Integrations include GitHub, chat providers, Zendesk and authentication providers. Support options range from community help to email support and professional services.

Flarum is free, open-source forum software for running discussions on websites and online communities. It provides group permissions, category access controls, moderation and flagging. Administrators can adjust settings, themes, CSS and extensions, and disable unneeded features. Members can write with lightweight Markdown or WYSIWYG editors. Notifications include in-browser alerts and email digests, while extensions can provide real-time notifications. A REST API lets external scripts interact with the forum and follows JSON:API practices. The extension manager discovers and installs add-ons, most of which are open source and free. Self-hosting requires Apache or Nginx, PHP 8.3 or later, a supported database and SSH access for some maintenance. Flarum is MIT-licensed and directs support questions to its community forum. Its documentation describes version 2.0 as a release candidate, not a final stable release. The project serves communities from small hobby groups to large enterprise forums.
