CodeRabbit
FreemiumAI code reviews on every pull request.
Published 27 September 2026
Scores
Popularity4/5
The most-installed AI app on the GitHub Marketplace, with over two million connected repositories, more than 17,000 customers, and a $1.5B valuation. Well known among developers who work with pull requests, though AI code review is still a young category many developers have not adopted.
Learning Curve1/5
Setup is installing a Git app and picking repositories; the first review arrives on the next pull request with no configuration. The YAML config and path instructions are optional refinements.
Flexibility4/5
Path-specific instructions, learnings from PR replies, custom pre-merge checks, and four Git hosts plus IDE and CLI surfaces give teams a lot of control over what gets reviewed and how. The underlying models are chosen by CodeRabbit, not the user.
Performance3/5
Reviews arrive within minutes and PR summaries are widely praised, but independent bug-catch benchmarks put its detection rate well behind Greptile and some other reviewers, and noisy comments are a common complaint.
Portability3/5
Works across GitHub, GitLab, Bitbucket, and Azure DevOps and sits outside the codebase, so switching reviewers is an app uninstall. It is a hosted SaaS, and learnings and configuration do not carry over to other tools.
About CodeRabbit
CodeRabbit is an AI code review platform that installs as an app on a Git host and reviews every pull request as it is opened and updated. It reads the diff against the wider repository for context, runs more than 40 linters and security analyzers alongside its language models, and posts a summary, a walkthrough of the change, and line-level comments that can be applied as one-click fixes. Developers can reply to the bot in the PR thread to ask questions or correct it, and it stores those corrections as learnings for later reviews.
It works across GitHub, GitLab, Bitbucket, and Azure DevOps, and the same review engine is available before a PR exists through extensions for VS Code, Cursor, and Windsurf and through a command-line tool, so code written by a person or by a coding agent can be checked before it is pushed. Review behaviour is configured in a .coderabbit.yaml file with path-specific instructions, and the higher plans add custom pre-merge checks, unit-test generation, merge-conflict resolution, and a security review with blast-radius analysis.
CodeRabbit is free for public open-source repositories, where it offers its Team features, and has a free tier for private repositories with PR summaries and rate-limited reviews. Paid plans bill only developers who open pull requests; everyone else on the repository reviews for free. The company reports more than two million code reviews a week across over 17,000 customers, and it is the most-installed AI app on the GitHub Marketplace.

Tools Related to CodeRabbit
Integrates with CodeRabbit(3)
CodeRabbit installs as a GitHub App and posts its review directly on pull requests — a walkthrough summary plus line-level suggestions on each diff.
CodeRabbit reviews GitLab merge requests natively, posting the same walkthrough and line-level comments without GitHub being involved at all.
CodeRabbit's IDE extension runs inside Cursor (and VS Code and Windsurf), bringing the same review to the editor before a PR exists — the Git-host integration covers PRs without it.
Alternatives to CodeRabbit(2)
The two dedicated AI code review platforms: CodeRabbit covers more Git hosts (Azure DevOps and Bitbucket included) and has a free tier for open source, while Greptile leans on whole-repo context and offers a self-hosted deployment.
CodeRabbit reviews the full pull request — code quality, security, performance, and docs — and is editor-agnostic, while Cursor Bugbot focuses narrowly on catching bugs and is billed through a Cursor plan rather than its own subscription.
