About this list

Every tool here is a real open-source project you can self-host. Star counts and licences were read from the GitHub API when this page was generated — they are a snapshot, so follow the repository link for the current state and the authoritative licence text.

Licences vary: some are permissive (MIT, Apache 2.0) and some are copyleft (AGPL, GPL). If you plan to build a commercial product on top of one of these, check the licence on the repository first — that is what the licence badge on each card is for.

We are not affiliated with any of these projects. They are listed here because they are genuinely useful and genuinely free.
