https://docs.gitea.io/en-us/integrations/ says "If you're looking for CI/CD look at this awesome list [and good luck]": https://gitea.com/gitea/awesome-gitea#user-content-devops

As far as "Github actions are supported", I seem to recall they're using "act" for that and this issue appears to match my recollection, as well as my experience with act being fine for hello-world but 100% absolutely not a replacement for a formal CI/CD system: https://github.com/go-gitea/gitea/issues/13539#issuecomment-...

I will concede I have not tried keeping up with their fork <https://gitea.com/gitea/act> so maybe they cured all its ills
