It supports add-ons, behavior packs, resource packs, and basic customization through official tools. Its setup is relatively simple, making it suitable for small to medium-sized groups.
However, BDS also has notable disadvantages. It lacks official plugin support or an extensive modding ecosystem, unlike Java Edition servers using Spigot or Paper. Administrative commands, tools, and world generation options are limited. There are fewer options for gameplay modifications or support for large-scale servers. Certain Marketplace content cannot be run on self-hosted BDS, although it may be available on Realms.[104] For advanced features, operators may need to rely on third-party alternatives such as PocketMine, which introduce their own drawbacks including potential instability and incompatibility with official protocols.
To update the Bedrock Dedicated Server to the latest version, follow these steps:
- Stop the server completely to prevent data corruption.
- Create a full backup of the server directory, with particular attention to the "worlds" folder containing saved worlds and configuration files such as
server.properties,permissions.json, andallowlist.json. - Download the latest stable version of the Bedrock Dedicated Server ZIP file from the official Minecraft download page.[41]
- Extract the contents of the ZIP file to a temporary location.
- Copy all extracted files and folders (including
bedrock_server,config_examples,legal, and others) into the existing server directory, overwriting the existing files. Do not overwrite the "worlds" folder or any custom configuration files to preserve world data and server settings. - On Linux systems, grant execute permissions to the
bedrock_serverfile usingchmod +x bedrock_serverand ensure any required dependencies are installed. - Restart the server and review the server logs to verify that it loads the new version correctly.
Administration
Initial setup and configuration
The initial setup of a Minecraft Java Edition dedicated server involves downloading the official server software, with the latestserver.jar file available directly from Mojang Studios' website [34], while older versions and a comprehensive list of all versions can be obtained via https://mcversions.net/, which provides direct download links to official Mojang-hosted server.jar files.[114] This jar file must be placed in a dedicated folder on a host machine running a supported operating system, such as Windows, macOS, or Linux, with sufficient resources including at least 1 GB of allocated RAM.[1] Servers for Minecraft versions 1.21 and later require Java Runtime Environment (JRE) version 21 or higher to execute, as earlier Java versions lack compatibility with the updated bytecode and runtime features introduced in these releases.[115]
To launch the server for the first time, execute the command java -Xmx1024M -Xms1024M -jar server.jar nogui from the command line in the server directory, where -Xmx and -Xms flags set the maximum and initial heap size in megabytes, respectively; this generates essential files including eula.txt, which must be edited to set eula=true to accept the End User License Agreement before restarting.[1] Upon valid execution, the server automatically generates the initial world using the default Overworld seed and biome parameters, creating the world directory with subfolders for regions, player data, and advancements; world generation employs the game's procedural algorithms based on Perlin noise for terrain and structures.[116]
The server.properties file, created during the initial run, allows baseline configuration of server behavior without plugins or mods. Key editable properties include motd for the server list message of the day (limited to 59 characters), white-list to enable or disable player access restrictions (with white-list.json managing approved usernames), gamemode for default player mode (0=survival, 1=creative, 2=adventure, 3=spectator), difficulty for world challenge level (0=peaceful, 1=easy, 2=normal, 3=hard), and spawn-protection for radius in blocks around spawn point immune to modifications.[116] Changes require server restart to apply, and improper edits can lead to syntax errors preventing launch.[117]
For public accessibility beyond local networks, configure port forwarding on the host router to direct inbound TCP and UDP traffic on port 25565—the default server port specified in server.properties via the server-port property—to the server's local IP address, typically obtained via ipconfig (Windows) or ifconfig (Linux/macOS).[118] Tools like ngrok provide an alternative for testing without router modifications by creating a secure tunnel: install ngrok, authenticate via account token, and run ngrok tcp 25565 to expose the local port via a temporary public endpoint (e.g., tcp://0.tcp.ngrok.io:12345), which players connect to instead of the local IP.[119] This method suits initial verification but incurs bandwidth limits on free tiers and requires re-establishing tunnels on restarts.[120]
Security protocols and vulnerabilities
Since the introduction of version 1.7 in October 2013, Minecraft servers have utilized universally unique identifiers (UUIDs) for player authentication, linking each account to a persistent, Mojang-verified 128-bit value that prevents username spoofing by ensuring identity consistency across sessions regardless of name changes.[121] This system requires online mode operation, where the server queries Mojang's authentication servers to validate connections, rejecting unverified clients.[122] Offline mode, which bypasses Mojang authentication to permit cracked or unlicensed clients, introduces severe risks including unrestricted access for impersonators, exploitation of alt accounts for griefing, and exposure to malware-laden pirated versions that can compromise server integrity or steal data.[123][124] Administrators mitigate these by enforcing online mode and implementing IP whitelisting or VPN tunneling for private servers, though the former remains incompatible with non-premium accounts.[125] Distributed denial-of-service (DDoS) attacks, which flood servers with traffic to disrupt connectivity, are countered through firewall configurations that limit inbound connections to Minecraft's default port 25565 and rate-limit packets, supplemented by tools like intrusion prevention systems or proxy services such as TCPShield for Layer 4 and 7 filtering.[126][127] Hosting providers often integrate hardware firewalls or upstream mitigation, as self-hosted setups remain vulnerable without such layers.[128] Third-party plugins represent a primary vulnerability vector, with backdoors embedded in unvetted downloads enabling remote code execution, credential theft, or unauthorized operator privileges; detection requires manual code review, reliance on verified repositories like SpigotMC, and runtime scanning for suspicious behaviors such as hidden command listeners.[129][130] Historical incidents, including disguised backdoor plugins that evaded detection by mimicking legitimate updates, underscore the need for compiling plugins from source when possible and monitoring console logs for anomalies.[131] As of 2026, no public Minecraft servers or widely recognized plugins are known to offer a REST API specifically for posting chat messages, as standard server software (e.g., Spigot, Paper) does not include this feature natively. This absence is intentional, primarily due to security risks such as spam, abuse, automated attacks, and potential exploitation via unauthorized access. Server administrators requiring this capability can implement custom solutions, such as private REST wrappers around protocols like RCON or bespoke plugins, but public exposure of such endpoints is avoided to prevent exploitation.[49] Automated backups form a critical defense against data loss from exploits, with best practices involving daily incremental copies stored offsite via SFTP or cloud services to prevent single-point failures, ensuring rapid restoration without retaining vulnerable snapshots on the primary host.[129][132] Failure to patch core server software or dependencies promptly can amplify exploits, as seen in Java ecosystem vulnerabilities requiring version-specific updates to avert remote code execution.[133]Moderation tools and player management
Moderation on Minecraft servers relies on plugins and systems to enforce rules, resolve disputes, and manage player behavior through logging, punishment mechanisms, and oversight tools. CoreProtect, a widely used plugin, enables comprehensive data logging of block changes, entity interactions, and player actions, allowing administrators to inspect histories and rollback griefing or unauthorized alterations with commands like/co [rollback](/page/Rollback) for targeted reversions.[134] Ban systems such as BanManager facilitate issuing temporary or permanent bans, kicks, and mutes, often integrated with web-based appeal forms where players submit evidence for review by staff, supporting multi-server synchronization to prevent evasion via IP or UUID tracking.[135]
Staff hierarchies typically structure roles from helpers handling basic reports to moderators enforcing chat rules, senior moderators reviewing appeals, and administrators with elevated permissions for server-wide decisions, promoting accountability through promotion based on performance and training.[136] Automated chat filters, including plugins like ChatControl and ChatSentry, employ regex patterns and AI-assisted scanning to detect spam, profanity, advertisements, and toxicity in real-time, applying mutes or warnings without manual intervention while allowing configurable whitelists for context.[137]
Integration with external platforms like Discord via plugins such as DiscordSRV bridges in-game events to dedicated channels for staff notifications, enabling remote monitoring of logs, ban appeals, and player reports to streamline dispute resolution across communities.[138] In larger servers, challenges include volunteer staff burnout from high volumes of disputes—often driven by harassment comprising up to 25% of moderation actions—and inconsistent enforcement due to subjective rule interpretations, necessitating clear guidelines and delegation to mitigate overload.[139][140]
