Sorry to ask but... Do you have any idea how git works???
Yea or use another provider like codeberg
True but switching is not that easy when all your ci pipelines and integration on in GitHub.
I don't think it's 100% compatible, but Gitea's/Forgejo's (which Codeberg runs on) own Action implementation is pretty much the same as GitHub Actions, with minor differences.
Good to know might actually try it for one project 1 st before switching
Personally I'd never use codeberg. Their FAQ on licensing [0] is basically everything that anyone who supports free software should abhor - it's "we might allow you to do what you want to".
