Review Board

Review Board is a web-based review tool for source code, documents and images, developed by Beanbag. It supports Git, Mercurial, Perforce, Subversion, ClearCase, CVS, Azure DevOps, Jujutsu and other version control systems, and can be used for pre-commit and post-commit reviews.

Its diff viewer shows changes with syntax highlighting and moved-line detection, and reviewers leave comments and open issues that must be resolved. Configurable review and approval workflows keep an audit trail of decisions. RBTools provides a command-line interface and Python API to post changes, and Review Bot runs automated checkers and linters on review requests. Review Board can be extended with Python extensions, webhooks and CI integrations.

Review Board is open source under the MIT licence and can be installed on-premises or with Docker. The Power Pack add-on (document review, reports, extra integrations) is commercial, and RBCommons is a paid hosted version.
