If you work with GitHub then this codeberg.org has similar features.
On the official webpage I got these informations:
Codeberg is a community-driven, non-profit software development platform operated by Codeberg e.V. and centered around Codeberg.org, a Gitea-based software forge.
…
Codeberg is a non-profit volunteer effort. It relies on its friendly and dedicated community. We’re happy that you’re now a part of our community, too, and we hope you’re feeling welcome!
…
Projects on Codeberg use Git as their version control system.
It is hosted in Germany and is a open-source.
