If you're on the Fediverse and you want to host code for libre software and other collaborative projects, you might want to check out @gitea:
It's free, open source and it's currently in process of adding Fediverse compatibility through ActivityPub, the same standard that Mastodon etc use to communicate with each other.
You can see some of the Gitea instances that already have experimental Fediverse connections listed at https://fedidb.org/software/gitea
To see the current state of federated forges, have a look at the @forgefriends blog post at https://forgefriends.org/blog/2022/06/30/2022-06-state-forge-federation/
