CodeRabbit
CodeRabbit is an AI code review assistant for GitHub and GitLab that summarizes pull requests, reviews changes line by line, and can run incremental reviews on commits, helping teams catch issues earlier while keeping feedback inside the PR workflow.
Overview
CodeRabbit is a pull request focused AI reviewer that integrates with popular Git hosting platforms including GitHub and GitLab. Its core workflow centers on understanding what changed in a PR, generating a structured summary, and providing review feedback directly on the diff. On its pricing page CodeRabbit lists a Free plan that includes PR summarization and reviews in the IDE, with a 14-day free usage of the Pro plan and support for unlimited public and private repositories.
For deeper review automation, CodeRabbit describes Pro as offering comprehensive pull request reviews and advanced insights, and public repository materials describe features such as line-by-line code change suggestions and continuous incremental reviews that run on each commit rather than only once per PR. This makes CodeRabbit useful for teams that want consistent review coverage across many repos, especially when reviewer time is limited. In practice, teams often treat CodeRabbit as a first pass reviewer that flags risks and drafts suggestions, while humans confirm correctness and align changes with product context.
When evaluating fit, check how it handles your languages and frameworks, whether its suggestions match your code standards, and how it fits into existing review policies for security and compliance.

Capabilities
Pull request summary
Generate PR summaries that describe what changed and why it matters. This helps reviewers understand scope faster and reduces time spent reconstructing intent from diffs and commit history.
Line by line review
Review the pull request diff and post concrete suggestions near the relevant lines. Designed to provide actionable feedback that developers can apply directly while still requiring human verification.
Incremental reviews
Run reviews on each new commit to keep feedback aligned with the latest state of the PR. This reduces stale comments and helps maintain signal as the author iterates.
Reviews in IDE
Access review information in IDE workflows so developers can fix findings while coding. This can shorten the loop between receiving PR feedback and applying updates in the code editor.
Frequently Asked Questions
How does CodeRabbit pricing start?
CodeRabbit lists a Free plan at $0 that includes PR summarization and reviews in IDE, plus a 14-day free usage of the Pro plan without a credit card. Pro is listed at $24 per month with more comprehensive reviews.
What should teams consider for privacy and risk?
CodeRabbit operates on pull request content, so teams should confirm what code is transmitted to AI models, how long data is retained, and whether the tool meets internal security review requirements for third-party services.
Which integrations are officially supported?
CodeRabbit highlights support for GitHub and GitLab, and it is designed to comment within pull request workflows. Validate how it connects to your repos, what permissions it requires, and whether it supports your branching policies.
What setup and support is needed?
Setup typically involves installing the app and granting repository access, then enabling review behavior for repos or orgs. Evaluate support expectations by plan, and define guidelines for when humans must override AI review output.
How does CodeRabbit compare to manual review?
CodeRabbit can speed up understanding and highlight issues, but it does not replace human responsibility for correctness and product context. Treat it as a consistent first pass that improves coverage while reviewers make final decisions.
