Graylog is available in two editions. Graylog Open is the community edition: free to use, including in production, with all the essential log management features such as collection, indexing, search, dashboards, streams, pipelines, and basic alerting. The source code is available on GitHub. Graylog Operations and Graylog Security are commercial editions that offer advanced features such as anomaly detection, compliance reporting, advanced correlation, and enterprise support.

A key licensing note: In 2023-2024, Graylog changed its core licence from Apache 2.0 to the Server Side Public License (SSPL). For most users—companies running Graylog internally—this change has no practical impact. You can continue to use Graylog Open for free. The SSPL mainly affects those wishing to offer Graylog as a hosted service to third parties. If you require the Apache 2.0 licence, the last release under it was Graylog 5.0. Versions 5.1 and later use SSPL. For further details, see the official SSPL licence documentation.
