Is there a non-corporate alternative to GitHub?

  • Any Linux server with sshd installed is a git server if you want. There is even a bundled gitweb front end (some perl dependencies) if you need it. No other software needed

    I've ran that set up for many years with no need for GitHub/gitlab features

  • Gitlab, Sourcehut, Gitea, or Gogs? Or cgit?

  • You might like https://codeberg.org/.

  • Sourcehut. https://sr.ht

  • https://libreplanet.org/wiki/FSF_forge_evaluation

    Lots of FOSS projects run their own places, e.g. debian salsa, and of course you can run git anywhere. I guess you are mostly refering to the showcase/discovery aspect of github. For that many people just use github or gitlab for the visibility.

    I am not aware of a "brandname" FOSS-only place, but apparently the fsf wants to change that.

  • You haven't checked out GitLab?

  • Stand up your own git server.

  • What do you mean by non corporate?

    501c3s (nonprofits) are a form of corporation.
