I am trying to share a private GitHub repository of a Java app with people who has not a GitHub account. When I add collabrator via email, it sends link to that mail but requires GitHub account to read shared repo.
So, is it possible to share repo with a person who has not GitHub account?
If they do not need the full history, but only the latest code, sending an archive (git archive or GitHub tarball) is enough.
That is the equivalent of a git bundle limited to one commit.
If they need to look at the history, and the bundle is not an option, then they need a GitHub account, as anonymous browsing is not available for a private repository.
