CodeRabbit

What CodeRabbit is

CodeRabbit is an AI-powered code review tool that acts as an automated reviewer on every pull request. Once installed on a Git platform, it posts a summary and walkthrough of the changes, then leaves line-by-line review comments that flag bugs, logic errors, security issues, and style problems a human reviewer might miss. It generates sequence and architecture diagrams to give context, and offers one-click fixes for simple issues plus AI-assisted suggestions for complex ones. A distinctive trait is its codebase awareness: it uses code-graph analysis to understand dependencies across files rather than reviewing a diff in isolation, and it can pull in external context from Jira and Linear issues, MCP servers, and web queries.

It runs more than 40 open-source linters and SAST scanners as part of each review, so language coverage is broad and findings include static security analysis. Teams configure it with a YAML file for coding guidelines and workflows, and it learns from natural-language feedback over time, so its reviews adapt to a team's conventions. Beyond the PR, it generates docstrings, unit tests, and standup or sprint reports, and works in VS Code, Cursor, and Windsurf plus a CLI. It is positioned to complement human review by handling the repetitive first pass, not to replace reviewers.

Where CodeRabbit is the strongest pick

CodeRabbit is strongest for teams that run a high volume of pull requests and want a consistent automated first pass before human review. It shines when reviewers are a bottleneck, when onboarding junior developers who benefit from inline explanations, and when a team wants enforceable, codified review standards via YAML config. Its broad linter and SAST integration makes it a good fit where security and style consistency matter across many languages, and its per-PR-author billing keeps cost reasonable for teams where only some members open pull requests.

Pricing

Free access: CodeRabbit no longer lists a $0 plan in its pricing table. Sign up with GitHub or GitLab, install CodeRabbit on a public repository, and you receive free reviews forever for public repositories. All plans include a 14-day free trial, with no credit card required. CodeRabbit has also renamed its paid tiers: the $24 and $48 annual price points we previously published as Pro and Pro Plus are now sold as Essentials and Team.

• Essentials: $24/dev/mo (billed annually, $30/dev/mo monthly). 40+ linters and SAST, autofix, custom instructions, Jira and Linear, agentic chat, analytics.
• Team: $48/dev/mo (billed annually, $60/dev/mo monthly). everything in Essentials plus unit test generation, custom pre-merge checks, and higher limits.
• Advanced: $72/dev/mo. Sits between Team and Enterprise in the pricing table.
• Enterprise: Custom (contact sales). self-hosting, SSO and SAML, RBAC, audit logs, API access, EU deployment, and SLA support.

Confirm current pricing before purchase.

Best for

Small to mid-size engineering teams and open-source maintainers who want faster, more consistent code review without adding headcount. It is especially useful for teams already on GitHub or GitLab that need an automated reviewer to catch bugs and enforce standards before a human signs off.

FAQ

How much does CodeRabbit cost?

CodeRabbit's pricing table lists four tiers and none of them is $0. Essentials is $24 per developer per month billed annually, or $30 per developer per month billed monthly, and unlocks autofix, 40+ linters, custom instructions, and integrations. Team is $48 per developer per month billed annually, or $60 per developer per month billed monthly, and adds unit test generation, custom pre-merge checks, and higher limits. Advanced is $72 per developer per month and sits between Team and Enterprise. Enterprise is custom-priced and adds self-hosting, SSO, audit logs, and SLA support. All plans include a 14-day free trial with no credit card required, and public repositories get free reviews forever. Billing applies only to developers who open pull requests, so reviewers and managers are not charged.

Is there a free version of CodeRabbit?

Not as a $0 plan. CodeRabbit's pricing table now lists four paid tiers, Essentials, Team, Advanced, and Enterprise, with no $0 plan among them. Free access comes in two forms instead: sign up for CodeRabbit using GitHub or GitLab, install CodeRabbit on a public repository, and receive free reviews forever for public repositories; and all plans include a 14-day free trial, with no credit card required. That free-forever access is scoped to public repositories, so the permanent free plan covering unlimited public and private repositories that we previously published no longer holds.

Does CodeRabbit replace human code review?

No. CodeRabbit is designed to complement human review, not replace it. It automates the repetitive first pass by summarizing changes, flagging likely bugs, security issues, and style problems, and suggesting fixes, so human reviewers can focus on architecture, intent, and tradeoffs. The AI provides context-aware feedback and can answer questions in chat, but final approval and judgment stay with the team. In practice it shortens review cycles and catches issues a busy reviewer might overlook, while a person still signs off on the merge.

What programming languages does CodeRabbit support?

CodeRabbit supports all major programming languages, including JavaScript, TypeScript, Python, Java, Kotlin, Go, Ruby, Rust, C, C++, PHP, and Swift, among more than 20 others. It improves language-specific feedback by running dedicated linters such as Ruff for Python and golangci-lint for Go, and it integrates over 40 linters and static analysis tools overall. Review quality can vary by language depending on available training data, but coverage is broad enough that most teams will find their stack well supported.

Is CodeRabbit secure and private with my code?

CodeRabbit is SOC 2 Type II certified with annual independent audits and is GDPR compliant. It uses SSL-encrypted data transfer and operates a zero data retention policy, meaning your code is not stored after a review completes and is not used to train AI models. For organizations with stricter requirements, the Enterprise plan offers self-hosted deployment, an EU SaaS region, single sign-on, role-based access control, and audit logging, so code and review data can stay within a controlled environment.

Which platforms and tools does CodeRabbit integrate with?

CodeRabbit integrates with the major version control platforms: GitHub, GitLab, Bitbucket, and Azure DevOps. It connects to issue trackers Jira and Linear for context, posts to Slack, and supports MCP servers and web queries for external context. Beyond pull request review, it works directly in IDEs including VS Code, Cursor, and Windsurf, and offers a command-line interface for local reviews. Setup is typically a two-click install through your Git provider, and review behavior is customized with a YAML configuration file in the repository.
