Run it yourself
KeyCloak’s README does not show a docker run, docker compose up or helm install in a code block, so this page will not guess one. It may be a desktop app, a library, or documented on its website.

Where this page comes from
- Stars, licence, activity, issues, releases and the self-host command are read from the repository. 2026-10-19
- The pairing with Auth0 and the category come from opensourcealternative.to, a community directory of open-source alternatives. We re-read it weekly.
- Star momentum comes from our own daily readings of the repository. How we collect data
