Open Source Code Review Tools for GitHub and Self-Hosted Teams
Open source code review tools fall into two groups, and search results often mix them. Open source code review tools for GitHub run inside pull requests you already have: a GitHub Action or a CLI posts on the pull request, and the repository stays on GitHub. Self-hosted Git forges and review servers are the other group: they are where the repository, or the review request, lives. MergeJudge…
Open source code review tools for GitHub and self-hosted teams can be categorized into two groups. For GitHub, tools such as MergeJudge, reviewdog, Danger, and super-linter integrate directly into pull requests without replacing GitHub or acting as a Git server. These tools utilize various licenses, including MIT, GPL-3.0-or-later, and Apache-2.0, and support different review models like branch pull requests or patch-set changes.
They offer features such as linting, static analysis, policy checks, and auto, review, or block lane categorization. Self-hosted Git forges and review servers like Gitea, Forgejo, GitLab Community Edition, Gerrit, and more provide an alternative place for hosting code or running a review server adjacent to an existing Git host. These platforms also support branch pull requests and patch-set changes, and may require minimum approval counts for branch protection.
