Bitbucket lol .I would rather not.
I used to love gitlab (great CI!) but the quality is really going down. Everything is slow and there UI is full of bugs (god I hate there virtual srolll in epics).
There is also sourcehut. They have the best CI for me but sadly issue / merge request management is mail based.
Gitea looks like it is going the gitlab way with enterprise support and cloud because they need to make money.
Forgejo is cool (how do you prononce it?) but I am really sad they based there CI on github action.
The routing feature is so cursed XD
