56!

Those 3 are all fairly similar. Here are some others I can think of:

• Gitlab: many features, complex, pr workflow.
• Forgejo / Gogs: simpler, github inspired interface, pr workflow.
• Radicle: peer to peer, idk much more…
• Sourcehut: minimal (non-github) interface, very modular, email workflow.
• Cgit / Gitweb / etc.: just a git interface, no specific workflow.

If you’re not using any of the additional features, cgit should be enough. If you’re planning on collaborating with others, probably Forgejo would be better.

You can also use individual components of sourcehut, if you want a git web interface with just issue tracking, ci, or wiki, for example.

I feel like snac is social media made specifically for people who like C though. I’m sure most users of it are well aware of the implications.
