If all you need is a repository, you don't even need any of these. You need SSH access to a server, and optionally, one of several web front-ends. Git comes with a CGI script that handles public anonymous checkouts via HTTP(S), although since nginx doesn't support CGI, integrating those is a little bit tricky as you need a FastCGI wrapper.

I moved most of my projects off GitHub to Forgejo and will be using Tangled too for public repositories. I don’t think people realize that if you self host Forgejo, you get 99% of the functionality of GitHub with zero of the limitations. Especially if you have the hardware to spare for CI runners. And if self hosting isn’t your thing you can always just use Codeberg and Tangled directly.

I’m working on an open source Forgejo browser called Joui. It’s coming along nicely, and is so much snappier than GitHub in every single way.
