About CodeRabbit

CodeRabbit is the pioneer of AI code review and the most widely deployed AI code review platform, founded in 2023 by Harjot Gill (CEO) and Gur Singh (COO) in San Francisco. It automatically reviews every pull request using a codegraph, adaptive systems, and an ensemble of AI models, posting inline comments, 1-click fixes, walkthrough summaries, and security findings — all within native GitHub, GitLab, Azure DevOps, and Bitbucket interfaces. It integrates with Jira, Linear, Discord, and Slack, and uniquely loops with AI coding agents (Codex, Claude Code, Cursor, Gemini) so agents can address review feedback automatically.

In August 2026, CodeRabbit raised a $143M Series C at a $1.5B valuation co-led by Atomico and Smash Capital, bringing total funding to $231M. Revenue grew more than 5x year-over-year; the platform now conducts over 2 million code reviews per week for 17,000+ customers including NVIDIA, BMW, Adyen, Indeed, JFrog, Trivago, and Campfire, with over 150,000 open-source projects using it for free. Jensen Huang (CEO of NVIDIA) publicly stated: "We're using CodeRabbit all over NVIDIA."

Alongside the Series C, CodeRabbit introduced Agentic Change Management — four pillars to help teams govern AI-generated code: Review (agentic PR and CLI review), Triage (PR prioritization queue), Change Stack (explainability layer for massive diffs with semantic groupings and architectural diagrams), and Security (continuous vulnerability and secrets scanning with AI-verified findings). A free VS Code/Cursor/Windsurf extension and CLI extend reviews into the IDE and terminal. A Slack agent handles incident investigation, feature planning, and support case triage at $0.50/agent-minute.

Key Features

Agentic PR code review — context-aware inline comments, 1-click fix suggestions, walkthrough summaries, and learning from team feedback on every pull request
Triage — scores, ranks, and routes PRs by business value, risk, complexity, and effort to help teams prioritize a flood of AI-generated changes
Change Stack — breaks massive diffs into logical cohorts with semantic summaries, blast radius context, and architectural diagrams for explainability
CodeRabbit Security — continuous repository scanning for code vulnerabilities, leaked secrets, and vulnerable dependencies with AI-verified findings and auto-generated fix PRs
Loops with coding agents — CodeRabbit posts review feedback and your AI agent (Codex, Claude Code, Cursor, Gemini) loops back to address it automatically
IDE & CLI reviews — free VS Code extension for real-time commit reviews, and a CLI (coderabbit review) that adds review capability to any terminal-based coding agent
CodeRabbit Agent for Slack — codebase-aware agent that investigates incidents, triages support cases, plans features, and generates PRs directly in Slack ($0.50/agent-minute)
Integrations — GitHub, GitLab, Azure DevOps, Bitbucket, Jira, Linear, Discord, Slack; MCP connections (5 on Pro, 15 on Pro Plus, 20 on Enterprise)

Pros

Pioneer and market leader in AI code review — first to market, 17,000+ customers, 2M+ reviews/week, most installed AI app on GitHub and GitLab
NVIDIA's Jensen Huang uses it company-wide — the strongest possible enterprise validation signal
Free for all open-source projects — $10M committed over next 12 months to keep OSS features free
Uniquely loops with AI coding agents (Codex, Claude Code, Cursor, Gemini) for fully automated review-fix cycles
Agentic Change Management covers the full governance lifecycle: Review, Triage, Change Stack, and Security in one platform
Revenue grew 5x+ year-over-year with $143M Series C at $1.5B valuation in August 2026

Cons

No free permanent commercial tier — only a 14-day trial and free access for open-source projects
Pro plan at $24/user/month (annual) adds up quickly for larger teams compared to per-repo pricing models
Primary focus is code review/governance rather than inline autocomplete or code generation — not a Copilot replacement
Rate limits on Pro (5 PR reviews/hour) and Pro Plus (10/hour) may constrain teams with very high PR velocity
CLI and IDE reviews are newer additions — not as mature as the core PR review feature

Pricing

CodeRabbit offers a 14-day free trial with no credit card required, and a permanent free plan for open-source projects. The IDE extension (VS Code, Cursor, Windsurf) is free for all users.

The Pro plan costs $24/user/month (billed annually) or $30/user/month (monthly), and includes agentic PR and CLI reviews, 1-click fixes, learnings, agent loops, up to 5 MCP connections, pre-merge checks, agentic chat, linter/SAST integration, and Jira/Linear integrations. Pro Plus is $48/user/month (annual) and adds multi-repo analysis (up to 10 repos), custom pre-merge checks (up to 20), finishing touches (unit test generation, merge conflict resolution), post-merge actions, issue planner, and higher rate limits (10 PR reviews/hour). CodeRabbit Security is a separate add-on at $40/user/month for continuous repository scanning and per-PR security review. The CodeRabbit Slack Agent is usage-based at $0.50/agent-minute.

Enterprise pricing is custom and includes all Pro Plus features plus custom RBAC, SSO/SAML, audit logs, API access, self-hosting, multi-org support, SLA support, dedicated CSM, EU SaaS deployment, and AWS/GCP/Claude marketplace billing.

Frequently Asked Questions

CodeRabbit is the most widely deployed AI code review platform. It automatically reviews every pull request using contextual AI, posting inline comments, 1-click fix suggestions, walkthrough summaries, and security findings. It integrates natively with GitHub, GitLab, Azure DevOps, and Bitbucket, and connects with Jira and Linear for issue tracking. The bot loops with AI coding agents to address review feedback automatically.

CodeRabbit was founded in 2023 by Harjot Gill (CEO, formerly Senior Director at Nutanix after its acquisition of his startup Netsil) and Gur Singh (COO, formerly at Alegeus). In August 2026 it raised a $143M Series C at a $1.5B valuation, bringing total funding to $231M. Previous rounds were a $16M Series A (August 2024) and a $60M Series B (September 2025).

The Pro plan costs $24/user/month (billed annually, or $30/month billed monthly) and includes agentic PR and CLI reviews, 1-click fixes, learnings, agent loops, MCP connections, pre-merge checks, agentic chat, linters, and Jira/Linear integrations. Pro Plus is $48/user/month (annually) and adds multi-repo analysis, custom pre-merge checks, post-merge actions, unit test generation, and higher limits. Enterprise pricing is custom.

Yes. Open-source projects get CodeRabbit's AI code review completely free. CodeRabbit has committed to spending more than $10 million over the next 12 months to keep code review and agent capabilities free for open-source projects and maintainers. More than 150,000 open-source projects already use CodeRabbit.

Agentic Change Management is CodeRabbit's positioning for the era of AI-generated code. It encompasses four pillars: Review (agentic PR and CLI review), Triage (PR prioritization and routing queue), Change Stack (explainability for massive diffs with semantic layers and architectural diagrams), and Security (continuous repository scanning for vulnerabilities and secrets). Together these form the control layer organizations need to govern code from humans and AI agents alike.
