My primary source code hosting platform is Codeberg.
Codeberg is a community-driven platform based in Germany and operated by a non-profit organization. It is based on Gitea, a lightweight Git service.
I have chosen Codeberg for its freedom of tracking and advertisements, as well as for the simplicity and speed of the user interface. I am currently migrating my projects from GitHub to Codeberg. I am keeping the repositories on GitHub as mirrors, though.
