Its incredibly trivial to just host up your own instance if gogs or gitea on a cheap computer, throw woodpecker on it if you want easy CI/CD

It doesnt take much hardware at all for a git server, a raspberry pi will handle it just fine.

Or just a cheap box liquidated from some office, just go buy some box from a used pc seller in your city, they'll have some.

Toss a 1TB drive in it.

Throw debian on it.

Install Gogs + Woodpecker

And then set em up and connect the two together.

Grats, you have your own self hosted git server whee
