Crucible enables you to review code, discuss changes, share knowledge, and identify defects across SVN, Git, Mercurial, CVS, and Perforce. It creates formal, workflow-based, or quick code reviews and assign reviewers from across your team, turns any code review into a threaded discussion and comment on specific source lines, files, or an entire changeset, takes action on what's important with unified views into your code activity for commits, reviews, and comments, improves code quality with data on which parts of your codebase have not been sufficiently reviewed. Get a quick view of review status and who might be holding up reviews and access a complete audit trail with all code review details, down to the history of a specific review.
