I heard Gitea planned to do ActivityPub too, but I didn't like their application, and also I didn't like Woodpicker-CI which was very limited some years ago, I lost much time learning and trying to do the same as I do with GitLab-CI and couldn't. But, I need to try Woodpicker-CI again to see if I can do it now.

I didn't know about Forgejo, thanks to mention it, I'm sure I will try it very soon, and Woodpicker-CI. 😆
