I’ve been toying with a side project's POC and for one the moving pieces, I needed a Git server I could self-host.

One option I considered was using something like Gitea, but I eventually preferred something that was easier to customize and maintain by myself, so I needed a lighter solution. It turns out that Git itself already includes git-http-backend, a CGI program that allows to interact with a Git repository through the http[s] protocol.
