Greptile
FreemiumAI code review with full-codebase context.
Published 27 September 2026
Scores
Popularity3/5
Established
Well regarded among teams evaluating AI code review, with more than 2,000 customers and Benchmark backing, but far less widely known than CodeRabbit and largely unknown to developers outside that decision.
Learning Curve2/5
Easy
Connecting a Git host and indexing a repository is quick, but getting the most out of it means writing custom rules and understanding the credit model and when a TREX review is worth three credits.
Flexibility4/5
Flexible
Plain-language custom rules, a choice of standard or execution-backed reviews, an API, and on Enterprise a bring-your-own-model option give teams real control over how reviews run.
Performance4/5
Fast
Independent comparisons put its raw bug-catch rate at the top of the mainstream AI reviewers, driven by the codebase graph, and TREX adds execution evidence that static reading cannot produce.
Portability4/5
Portable
Supports GitHub, GitLab, and Bitbucket in the cloud and can be self-hosted or run air-gapped with a team's own models on Enterprise, which few rivals offer. Azure DevOps is the notable gap.
About Greptile
Greptile reviews pull requests using an index of the entire codebase rather than the diff alone. It builds a graph of the repository's functions, classes, and dependencies, and when a pull request opens it traces which callers and modules the change affects, checks git history for related changes, and posts line-level comments with a confidence score for each finding. Teams can add custom review rules in plain language, and the reviewer adjusts to which of its comments get addressed or dismissed.
A second review mode, TREX, goes past reading code: it runs the change in a sandbox and attaches logs, screenshots, API traces, or video to the review as evidence for what it found. Reviews on paid plans are metered in credits, with a standard review costing one credit and a TREX review three, so heavier validation is something a team opts into per pull request rather than paying for on every change.
Greptile connects to GitHub, GitLab, and Bitbucket, and the Enterprise plan adds self-hosted and air-gapped deployment, bring-your-own language models, SSO, and support for GitHub Enterprise Server, GitLab Self-Managed, Bitbucket Data Center, and Gitea. The Y Combinator company raised a Benchmark-led Series A and counts Brex, Substack, PostHog, and Whoop among more than 2,000 customers.

Tools Related to Greptile
Integrates with Greptile(2)
Greptile connects as a GitHub App to review pull requests, commenting on the diff with findings ranked by its index of the whole codebase.
Greptile reviews GitLab merge requests natively, with the same whole-repo indexing and comment findings as its GitHub integration.
Alternatives to Greptile(2)
Greptile indexes the entire codebase for review context and can be self-hosted; CodeRabbit counters with wider Git-host coverage and a free OSS tier — depth and control against breadth.
Greptile reviews merge requests from any workflow with whole-repo context and a self-hosting option, while Cursor Bugbot targets bugs specifically and bills per review through a Cursor account.
