Gitea is an open source Git service and completely free of charge. The site uses, as the name suggests, Gitea which allows everyone to run their own Git service! We use this git service ourselves to publish the source code of our self-written pages! This can also be used further on if you credit it!
There are no ads and no trackers on the site and with an account you can host your code on the platform. Pretty much trade free! 5/5 blocks from me.
