It's a tangent, but I think it's interesting that Gitea started trying to self host in Feb 2017 (https://github.com/go-gitea/gitea/issues/1029) and hasn't got there yet (based on how active the github issues/PR page are).
https://about.gitea.com/ offers me a "free cloud trial" and otherwise sounds very like other web front ends to git. So like github, except they don't trust it themselves.
In contract forgejo has "Self-hosted alternative to GitHub" written in big letters on the landing page. https://codeberg.org/forgejo is indeed self hosted.
