Greptile
Hosted AI code reviewer that comments on pull requests, with security scanning and optional end-to-end test runs.
What is Greptile?
Greptile is a hosted AI code reviewer. It indexes your repository into a graph of functions, classes and dependencies, then comments on each pull request with findings and suggested fixes. It supports GitHub, GitLab and Bitbucket (cloud and self-managed), plus Gitea and Perforce. Security review (Opengrep rules, dependency checks and an AI agent) has been on by default since July 2026. TREX, generally available since 16 October 2026, starts your app in a sandbox, clicks through the flows a change touches and posts a video of each.
Greptile is a closed-source, venture-backed company. Only its CLI (npm `greptile`, MIT) is public; the PyPI package named `greptile` is unrelated. It bills in prepaid credits at $1 each with no seat fees: Base reviews cost 1 credit, Plus 3, Apex 10, and a TREX run 3 more. Self-hosting is Enterprise only.
On 19 October 2026 it raised a $50M Series B led by Menlo Ventures at a $750M valuation. As of 15 November 2026 its main rivals are CodeRabbit and the reviewers built into GitHub Copilot and Claude Code.
Our review
3.5A good fit for teams that want one dedicated PR reviewer across GitHub, GitLab and Bitbucket and would rather pay per review than per seat. Its feature set (whole-repo context, security scanning on by default, TREX end-to-end runs) goes further than the reviewers bundled with Copilot or Claude Code. Two things hold it back: evidence and predictability. We haven't run it on our own repositories, public discussion in the last 90 days is thin, and benchmark wins are mostly vendor-reported. With Auto tiers, push reviews and TREX, the monthly bill is also hard to forecast.
Pros
- + Works across GitHub, GitLab, Bitbucket, Gitea and Perforce, cloud or self-managed
- + No seat fees: $1 credits are shared across the org, so occasional contributors cost nothing until they open a PR
- + Security review is on by default, and TREX can run your app and attach a video of each tested flow
Cons
- − Cost moves with PR volume, review tier and triggers, and reviews pause when prepaid credits run out
- − Closed source; self-hosting is Enterprise-only, and the self-hosted Kubernetes worker must run privileged
- − Little independent evidence yet: thin community discussion, and benchmark claims come mostly from vendors

Should you use Greptile?
A good fit if you're…
- Teams on GitLab, Bitbucket or a mix of hosts who want one PR reviewer everywhere; Claude Code's hosted review is GitHub-only
- Organizations with many occasional contributors (contractors, part-timers), where per-seat review pricing wastes money
- Companies that need code review to run on their own infrastructure, including air-gapped (Enterprise self-hosting)
- Web-app teams who want PRs exercised end to end (TREX) and are willing to script an environment for it
Probably not for you if you're…
- Solo developers who want free local reviews before pushing: the CLI isn't on the free Starter plan
- Teams that need a fixed, predictable monthly bill
- Teams already paying for Copilot Business or Enterprise who only want occasional PR review
Pick something else if…
- you already pay for Copilot seats and want PR review on GitHub billed from the same AI-credit allowance (GitHub estimates about $0.25–$1.50 per review at the Lite and Balanced levels) → GitHub Copilot
- you want to run reviews yourself with /code-review or in your own GitHub Actions or GitLab CI, or you're on a Claude Team or Enterprise plan with GitHub repos → Claude Code
- you'd rather have a fixed per-developer bill, need Azure DevOps support, or want the same reviewer in your editor and CLI; trial both on the same repositories → CodeRabbit
Gotchas to know before you commit
- Reviews stop when prepaid credits run out ('new reviews pause until you add more'), so turn on automatic recharge or PRs can merge unreviewed.
- With the Auto tier you pay for the tier that ran (1, 3 or 10 credits). Tier rules such as Apex on PRs into main multiply cost, and an '@greptileai review this at apex' comment raises the tier for that review.
- By default Greptile reviews a PR once, when it opens (autoReview: ["open"]). Adding 'push' re-reviews every new commit, and each review is charged; TREX's automatic runs follow the same events.
- TREX needs a working environment (setup script, build variables, network access) before it can test anything. Plan setup time, not just credits.
- Name collision: `pip install greptile` installs an unrelated grep tool. The CLI is npm `greptile` or `brew install greptileai/tap/greptile`, and needs Node 22+.
Greptile pricing
Prepaid credits at $1 each, shared across the organization, with no seat fees: a review spends 1, 3 or 10 credits depending on tier, and a TREX run adds 3. Cost follows PR volume rather than headcount, so it climbs fast once you review every push, use Plus or Apex widely, or run TREX on every PR.
- 50 credits per month
- Unlimited repositories
- Limit: 1 active developer, no team creation
- Limit: CLI reviews not included
- Unlimited developers, no seat fees
- Base 1 credit, Plus 3, Apex 10, TREX +3
- Cross-repo context; Jira, Linear and Notion integrations
- 14-day free trial
- Limit: New reviews pause when the balance hits zero (automatic recharge is optional)
- Self-hosting (Docker Compose or Kubernetes)
- SSO/SAML, role-based access
- Limit: Sales quote only; you supply LLM provider keys when self-hosting
- Free use, by application
- Limit: Approval required; commercial projects don't qualify
What it costs in practice
| Solo developer | $0 Starter: up to 50 Base reviews a month (50 credits × 1). No CLI reviews on this plan. |
|---|---|
| Team of 10, ~200 PRs/month | ~$200–350 / month Default triggers review each PR once, when it opens. All Base: 200 × 1 = 200 credits = $200. Greptile doesn't publish how Auto splits tiers, so the upper figure assumes 80% Base, 15% Plus and 5% Apex: 160 + 90 + 100 = 350 credits = $350. Seat count doesn't change this. |
| Same team, reviews on every push + TREX | up to ~$2,400 / month Assumes 3 reviewed pushes per PR: 200 × 3 = 600 Base reviews = $600. TREX on each review adds 600 × 3 = 1,800 credits = $1,800, but it's charged only when a flow passes or fails, and skipped when nothing is testable. |
