It seems that most information that I can find on the subject is about a year old, so I am wondering if anyone has any up-to-date info.
forgejo (gitea fork) should have federation i heard https://forgejo.org/2023-01-10-answering-forgejo-federation-questions/
If you turn on Federation in Gitea app.ini settings then WebFinger will work. Nothing else is currently implemented.
The ActivityPub extension ForgeFed for federation between different servers is not finished yet. AFAIK Forgejo contributors work closely together with other ForgeFed devs to bring it forward.
When I look at the download page, it seems active, 1.20.1 has been uploaded 2 days ago.
BTW Thanks for the question, I was using gogs, but that development seems to have halted. I’ll try a migration to gitea.
Do you have a link to the year-old info for context? I’m curious why people would be interested in federation of a DVCS like Gitea et al?
git is distributed. but not issues, pull requests, forks… I think federation would provide all or most of that.
