gitea works well. Use that on your own network.

You could consider GitLab.. though this only seems to affect private forks of public repos.

I've been happy with Jetbrains Space (now Space Code); but I'm using it for private, professional work and paying for it, so perhaps that isn't what you mean.

JetBrains Space, Atlassian Bitbucket, GitLab (also On-Premises), Gitea

Order does not indicate any preference.

I've used both Bitbucket and Azure in the corporate world.
