Review Board's primary competitive advantage is its open-source nature under the MIT License, allowing organizations to self-host and fully customize the platform. Unlike proprietary alternatives, Review Board supports an exceptionally wide range of version control systems.

The tool also offers unique capabilities such as deep image and document review, a powerful Python extension framework, and a mature API ecosystem. Its long development history since 2007 ensures stability and a proven track record in enterprise environments.

Review Board was originally created in 2006 by Christian Hammond and David Trowbridge while they were at VMware. The project was open-sourced in 2007 under the MIT License and has since grown into a mature code review platform.

In 2008, the founders established Beanbag, Inc. to provide commercial support and hosting services for Review Board. The company is headquartered in Palo Alto, California, and serves customers including Cisco, LinkedIn, and Yelp.

Review Board continues active development with regular releases, including RBTools command-line utilities and the Power Pack commercial extension. The product maintains strong community engagement through its documentation, support forums, and open-source contributions.

Organizations evaluating code review tools should consider Review Board for teams requiring self-hosted solutions, multi-VCS support, or integration with existing enterprise infrastructure. The commercial Power Pack adds enhanced features for reporting and authentication.
