I think Radicle is interesting. It doesn't solve the CI bit, at least not yet, but I suppose it's possible to hook up some local runner for it.
There's also a bug tracker which I believe was called bug, but I can't find it ;), that tries to bridge different issue trackers and providing offline mode for working with them.
People of course also love free CI capacity where they can run even untrusted code, so in that sense Microsoft resources might be difficult to compete against.

Which is why we should always champion FOSS for dev tooling as it's the only way a community can have a say in an industry dominated by unregulated tech behemoths.
Will they? Has Gitlab doubled down on "Agentic AI" and thus require 30x capacity to support current users, while being kneecapped by Azure?
Same problem, capitalism, but different constraints.
