I am looking for recommendations for an open source self-hosted version control system source code hosting service. I found a few, but I can’t decide on which one to pick:
If there’s a better one than the ones I’ve listed here, I’d love to hear about it!
I care primarily about privacy and security, if that makes any difference.
You’re missing GitLab. I’d be looking at GitLab or Forgejo.
But you might not need this. When you access a private Git repository, you’re normally connecting over SSH and authenticating using SSH keys. By default, if you have Git installed on a server you can SSH to and you have a Git repository on that server in a location you can access, you can use that server as a Git remote. You only really want one these services if you want the CI pipelines or collaboration tools.
Having a web UI is useful even if you’re not using the extra tools. Not mandatory of course, but nice.
