And can integrate with git? Examples?

I haven’t found a platform that handles issues integrated with git (as a technology) except, maybe, git-bug.

The wiki concept is simple; an external repo that’s a static site generator. All GitHub’s wiki happens to be is a fancy UI around Gollum wiki.

The protected branches and other git hooks are definitely part of the git-hooks feature that ship with the software.

Honestly, the full integration and friendliness to self-hosting had me seriously looking at Fossil, until I saw some opinions I couldn’t get on board with (e.g., automatically pushing to/pulling from remote on every commit)
