I looked into this recently. But came up with.. nothing that worked me.
I think I was looking for something like Migadu[1] for git hosting. Cheap, private and for personal use. The best option is probably to self host.
I tried to fish out some ideas with an ASK HN thread but it did not get any attention: https://news.ycombinator.com/item?id=46011054
I have started putting my new stuff in Codeberg. Some of the private projects have manually update private mirrors on GCP (free so far).
