I use Forgejo for personal projects but wanted a managed CI with higher compute. Cirrus CI[0] only supports GitHub, so I built a small bridge that listens to Forgejo webhooks, triggers Cirrus builds, and syncs commit status back.

Repo: https://codeberg.org/chenghui-lee/forrus

Public instance: https://forrus.lchenghui.com/

It currently supports:

- push + PR builds based on .cirrus.yml file

- automatic polling for build status

- status reporting back to Forgejo/Gitea

Limitations:

- doesn't support Cirrus CI's `changes_include`

- Starlark is not supported (yet)

Happy to answer any questions!
