Anyway, hosting your own Gitea is easy and simple. And for FOSS game related stuff you are welcome to move your code to our https://git.freegamedev.net instance. It's hobby run though so there might be some rough times and I currently don't have a good backup system in place... I guess I should mention that on the page :/
