Grafana is a multi-platform open source analytics and interactive visualization web application. It can produce charts, graphs, and alerts for the web when connected to supported data sources.

There is also a licensed Grafana Enterprise version with additional capabilities, which is sold as a self-hosted installation or through an account on the Grafana Labs cloud service. It is expandable through a plug-in system. Complex monitoring dashboards can be built by end users, with the aid of interactive query builders. The product is divided into a front end and back end, written in TypeScript and Go, respectively.

As a visualization tool, Grafana can be used as a component in monitoring stacks, often in combination with time series databases such as InfluxDB, Prometheus and Graphite; monitoring platforms such as Sensu, Icinga, Checkmk, Zabbix, Netdata, and PRTG; SIEMs such as Elasticsearch, OpenSearch, and Splunk; and other data sources. The Grafana user interface was originally based on version 3 of Kibana.

Grafana was first released in 2014 by Torkel Ödegaard as an offshoot of a project at Orbitz. It targeted time series databases such as InfluxDB, OpenTSDB, and Prometheus, but evolved to support relational databases such as MySQL/MariaDB, PostgreSQL and Microsoft SQL Server.

In 2019, Grafana Labs secured $24 million in Series A funding. In the 2020 Series B funding round it obtained $50 million. In the 2021 Labs Series C funding round, Grafana secured $220 million.

Grafana Labs acquired Kausal in 2018, k6 and Amixr in 2021, and Asserts.ai in 2023.

Grafana is used in Wikimedia's infrastructure. In 2017, Grafana had over 1000 paying customers, including Bloomberg, JP Morgan Chase, and eBay.

Previously, Grafana was licensed with an Apache License 2.0 license and used a CLA based on the Harmony Contributor Agreement.
