Like the author, we self-host our git repos at work with Gitea, and it's working very well and brings a rather large set of features you'd expect from a GH alternative.

A great thing is that it's almost fully compatible with Github actions, so migrating an existing CI/CD should not be too painful. If you plan to move, make sure to read this first: https://docs.gitea.com/usage/actions/comparison#missing-feat...

For sure, it requires a bit of maintenance, mainly for updates, but that's all.
