Review Board is an open source, web-based code and document review tool built to help companies, open source projects, and other organizations keep their quality high and their bug count low.

We began writing Review Board in 2006 to fill a hole in the code review market. We wanted something open source that could be flexible enough to work with a variety of workflows, and could take the pain out of the code review process.

Today, it's a vital part of the development process at thousands of projects and companies, ranging from small startups of two people to enterprises of thousands.

Review Board tracks changes to your pending code, graphics, documents, and all discussions around all the decisions made about your product. Our diff viewer does more than just display diffs: It shows you exactly how your code was changed, with syntax highlighting, interdiffs, moved line detection, indentation change indicators, and more.

You can integrate with Review Board using its rich API and extension frameworks, allowing custom features, review UIs, data analysis, and more to be built without ever having to fork Review Board.

There's support for Bazaar, ClearCase, CVS, Git, Mercurial, Perforce, Plastic, and Team Foundation Server, hosted on your own server or on Assembla, Beanstalk, Bitbucket, Codebase, GitHub, GitLab, Gitorious, Kiln, or Unfuddle.

If you're an end-user already using Review Board, you'll want to install RBTools, our command line suite for working with Review Board.

RBTools makes it easy to post changes for review, land reviewed changes, patch your local tree with someone else's changes, check your workload, and much more.

RBTools can be installed on Windows, Linux, Mac, and other platforms. See the RBTools documentation for everything it can do.

We can help you get going with Review Board, and diagnose any issues that may come up. There are two levels of support: Public community support, and private premium support.

The public community support is available on our main discussion list. We generally respond to requests within a couple of days. This support works well for general, non-urgent questions that don't need to expose confidential information.

We can also provide more dedicated, private support for your organization through a support contract. We offer same-day responses (generally within a few hours, if not sooner), confidential communications, installation/upgrade assistance, emergency database repair, phone/chat (by appointment), priority fixes for urgent bugs, and backports of urgent fixes to older releases (when possible).

There are thousands of companies and organizations using Review Board today. We respect the privacy of our users, but some of them have asked to feature them on the Happy Users page.

If you're using Review Board, and you're a happy user, let us know!.
