Quick verdict
Bottom line up front: Greptile reviews pull requests with something most AI reviewers lack: a map of your entire codebase. Instead of judging a diff in isolation, it indexes how your code connects, then reviews changes against that context — the setup it credits for an 82% bug catch rate on its own benchmark. The trade is noise and metered pricing: Pro is $30 per seat per month with 50 credits included, and extra reviews cost $1 each. For large, tangled codebases, that trade can be worth it. For small, tidy repos, a flat-rate reviewer is cheaper and quieter.

What does Greptile do?
Greptile is an AI code-review service for GitHub and GitLab teams. It builds a graph index of your whole repository — files, dependencies, and how they call each other — and reviews each pull request against that full picture. A change that breaks something three modules away is exactly the class of bug a diff-only reviewer tends to miss, and the class Greptile is built to catch.
Its v4 release in 2026 added a deeper review mode (TREX reviews, at 3 credits instead of 1) and custom rules so teams can teach it their own patterns. Reviews arrive as pull-request comments your team accepts or dismisses, and that feedback shapes later reviews.
How much does Greptile cost?
| Plan | Price | What you get |
|---|---|---|
| Starter | $0 | 50 credits per month, one active developer, unlimited repositories |
| Pro | $30/seat/month | 50 credits included per seat, extra credits $1 each, custom rules and integrations; a seat is any developer who received a review that month |
| Enterprise | Custom | Self-hosting, SSO/SAML, GitHub Enterprise support, dedicated support |
Two discounts matter: qualifying open-source projects (MIT, Apache, or GPL) get Greptile free, and pre-Series A startups under $2 million in revenue get 50% off Pro, per published pricing summaries. Do the volume math before rollout: a standard review costs 1 credit, a TREX review 3, so a team merging hundreds of pull requests a month will pay real overage at $1 a credit.
What are Greptile’s strengths?
- Whole-codebase context: the repository graph catches cross-file breakage that diff-only reviewers structurally cannot see.
- High reported catch rate: 82% on the company’s own benchmark — treat it as a vendor claim, but the direction matches its architecture.
- A genuinely usable free tier: 50 credits a month for one developer on private work, not just a summary teaser.
- Custom rules and learning from feedback, so review style adapts to the team instead of staying generic.
- Startup and open-source discounts that cut the seat price in half or to zero for qualifying teams.
What are Greptile’s weaknesses?
- False positives: independent comparisons of the major reviewers found Greptile producing more false-positive comments than rivals — recall is bought with noise your team must triage.
- Metered pricing punishes volume: busy teams and heavy TREX use make the $1-per-credit overage a line item to forecast, not a rounding error.
- Platform limits: GitHub and GitLab are the story; Bitbucket and Azure DevOps teams should look elsewhere, per current comparisons.
- Depth is wasted on small repos: a five-file side project gains little from a codebase graph.
Who is Greptile for?
Mid-size and larger engineering teams on GitHub or GitLab whose reviews keep missing cross-cutting bugs — the refactor that silently breaks a distant caller. Solo developers can start free and will know within 50 credits whether the extra context finds bugs their current process misses.
Frequently asked questions
Is Greptile free?
There is a free Starter plan with 50 credits a month for one active developer, and free use for qualifying MIT, Apache, or GPL open-source projects.
How does Greptile pricing work?
Pro is $30 per seat per month including 50 credits per seat. A standard review costs 1 credit and a deeper TREX review costs 3; extra credits are $1 each.
How is Greptile different from CodeRabbit?
CodeRabbit prices flat per developer and is known for lower-noise reviews. Greptile indexes your entire codebase for deeper context, reports a higher catch rate, and meters reviews past the included credits.
Does Greptile support Bitbucket?
Current comparisons list GitHub and GitLab as its platforms, with no Bitbucket or Azure DevOps support — verify on its site if your stack depends on them.
Verdict
Greptile is the deep-context pick in AI code review. If your codebase is big enough that bugs hide in the connections between files, pay the $30 seat, watch the credit meter for a month, and judge it on bugs caught versus comments dismissed. If your repo is small and your reviews are already calm, a flat-rate rival will serve you for less fuss.
