FreemiumCodeRabbit 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.
FreemiumGreptile uses a credit-based pricing model. The Starter plan is free for 1 active developer with unlimited repositories and 50 credits/month (50 standard reviews or ~16 TREX reviews). No credit card required. The Pro plan is $30/seat/month and includes 50 credits per seat, with additional credits available at $1 each. Credits are consumed as follows: 1 credit = 1 standard PR review, 3 credits = 1 TREX runtime review (sandbox test execution).

Enterprise pricing is custom and adds SSO, audit logs, self-hosted deployment in your own AWS environment, BYOK (bring your own LLM providers), priority support, and dedicated SLAs. Greptile also offers free usage for qualified open-source projects and significant discounts for pre-Series A startups. A Greptile API is available at discounted bulk pricing for teams building on top of Greptile's codebase intelligence.

CodeRabbit Pros & Cons

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
Greptile

Greptile Pros & Cons

Pros

  • Deepest codebase context of any code review tool — builds a full graph of files, functions, and dependencies, not just the diff
  • 'Fix with Agent' button uniquely integrates with Claude Code, Codex, Cursor, Conductor, and Devin for automated review-fix loops
  • TREX runtime validation (Beta) writes and executes real tests in a sandbox — the only code review tool that actually runs the code
  • Free Starter plan for 1 developer with 50 reviews/month and unlimited repos — genuinely usable with no credit card required
  • Self-hosted and BYOK options for full data sovereignty in air-gapped and regulated environments
  • Trusted by Brex (CTO: 'outperforms them all by a mile'), NVIDIA, Retool, Substack, Scale, PostHog, Mintlify, Zapier, and 22,000+ teams

Cons

  • Credit-based pricing can be unpredictable — TREX runtime reviews cost 3 credits vs 1 for standard reviews, so heavy users of the most valuable feature pay 3x more
  • Pro at $30/seat/month is more expensive than CodeRabbit Pro ($24/user/month) for standard PR review without TREX
  • Founded 2023 by recent graduates — smaller team than competitors like CodeRabbit ($143M raised) despite raising a $30M Series A at $180M valuation
  • Series A reported in talks as of July 2025 but not confirmed closed — some uncertainty around funding timeline
  • Early culture of very long working hours was publicly noted by founder (9am–11pm, 6–7 days/week) — may affect team sustainability
