AI code review agent that indexes your whole codebase, not just the diff, to catch cross-file bugs before merge; used by 22,000+ engineering teams.
Greptile suits engineering teams on GitHub or GitLab who want deeper pull request review than a diff-only bot gives. Founded in 2023 and backed by Y Combinator, it trades review speed for depth, tracing dependencies across an entire codebase instead of scanning only the changed diff like lighter competitors.
Multi-hop cross-file bug detection from a whole-repo semantic graph, catching dependency breaks a diff-only reviewer cannot see.
Full-repo semantic indexing and multi-hop agent reasoning are hard to replicate cheaply, but CodeRabbit and Qodo are closing the accuracy gap while offering less noisy diff-only review, so the moat is technical depth rather than lock-in.
Main trade-off
Highest false-positive rate among major competitors in independent benchmarks, and no free tier existed before its general availability in mid-2026.

Free Starter tier for a solo developer; Pro is usage-based at $1 per credit, billed per credit rather than per seat, with a 14-day trial; Enterprise terms are quoted by sales.

More than 22,000 teams, including Nvidia, Brex, and Zapier, use Greptile for AI code review, according to its maker. It builds a semantic graph of an entire repository before reviewing a pull request, tracing dependencies and git history across files to flag cross-module bugs. It announced a $50M Series B in October 2026.
Semantic Graph Index
Builds a graph index of every function, class, import, and commit in a repository before reviewing a pull request, so comments account for cross-file impact instead of just the diff.
v4 Multi-Hop Agent
The March 2026 v4 agent traces dependencies and git history across files in a reasoning loop, lifting addressed-comments-per-PR by 74% over the prior single-pass version.
Confidence-Scored Comments
Every review comment carries a confidence score so developers know which flags to act on first.
Custom Rules in Plain English or YAML
Teams define review directives through a .greptile.yaml file, a linked markdown style guide, or scoped plain-English rules for specific paths.
Learns From Team Feedback
A memory layer watches how engineers respond to past comments, reactions, and commits, and tunes what it flags next time.
Open MCP Server
An MCP server hands Claude Code, Cursor, VS Code, and Codex CLI direct access to PR data, review comments, and custom context so those agents can act on flagged issues in the editor.
Self-Hosted Enterprise Deployment
Enterprise customers can run Greptile inside their own AWS environment with their own LLM provider for air-gapped review.
Most users expect these and they are not currently supported.

Proprietary
Starter is free for one active developer, with unlimited repositories and 50 credits a month. Pro has no seat fees: credits cost $1 each for unlimited developers and agents, and it begins with a 14-day free trial. Enterprise is custom-priced and adds self-hosting, SSO/SAML, and role-based access control. Spend scales with credits used rather than headcount.
Yes. The Starter tier is free for one active developer and covers unlimited repositories with 50 credits every month. Teams with more than one developer move to the pay-as-you-go Pro plan. Learning and custom context, the Knowledge Base MCP, cross-repo context, and the team analytics dashboard are listed under Pro, not Starter.
CodeRabbit is the most widely deployed AI reviewer and, in one independent benchmark, produced far fewer false positives than Greptile, making it a better fit for teams that prioritize low noise over raw catch rate. Qodo Merge runs a multi-agent review architecture across GitHub, GitLab, Bitbucket, and Azure DevOps, useful for teams on platforms outside Greptile's self-serve plans. Cursor's BugBot is a flat-fee option built to flag only clear-cut bugs with minimal commentary, for teams that find AI review comments too noisy.
One independent benchmark (50 real pull requests across open-source projects including Sentry, Cal.com, and Grafana) found Greptile catching 82% of injected bugs versus CodeRabbit's 44%, because Greptile traces dependencies and git history across the whole repository rather than scanning only the diff. The same benchmark found Greptile producing 11 false positives to CodeRabbit's 2, and full-context reviews run several minutes instead of CodeRabbit's faster turnaround. Choose Greptile for complex, multi-service codebases where a missed bug is costly; choose CodeRabbit when review speed and low comment noise matter more.
Sign up at app.greptile.com and install the Greptile GitHub App, or connect a GitLab access token to a repository; the free Starter tier activates immediately with no card required. From there, add a .greptile.yaml file or plain-English review rules to scope what Greptile checks, and connect its MCP server to Claude Code, Cursor, VS Code, or Codex CLI to act on review comments inside the editor.
Greptile is an AI code review agent built by the San Francisco startup of the same name, founded in 2023 by Soohoon Choi, Vaishant Kameswaran, and Daksh Gupta and backed by Y Combinator's Winter 2024 batch. Rather than reviewing only the lines a pull request touches, it constructs a graph-based map of the whole repository, indexing functions, classes, import chains, and commit history before posting a single comment. Customers include PostHog, Retool, Klaviyo, Nvidia, Brex, Scale, and Zapier.
Its v4 review agent, released in March 2026, replaced a single-pass diff scan with a multi-hop reasoning loop that traces dependencies and git history across files before flagging an issue, and each comment carries a confidence score so developers can triage quickly. Greptile's own changelog reports the change lifted addressed-comments-per-PR 74%, and author reply and upvote rates rose alongside it, evidence the deeper context produces feedback developers actually act on.
Teams scope what gets reviewed through a .greptile.yaml configuration file, a linked markdown style guide, or rules written for specific paths in plain English, and Greptile adapts later reviews as it observes how a team responds, reacts, and commits over time. It installs as a GitHub App or GitLab integration and posts inline PR comments automatically. Newer surfaces listed on its site include TREX runtime validation (beta), a command-line client, and a security review feature, and a companion MCP server hands review data and custom context to editor-based agents so they can act on flagged issues in place. It fits scaling engineering teams on GitHub or GitLab willing to tune rules to manage noise in exchange for catching cross-module bugs; teams on Azure DevOps, or those wanting fast single-pass review, are better served elsewhere. Alternatives in the same space include CodeRabbit, Qodo, and GitHub Copilot, and the MCP server works with agents such as Cursor and Claude Code.
Pricing follows a free-plus-credits model: a no-cost Starter tier for a single developer, a Pro plan where teams buy credits with no seat fees and unlimited developers and agents, and custom enterprise terms that add self-hosted deployment, SSO/SAML, role-based access control, and support for GitHub Enterprise Server, GitLab Self-Managed, Bitbucket Data Center, and Gitea. Greptile is web-based, run through app.greptile.com and the GitHub/GitLab integrations, with no native desktop or mobile app.
In October 2026 Greptile announced a $50M Series B led by Menlo Ventures, which its announcement says values the company at $750M. It followed a $25M Series A in September 2025 led by Benchmark Capital and a $4.1M seed in June 2024 led by Initialized Capital. The company says it reviews more than 1% of all pull requests opened on GitHub each day. It is SOC 2 Type II compliant, with reports available to customers on request, and customer data is hard-deleted from production systems within a day of an admin-initiated request.
