Github fediverse alternative - iusearchlinux.fyi

I am already self-hosting a lot of things for 15+ years now, including git, but I am looking for a solution like Github that is federalized (not Gitlab or the like). I want people to be able to open issues, PRs, comment, fork or star without having to create an account on my server. Is there anything like that? I saw radicle.xyz but I am not sure if that is what I want. Basically a lightweight git+ActivityPub + web frontend is what I am looking for. I think. No CI/CD or other fancy features required.

Gitea is looking into joining ActivityPub as the core framework is called.
Is it not a big no-no to use Gitea now since the commercial takeover? From what I understand, Forgejo is the safe option and I am glad to hear from the other comments that it is getting support for that through ForgeFed!
Excuse me for being uninformed, but what is this about a corporate Gitea takeover?
AFAIK Gitea incorporated as a for-profit (which was supported), but there was some perceived shady-ness from the perspective of the community. You can read more here in the open letter: https://gitea-open-letter.coding.social/
