Flarum

The extensible community framework

Visit Flarum

Flarum is free, open-source forum software released under the MIT License and governed by the Flarum Foundation, a Dutch non-profit that owns the project's software, name, trademarks, and assets. It is designed to support communities ranging from small hobby groups to large enterprise forums, with extensibility as a central part of the platform.

Core capabilities include groups and permissions for controlling member access across categories, built-in moderation and flagging, admin-based styling and theme installation, and custom CSS. The editor supports both lightweight Markdown and full WYSIWYG modes. Engagement features include in-browser notifications, email digests, and real-time websocket extensions. Flarum is built on Laravel and is extensible through an API and a large ecosystem of community-built extensions, which can be installed or developed for a specific forum.

Flarum is intended for community administrators, developers, and contributors who want a self-hosted, customizable discussion platform. It is distributed as free, open-source software under the MIT License, with no paid editions, trials, or seat-based or usage-based pricing described.
