I'm curious: What are the best free GUI for Git?

I'm surprised nobody mentioned Git Extensions yet. My absolute favorite Git UI, better than my previously favorite git-cola.

I'm a big fan of GitLab. Clean design, intuitive interface, many features.

Disclaimer: I'm now a GitLab authorized training partner and reseller. The community edition is free. :)

I'm a fan of tig on the command line and Gitbox (Mac GUI).

gitk - it's built into git, and supplements (not replaces) the command line. It does tree visualization and diffs between commits.
