Review Board is an open source web-based code review tool that helps development teams review code, documents, and images before committing changes.

It supports comprehensive repository integration including Git, Mercurial, Perforce, Subversion, ClearCase, and cloud services such as GitHub, GitLab, and Bitbucket. Power Pack extends capabilities with enterprise document review, reporting, and advanced repository support.

The code review market has consolidated around integrated Git platforms — GitHub, with roughly 38% of the source-code-management market, and GitLab, with about 16% — that bundle review into native pull and merge requests, shrinking demand for standalone dedicated review tools.

Within that consolidated landscape, Review Board remains relevant for teams needing unified review across heterogeneous and legacy version-control systems such as Perforce, Subversion, Mercurial, and IBM ClearCase, and for non-code artifact review including documents and images. Its outlook is therefore as a specialized tool for multi-SCM and document-review niches rather than the Git-centric mainstream.

Review Board differentiates itself through deep repository support, extensible Python APIs, WebHooks, and integrations with Slack, Discord, Jenkins, CircleCI, and other CI/CD tools.

The self-hosted deployment model keeps code and data private and secure within an organization's infrastructure. Power Pack adds enterprise document review, reporting capabilities, and advanced user role management for larger teams.

Review Board's diff-based, pre-commit review architecture creates friction for modern branch-based Git workflows, where most teams now expect GitHub- or GitLab-style pull or merge requests bundled directly into their hosting platform. Its interface is also described as dated compared with contemporary alternatives, and its setup complexity exceeds that of single-binary Git forges.

Independent comparisons note that Review Board is best suited to heterogeneous multi-VCS environments spanning Git, Subversion, Perforce, Mercurial, and ClearCase, and that Git-only teams tend to find its snapshot-based, pre-commit model misaligned with their practices. This has contributed to declining adoption as Git-centric teams migrate to integrated platforms.

Beanbag follows an open-core model built on Review Board, whose core code review platform is free and open source under the MIT license for self-hosted deployment. The company earns revenue from its hosted service and commercial add-ons rather than from the open source product itself.

RBCommons delivers Review Board as a managed cloud service with paid tiered plans, including a Business plan, that handle server maintenance and upgrades for customers. Power Pack, the commercial extension for document review and reporting, is bundled into paid on-premise plans and the Business hosted plan, alongside paid support contracts and sponsored feature development.
