It's not that bad actually, self-hosting is a thing – if you own the server, just set up your own Gitea or GitLab CE or something.

Shameless plug: I'm working on a tool which lets you get Gitea (or anything else that can be run with a docker-compose) running on a server in a couple minutes. You can install it with a single curl | sh, then you get a nice panel in which you can paste your Compose file, make a couple tweaks and click Deploy.

Gitea is actually the example app I picked for tutorial: https://lunni.dev/deploy/
