Now, I’ve never really felt like ReviewBoard was competing with Smart Bear Software’s Code Collaborator. I’m sure they see it that way, but it doesn’t have any bearing on the way we’ve run the project. We’re not concerned about feature checklists or keeping parity; we’ve been trying to make Review Board be the best tool we can for us, and all of our contributors have been doing the same. Comparisons to other tools rarely factor into the equation, since we don’t have a lot invested in whether people choose us or another. The way I view it, any sort of code review tool is a step in the right direction.
That said, this competitive analysis published on their web site had me giggling. The sheer amount of FUD and outright lies is staggering. My favorite bit is how Review Board doesn’t support pre-commit reviews for Perforce (which was the first thing it supported).
