Chora provides a traditional tree-based view of the repository, with histories available in each individual file. We'll definitely have commit-based information (as we already support changesets in CVS and patchsets via cvsps), and we're looking at having more of a git-centric history view as well. But if you need to interface with your repository through PHP code, or if you're used to a primarily tree-based version control browser, or if you already use Chora or Horde, you might find this useful.
