CodeRabbit

CodeRabbit is an AI-powered code review tool that automatically analyzes pull requests and posts detailed, human-readable feedback intended to catch bugs and speed up review cycles. When a pull request is opened, it generates an AI summary and walkthrough of the changes, checks the code against more than 40 integrated linters and security scanners, and can suggest one-click fixes through a "Fix with AI" feature. It also supports custom pre-merge checks, automatic unit test generation, and docstring generation, and includes a learning system that adjusts its feedback based on how reviewers respond over time. CodeRabbit connects to GitHub, GitLab, Azure DevOps, and Bitbucket for pull-request-based reviews, integrates with Jira and Linear for planning-linked workflows, and offers IDE extensions for VS Code, Cursor, and Windsurf alongside a CLI tool that runs reviews directly in the terminal — including for AI coding agents like Claude Code, Cursor CLI, and Gemini. The company states reviews are protected with end-to-end encryption and zero data retention post-review, backed by annual SOC 2 Type II audits. CodeRabbit is built for development teams and enterprises that want automated first-pass code review before a human reviewer gets involved. Pricing follows a freemium model with free IDE use and paid team plans; one limitation is that AI review still requires a human to confirm and merge any suggested fix.
