I've used it for a few years and it's been stable and without issue. builds.sr.ht is the best CI that I've ever used. I think the only time it has been down has been due to DDOS.

Would I run the git server of a multi-national bank on it? Probably not. A standard SAAS? Yeah if my team felt it was important to use EU companies.

Otherwise you could also self-host with a VM, then you can use gitea or gitolite with systemd oneshot services.
