Crucible

Crucible finds bugs and improves code quality through peer feedback. It is a simple, light-weight process for doing pre or post commit code reviews from any web browser. It integrates with Subversion, Git, Mercurial, CVS and Perforce. Crucible supports several ways to share feedback with Workflow based reviews, quick reviews with cut and paste Snippets, and one-click reviews from change sets or issues. Automatically or manually notify reviewers who have not completed your code reviews. Set up reminders for reviews with due dates or manually "nudge" them to get their attention. Crucible provides multiple features to help your team stay on top of their workload. Crucible stores all code review details, down to the history of a specific code review
