Direct answer
What is CodeRabbit?
CodeRabbit automates pull request reviews, queue triage, and vulnerability detection by providing line-by-line committable feedback and architectural context.
CodeRabbit is an agentic code review platform designed to handle the influx of pull requests generated by development teams and AI coding agents. Integrated directly into version control platforms like GitHub and GitLab, it automatically examines pull requests, highlights potential issues, and offers committable line-level suggestions. Beyond basic syntax checks, the platform builds a code graph to track dependencies across files and services. It identifies logic errors, access control failures, server-side request forgery (SSRF), and LLM prompt injection vectors before code merges. The system learns project conventions from author responses and past reviews to refine future comments. To streamline code review workflows, CodeRabbit includes a Triage dashboard that ranks incoming PRs by complexity, effort, and risk level. It also offers Change Stack to break down multi-file diffs into logical layers with architectural diagrams. Optional add-ons provide automated codebase-wide security scans, interactive Slack triage agents, and autonomous cloud coding agents.
Unlike rule-based linters or generic PR summarizers, CodeRabbit traces data flow and multi-file dependencies across trust boundaries, continuously learns team-specific conventions, and directly loops with AI coding agents to verify fixes.
Product capabilities
Key features
Automated Pull Request Reviews
Scans diffs automatically and posts line-level comments with committable code suggestions and one-click fixes directly on PRs.
Continuous Convention Learning
Adapts to repository-specific rules and architectures based on developer replies and merged conventions over time.
PR Triage and Prioritization
Categorizes and prioritizes pull requests using risk, reward, effort, and blast radius metrics to route reviews efficiently.
Change Stack Diff Explainability
Deconstructs large code diffs into understandable dependency layers, semantic diffs, and architectural diagrams.
Multi-Agent Security Scanning
Checks code for IDOR, prompt injection, logic bugs, race conditions, and dependency vulnerabilities with reachability verification.
Coding Agent Review Loops
Interacts directly with automated coding agents to review their patches, request revisions, and verify adjustments before merge.
Pre-Merge and Post-Merge Actions
Enforces repository templates, docstring coverage, and title formats before merge, while triggering documentation updates or changelog PRs afterward.
Practical fit
Who should use CodeRabbit?
Automated PR Gatekeeping
Review every pull request before human reviewers inspect it, catching regressions, styling lapses, and missing test assertions.
Securing Agent-Generated Code
Analyze large agent-generated code submissions for security vulnerabilities like SSRF, race conditions, and business logic flaws.
High-Volume PR Triage
Organize open pull requests across multiple repositories by risk level and assign appropriate reviewers using an integrated triage board.
Incident Investigation and Slack Automation
Use the Slack agent add-on to correlate error monitoring alerts with recent PRs, trace regressions, and propose rollback or fix PRs.
Editorial assessment
Pros and limitations
Where it is strong
- Provides actionable, committable code fixes directly in pull request comments
- Free for all public open-source repositories without time limits
- Supports GitHub, GitLab, Azure DevOps, and Bitbucket
- Deep reachability checks minimize false positives on security alerts
- Learns repository conventions directly from developer comment feedback
Where to be careful
- Security PR reviews and continuous monitoring require the Advanced or Enterprise tier
- Enforces per-developer hourly PR review limits across plans under fair usage rules
- Usage-based billing applies to full codebase scans and agent add-ons beyond base seat costs

Frequently asked
CodeRabbit FAQ
Is CodeRabbit free for open-source projects?+
Yes. CodeRabbit offers free reviews forever on public repositories when installed via GitHub or GitLab, with no additional configuration required.
Does CodeRabbit use proprietary code to train AI models?+
No. According to CodeRabbit's privacy policy, neither CodeRabbit nor upstream model providers (OpenAI, Anthropic) use proprietary code submitted for review to train or refine models. Training is only conducted on open-source code.
Are review quotas unlimited?+
There is no total monthly cap on PRs or repositories, but plans feature per-developer hourly limits (ranging from 5 to 12 reviews per developer per hour depending on tier) subject to a Fair Usage Policy. Burst reviews can be enabled on a pay-as-you-go basis.
Which git hosting platforms are supported?+
CodeRabbit integrates with GitHub, GitLab, Azure DevOps, and Bitbucket.
How are seats billed on paid plans?+
Organizations are only billed for developers who create pull requests. Seats can also be manually assigned or reassigned at any time.
