My main forge for projects on which I expect to collaborate is codeberg. I self-host a Forgejo instance for my personal projects. I have repositories on git.sr.ht, but I’m currently in the process of migrating to codeberg – don’t expect the old repositories to stay mirrored. Finally, I use github only if I’m contributing to a project hosted there.
Here are some of my projects you may be interested in. To see the rest, please check my profiles.
