Guido van Rossum, of Python fame, has recently released a Django-based application that enables web-based code reviews… Rietveld.

It supports any language and currently can hook into Subversion repositories. You can see it running on Google AppEngine. Check it out!

Personally, I’m a big fan of Atlassian Crucible and have quickly come to realize the benefits of doing both on-line (in person) and off-line (web-based) code reviews.
