Our verdict on reviewdog

reviewdog is an open-source command-line tool for automated code review. It accepts compiler, linter, diagnostic, SARIF, and diff output, filters findings against code changes, and reports them locally or to code-hosting services. It is suited to CI teams that already generate diagnostics and want those findings presented in pull requests, merge requests, change reviews, checks, annotations, or commit reports. It can run locally or in CI environments across web, Windows, macOS, Linux, and self-hosted setups.

Its main strength is platform and format coverage. reviewdog supports GitHub, GitLab, Gerrit, Bitbucket, and Gitea, with workflow integrations including GitHub Actions, GitLab CI, Bitbucket Pipelines, Jenkins, Travis CI, and CircleCI. It accepts errorformat, RDFormat, checkstyle, SARIF, and diff inputs, while .reviewdog.yml provides configurable runners. Reporting options include GitHub checks and pull-request reviews, GitLab merge-request discussions and commits, Gerrit change reviews, and Bitbucket Code Insights reports. Teams working across different code hosts can keep their existing diagnostic tools while changing how results reach reviewers.

The product is intentionally focused on routing and presenting diagnostics rather than performing a complete review on its own. Its published positioning centers on changed-line filtering, review comments, code suggestions, and CI delivery, so it fits teams with established linters, compilers, formatters, or other diagnostic tools. reviewdog is distributed as MIT-licensed open-source software, with no paid tier structure described. Choose it when self-hosting, workflow control, and code-host coverage matter; choose a different category tool when you need built-in security analysis, review analytics, or AI-based review capabilities.
