It probably depends on your scale, but I'd suggest self-hosting a Forgejo instance, if it's within your domain expertise to run a service like that. It's not hard to operate, it will be blazing fast, it provides most of the same capabilities, and you'll be in complete control over the costs and reliability.

A people have replied to you mentioning Codeberg, but that service is intended for Open Source projects, not private commercial work.

We self-host Gitlab at work and it's amazing. CI/CD is great and it has never once gone down.

If you want to go really minimal you can do raw git+ssh and hooks (pre/post commit, etc).

I've been using https://radicle.xyz/ + https://radicle-ci.liw.fi/ (in combination with my own ci adapter for nix flakes) for about half a year now for (almost) all my public and private repos and so far I really like it.

Gitlab.com. CI is super nice and easily self hostable.

Codeberg is close to what i need

I left for codeberg.org and my own ci runner with woodpecker. Soooo much faster than github

At my last job I ran a GitLab instance on a tiny AWS server and ran workers on old desktop PCs in the corner of the office.

It's pretty nice if you don't mind it being some of the heaviest software you've ever seen.

I also tried gitea, but uninstalled it when I encountered nonsense restrictions with the rationale "that's how GitHub does it". It was okay, pretty lightweight, but locking out features purely because "that's what GitHub does" was just utterly unacceptable to me.

Gitlab.com is the obvious rec.

SourceHut.

Gitea is great.

gitea

Don't listen to the clueless suggesting Gitlab. It's forgejo (not gitea) or tangled, that's it.
