Code review tools are used to aid and automate existing peer code review practices in order to simplify and guide the review work flow. In general, code review is a systematic analysis of source code by a peer to find bugs which may have been missed by the original coder. <ref> GoogleTalksArchive "Mondrian Code Review on the Web" </ref>. The code review tools discussed here are collaborative tools designed for multiple users to easily share, review, and comment on one another's code to speed up the debugging process. Key features of code review tools include email notifications, syntax highlighted color diffs, commenting, reports, and subversion integration.

Barkeep
Barkeep is a code review system developed in Ruby by the company Ooyala <ref> GitHub "Comparing barkeep to other code review tools" </ref>. Although written in Ruby Barkeep is not language specific and may be used for code review of any language. Barkeep is standalone and the end user is responsible for hosting it. One of the key features that Barkeep prides itself on is it hackable nature. Since Barkeep is hosted by the user and they provide their “small codebase” it allows users to add on new features and make modifications as they see fit for their needs. So even if Barkeep doesn’t have a feature someone needs it is very feasible for the user to add it.
