Greptile
AI code review agent that catches 3X more bugs by understanding your entire codebase.
Greptile is the most context-aware AI code reviewer we've tested, catching real bugs across multiple files and languages. TREX's ability to run tests and return evidence sets it apart from any competitor we've seen. At $30/seat/month it's pricey, but for teams shipping frequently, it pays for itself. If you're a mature engineering team that values code quality and uses AI coding agents, Greptile is a strong choice. Lighter alternatives like CodeRabbit are cheaper but lack the depth, while GitHub Copilot code review is a simpler starting point. For maximal safety, combine Greptile with a human review process.

Skip Greptile if you're a solo dev or tiny project with no formal code reviews, or if you're extremely price-sensitive and can't tolerate credit-based overage costs—free linters will do.
Going past 50 credits per seat per month costs $1 per extra standard review and $3 per TREX review, which adds up fast on teams that ship a lot of PRs.
Greptile's $30/seat/month Pro tier fits teams that ship a lot of PRs and value deep review. It's more expensive than CodeRabbit's ~$12/seat/month but offers execution (TREX) and agentic fixes. For serious engineering teams, the cost is justified by catching multi-file bugs; for small teams on a budget, it may be overkill.

About Greptile
Greptile is an AI code review agent that automatically reviews every pull request with full context of your codebase. It builds a graph index of your repository—files, functions, and dependencies—then uses a swarm of parallel agents to analyze changes beyond the diff, catching style violations, security risks, and multi-file logic bugs that human reviewers often miss. The tool learns your team's coding standards from PR comments, reactions, and replies, and supports custom rules written in plain English so you can enforce patterns your team actually cares about. A standout feature is TREX (now in public beta), which writes and runs tests for every PR in a sandbox environment, providing evidence like logs, screenshots, and videos to catch runtime bugs that static analysis cannot. This execution layer adds 20% more bug detection on top of traditional static review. Greptile also integrates deeply with AI coding agents—Claude Code, Cursor, Codex, Devin—offering one-click fixes and a /greploop for iterative resolution. For teams managing multiple repositories, Repo Clusters provides read-only access to shared repos during reviews, and the CLI delivers terminal-based reviews with machine-readable output. Usage is credit-based: standard reviews cost 1 credit, TREX reviews cost 3 credits, with $1 per additional credit. Over 9,000 teams including Brex, WorkOS, Browserbase, and Mintlify rely on Greptile. Pricing starts free for individual developers, $30/seat/month for teams, and custom enterprise plans with self-hosted deployment and SOC 2 compliance. Compared to lightweight linters like CodeRabbit, Greptile provides context-aware analysis across multiple files and adapts over time, making it better suited for mature engineering teams prioritizing code quality. Its v4 engine drives 74% more addressed comments per PR.
Behind the Verdict
Greptile stands out because it doesn't just look at the diff—it understands the whole codebase. The graph-based indexing means it can spot a function rename that breaks a caller in an unrelated file, a type of bug that static linters and human reviewers often miss. This is a genuine moat: building a codebase graph and training a review agent on your team's comments is substantial engineering, not just a thin prompt wrapper. TREX is the most exciting development. It actually runs your code in a sandbox, writes tests, and shows you logs, screenshots, and videos when something fails. This is a step beyond what any competitor we've seen does, and it's the kind of feature that could make Greptile indispensable for teams that ship risky changes. The public beta is a good time to trial it. Where Greptile really shines is in teams that already use AI coding agents like Claude Code or Cursor. The one-click fix and /greploop integration create a tight feedback loop: Greptile finds an issue, the agent fixes it, and Greptile re-reviews. This 'central validation layer' vision is well-executed. The learning system is another differentiator. It reads your team's comments, reactions, and commits, and after 2-3 weeks it stops flagging things you don't care about. This directly addresses the biggest complaint about AI review tools: noise. It's not perfect—you'll still get false positives on large PRs until you tune custom rules—but it's better than anything else we've tested. Weaknesses? The credit-based pricing can be unpredictable at high volume. With 50 credits per seat per month, a team of 10 doing 100 PRs a month with TREX would burn through credits fast and pay $1 per extra review. Flex usage limits (April 2026) let you cap spending, but you should set them early. Language coverage is thinner for niche languages like Scala or Kotlin. And if you're a solo dev or a tiny project that doesn't do formal reviews, Greptile is overkill—you'd be better off with a free linter. Overall, Greptile is a serious tool for serious teams. It's not the cheapest, but it catches bugs that matter, and it keeps getting better with TREX and the v4 engine. If you care about code quality and ship often, it's worth the money.

Models Under the Hood
as of 2026-07-31
Limitations
- False-positive fatigue can occur on large PRs until custom rules are tuned.
- Language coverage is strong for mainstream languages (Python, JS/TS, Go, Java, C/C++, C#, Swift, PHP, Rust, Elixir) but thinner for niche ones.
- Monorepos with 50k+ files take longer to index and re-index.
- Air-gapped/on-prem deployment is enterprise-only, so regulated industries should talk to sales early.
- Per-review overage pricing ($1/review beyond 50/seat/month) can make costs unpredictable at high PR volume, though flex usage limits (introduced April 2026) allow you to set a dollar cap.

Switching to or from Greptile
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From CodeRabbit: CodeRabbit is a lighter linter; moving to Greptile means configuring custom rules and letting Greptile learn your team's preferences from the start. No direct migration tool, but setup is quick and you
- ↗To GitHub Copilot code review: If you're already on GitHub and want a simpler, cheaper option, you can disable Greptile and use Copilot's built-in review, though you'll lose multi-file context and TREX.
