Automated code review tool that integrates with any linter and posts results as comments on pull requests.
reviewdog is an automated code review tool that runs any linter or static analysis tool and posts the results as comments on pull requests or merge requests. It solves the problem of manually reviewing linter outputs by integrating directly with code hosting platforms like GitHub, GitLab, and Bitbucket, ensuring only new issues introduced in changes are highlighted.
Development teams and individual developers who use CI/CD pipelines and want to automate code quality checks in their review process, especially those working with multiple programming languages and linters.
Developers choose reviewdog because it is language-agnostic, supports virtually any linter, and seamlessly integrates with popular CI services and code hosting platforms, reducing manual review overhead and improving code consistency.

Supports any linter output using Vim's errorformat or pre-defined parsers for tools like ESLint and golint, as highlighted in the 'Input Format' section, making it language-agnostic.
Posts comments to GitHub PRs, GitLab MRs, Bitbucket Code Insights, and more via dedicated reporters, detailed in the 'Reporters' section, ensuring wide compatibility.
Offers multiple filter modes like added, diff_context, and nofilter to control which issues are reported, as explained in the 'Filter mode' section, allowing precise review focus.
Enables automated fixes via diff or RDFormat input, as shown in the 'Code Suggestions' section, helping teams implement changes directly from reviews.
For github-pr-check reporter, it relies on the reviewdog GitHub App server, which is a single point of failure and may not be available 24/7, as cautioned in the README.
Configuring errorformat for linters without pre-defined parsers requires understanding Vim's errorformat syntax, which can be challenging for non-standard tools.
Code suggestions are not supported by all reporters, such as github-check and bitbucket-code-report, as indicated in the 'Code Suggestions Support Table', reducing functionality in some setups.
Requires setting up and securing API tokens for GitHub, GitLab, etc., adding administrative overhead and potential security risks, especially in multi-environment deployments.
