Flarum
A self-hosted Communication & Social app you can run on your own server.
Flarum is an open, self-hosted communication platform — you install it on your own hardware and keep full control of your data. Self-hosting it means no per-user subscription and no third-party cloud holding your information.
Development happens in the open on GitHub; the repository has collected 16.4K stars so far. Repository activity was last recorded on Aug 27, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Communication tools only work if your people can reach them. Check guest access, mobile apps, and federation or bridging support before migrating a community. Self-hosting gives you the data and the rules, but someone has to own updates and moderation.
Like every project listed on SelfHosted, Flarum is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
