What is CodeRabbit?
CodeRabbit is the most popular AI code review tool, providing line-by-line review on every pull request. It generates context-aware summaries, catches bugs, suggests improvements, and learns from team patterns. The platform integrates with GitHub, GitLab, and Azure DevOps.
CodeRabbit is free forever for public open-source repositories, with a 14-day free trial of the Pro plan for private repos. The tool runs automated reviews that include sandboxed environments, linting, security analysis, and integration with issue-tracking systems like Jira and Linear.
Founded in 2023 and headquartered in the United States, CodeRabbit has raised approximately $88M in total funding, including a $16M Series A led by CRV in August 2024. The company is rated 4.8/5 on G2 with 88% five-star reviews and is widely adopted by open-source projects and engineering teams.
