A web browser is an application that allows you to access and view websites and other content on the internet. Different browsers have their own strengths, focusing on speed, privacy, or customizability, and can be used on various devices, including desktops, laptops, and mobile phones.

This is a comparison of both historical and current web browsers based on developer, engine, platform(s), releases, license, and cost.

Basic general information about the browsers. Browsers listed on a light purple background are discontinued. Platforms with a yellow background have limited support.

Browsers are compiled to run on certain operating systems, without emulation.

This list is not exhaustive, but rather reflects the most common OSes today (e.g. Netscape Navigator was also developed for OS/2 at a time when macOS 10 did not exist) but does not include the growing appliance segment (for example, the Opera web browser has gained a leading role for use in mobile phones, smartphones, the Nintendo DS and Wii, and Personal Digital Assistants, and is also used in some smart TVs). Both the web browser and OS means most recent version, example: Windows 11 with Internet Explorer 11.
