CodeRabbit is an AI-powered code review platform that automatically analyzes pull requests and local changes, built and operated by CodeRabbit, Inc. Rather than replacing human reviewers, it generates PR summaries, architectural walkthroughs, and inline comments that flag bugs, security issues, and edge cases before a human ever opens the diff.
Who builds it
- CodeRabbit, Inc. was founded in early 2023.
- The company raised a $60 million Series B in September 2025, led by Scale Venture Partners with participation from NVIDIA's venture arm NVentures, at a $550 million valuation, bringing total funding to $88 million.
- CodeRabbit reports 6 million repositories reviewed, 75 million defects found, and more than 15,000 customers, including NVIDIA.
Core features
- Automated pull-request reviews with plain-language summaries, sequence/architecture diagrams, and line-by-line comments.
- "Fix with AI" one-click commits for suggested changes, plus custom pre-merge checks, unit test generation, and docstring generation on higher tiers.
- "Learnings": the system accepts developer feedback on its comments and adapts future reviews accordingly.
- Configurable via YAML for team-specific coding guidelines and workflow rules.
- Works across Git platforms — GitHub, GitLab, Azure DevOps, and Bitbucket — and is also available as an IDE extension (VS Code, Cursor, Windsurf) and a CLI for reviewing code before it's even pushed.
- CodeRabbit says it is designed to work with all programming languages, citing Python, JavaScript, Java, C++, and Ruby as examples.
Pricing
- Free ($0/month): unlimited public and private repositories, PR summarization, and IDE/CLI reviews, plus a 14-day trial of Pro Plus features with no credit card required.
- Open Source ($0, permanent): free reviews forever when installed on public repositories on GitHub or GitLab.
- Pro ($24/month per user, billed annually): linters/SAST support, Jira and Linear integrations, agentic chat, analytics dashboards, docstring generation, up to 5 MCP connections, and pre-merge checks.
- Pro Plus ($48/month per user, billed annually): everything in Pro plus custom pre-merge checks, unit test generation, automatic merge-conflict resolution, an issue planner, and higher usage limits.
- Enterprise (custom pricing): everything in Pro Plus plus RBAC, SSO, audit logging, API access, self-hosting, multi-org support, SLA support, and EU SaaS deployment.
- An optional Slack agent for incident investigation and task automation is billed separately at $0.50 per agent-minute.
Privacy and security
CodeRabbit says it holds SOC 2 Type II certification, validated through annual independent audits, and states that source code is not retained after a review completes (except where a customer opts into review caching to speed up future runs) and is not used to train models.
Who it's for
CodeRabbit is aimed at teams that want AI to triage and pre-screen every pull request — from solo maintainers of open-source repos, who get reviews for free, to enterprises that need SSO, audit logging, and self-hosted deployment for regulated environments.
