AI code review agent that indexes your whole repository as a graph and runs a swarm of parallel hypothesis-scoped agents over each PR, with TREX writing and running tests in a sandbox, auto-approve under a risk ceiling, and full self-hosting including air-gapped with your own models.

Greptile is an AI code review agent built on a simple premise: a reviewer should understand the whole codebase, not just the lines that changed. When a pull request opens, Greptile reviews it against a continuously updated graph of the entire repository, mapping how functions, classes, files and directories connect, so it catches problems diff-only tools are blind to, such as a change that breaks callers in files you did not touch.

Repo Clusters extend that further, giving reviews read-only access to up to seven related repositories so a change to a shared library is reviewed against the services that depend on it. Founded in 2023 by Daksh Gupta, Soohoon Choi and Vaishant Kameswaran, Greptile went through Y Combinator in W2024 and raised a $25M Series A led by Benchmark; it reports more than two thousand customers including Stripe, Amazon and Brex.

The review engine has moved fast. The v3 rewrite in late 2025 made it agentic, v4 in March 2026 raised addressed comments per pull request by 74 percent, and v5 in August 2026 replaced the single loop with a swarm of narrowly scoped agents running in parallel, each exploring one hypothesis for a potential bug, cutting median review time from just over five minutes to under two and a half while raising the share of comments authors act on from 52 to 66 percent. Each comment carries a confidence score and a P0 to P2 severity badge, reviews include summaries and auto-generated sequence diagrams, and Greptile replies in-thread to follow-up questions and pushback.

Two companion capabilities sit alongside review. TREX writes targeted tests for every pull request and runs them in an isolated sandbox against the repository's real services and framework rather than a mock environment, attaching logs, screenshots, traces or videos as evidence when something fails. A security reviewer chains Opengrep pattern scanning, dependency analysis against known vulnerability databases, and AI exploit detection for chained issues static tools miss, enabled by default.

Greptile learns. A named Memory and Learning system adapts from team pull request comments, replies to Greptile, thumbs up and down reactions, whether comments were addressed between first and last commit, and repeated patterns it converts into suggested custom rules. Teams also write rules explicitly, as structured JSON or plain markdown in a versioned .greptile/ folder with cascading inheritance from parent to child directories, scoped by file pattern with per-rule severity.

Oversight is configurable rather than assumed. Auto-approve lets Greptile approve only pull requests receiving a clean five-out-of-five review, under a customer-set ceiling on the highest risk it may approve, with exclusions by label, branch, file and author, and a hard never-approve list covering authentication, secrets, billing, database migrations, infrastructure, CI and public APIs.

The surface is broad: GitHub and GitLab including self-hosted instances behind a reverse proxy, context from Jira, Notion, Google Drive and Sentry, delivery into Slack, a hosted MCP server for Claude Code, Claude Desktop, Cursor and VS Code, a plugin in Anthropic's official marketplace, a REST API, an npm CLI with JSON and agent output modes, and Zapier. Fix with your Agent routes findings straight into Claude Code, Codex, Conductor, Cursor or Devin. A Partner Program supplies partner-maintained review context for OpenAI, Vercel, Stripe, PostHog, Datadog, WorkOS, Mintlify and Braintrust.

For regulated buyers the deployment story is unusually concrete: the whole service self-hosts via Docker Compose on a single VM up to 100 developers or Kubernetes above that, with an AWS Terraform module, manual setup for GCP, Azure or on-premises, a documented migration path between the two, a public deployment repository, air-gapped operation and customer-supplied LLM providers so code and inference never leave the network. Greptile is SOC 2 Type II certified with SAML SSO and audit logs.

Pricing is $30 per developer per month including 50 credits, then $1 per additional credit, a change made in March 2026 that drew criticism from high-volume and agentic workflows; Flex Usage Limits now let teams cap that overage spend in dollars. A free Starter tier for a single developer with 50 credits and unlimited repositories launched in June 2026, and open source projects qualify for free use. The site footer names the legal entity as Tabnam, Inc.

Integrations

Reviews pull requests in GitHub and GitLab across 30+ languages, including self-hosted GitLab behind a reverse proxy. Pulls context from Jira, Notion, Google Drive and Sentry; delivers findings to Slack and the IDE. Fix with your Agent routes a comment with file, line numbers and suggested fix straight to Claude Code, OpenAI Codex, Conductor, Cursor or Devin via a local bridge CLI, with a Fix All control. A hosted MCP server at api.greptile.com/mcp works in Claude Code, Claude Desktop, Cursor and VS Code; a Greptile plugin ships in Anthropic's official Claude Code marketplace. A REST API exposes Index Repository, Query Repos, Search Repos and Get Repository Info, plus webhooks and Zapier. An npm CLI runs reviews locally with JSON and agent output modes. The Partner Program adds maintained review context for OpenAI, Vercel, Stripe, PostHog, Datadog, WorkOS, Mintlify and Braintrust.

In practice

Your bugs hide across files, not in the diff. Greptile indexes your whole repository as a graph and reviews each pull request in that context, catching cross file breaks that diff only reviewers miss.

You are in a regulated industry and cannot send code to a SaaS reviewer. Greptile runs entirely inside your own cloud or an air gapped environment with your own models, so code never leaves your network.

A new engineer needs to understand an unfamiliar service. They ask Greptile in plain English how the authentication flow works and get an answer with references to the exact files, functions, and classes.

Workflow Orchestration Full

The v5 review engine runs a swarm of narrowly scoped agents in parallel, each exploring one hypothesis for a potential bug, with results aggregated into a single review; the vendor reports median review time falling from 5:04 to 2:25 and author-addressed comments rising from 52 to 66 percent in production A/B tests. The agent expands beyond the diff to find similar logic, traces dependencies, reads git history and runs iterative passes that challenge their own hypotheses, with the maximum number of agentic turns configurable per review; TREX runs as a companion agent writing and executing tests, and the security reviewer chains Opengrep pattern scanning, dependency analysis and AI exploit detection.

Knowledge Grounding & RAG Full

A graph index of the entire repository maps how functions, classes, files and directories connect and updates continuously, so reviews reason about ripple effects beyond the diff; Repo Clusters and a context.repos field give read-only access to related repositories during a review, up to seven per review, with clusters suggested from shared contributors over the previous 90 days; files.json points reviews at existing schemas, API specs and architecture docs in the repository; context is pulled from Jira, Notion, Google Drive and Sentry; the Partner Program supplies partner-maintained documentation for supported third-party APIs; and imported AI rules files including CLAUDE.md and Cursor rules become org-wide context. Developers query the codebase in natural language and receive answers referencing specific files, functions and classes.

Human Oversight & Guardrails Partial

Greptile posts its reviews and, where enabled, approves pull requests on its own under a customer set risk ceiling with exclusion filters and a never approve list covering authentication, secrets, billing, migrations, infrastructure, CI and public APIs, and custom rules shape what it flags. These are customer controlled constraints on the agent, and no step where a person approves the agent's action before it lands is documented.

Security, Identity & Governance Full

SOC 2 Type II certified with independent audits and data encrypted at rest and in transit, single sign-on with SAML documented as its own page in the self-hosting section, audit logs available to enterprise, and a dedicated security section covering compliance practices; the whole service self-hosts into a customer VPC or an air-gapped environment with customer-supplied LLM providers so code, secrets and inference never leave the network, and each sandbox and integration is scoped through the customer's own GitHub or GitLab installation. No trust portal, named audit firm or published attestation report has been found.

Observability & Auditability Partial

An analytics dashboard tracks pull requests reviewed, addressed rate, critical bugs caught, merge times and upvote to downvote ratios, filterable by team, repository, author and time period with export; each inline comment carries a confidence score and a P0 to P2 severity badge, review summaries include auto-generated sequence diagrams of call flows, and the review footer shows a review counter and a link to the last reviewed commit; enterprise deployments have audit logs, and TREX attaches execution evidence to failing findings. These report on review outcomes and team throughput rather than retaining a per-action trace of the agent's own reasoning, and no session record, execution replay or agent run history is documented.

Memory & State Persistence Partial

Memory and Learning is a named system that learns team preferences from PR comments, replies to Greptile, reactions and whether comments were addressed, and turns repeated patterns into suggested rules. The page states no scope boundary, lifetime or way to review and delete what was learned, so it meets Partial rather than Full.

Sourcegreptile.com/docs/how-greptile-works/memory-and-learningread 2026-09-29

Deployment & Data Residency Full

The entire service can be self-hosted, including in air-gapped environments, by Docker Compose on a single Linux VM for up to 100 developers or Kubernetes for 100 or more with horizontal scaling and high availability, with published sizing requirements and a documented migration path between the two via parallel deployments; an AWS Terraform module provisions VPC, EC2, RDS PostgreSQL and ElastiCache Redis and bootstraps the application, and manual setup covers GCP, Azure and on-premises.

The deployment repository is public at github.com/greptileai/akupara, self-hosting requires a license, custom LLM providers are supported so inference stays on customer infrastructure, and self-hosted GitLab behind a reverse proxy is supported. Cloud remains available for teams wanting no infrastructure management.

Prebuilt Agents, Templates & Packs Partial

The Partner Program supplies vendor-curated review context for third-party APIs, so a pull request touching a supported partner API, SDK, config or integration is reviewed against partner-maintained documentation, implementation rules and common failure patterns, with comments marked by partner logo and linked back to the relevant docs; it is enabled by default for all users with featured partners including OpenAI, Vercel, Stripe, PostHog, Datadog, WorkOS, Mintlify and Braintrust.

Greptile additionally ships two named agents, the code reviewer and TREX, and imports existing AI rules files including CLAUDE.md, AGENTS.md and Cursor rules as org-wide context. No browsable catalog, marketplace or gallery of installable agents or templates is documented.

Sourcegreptile.com/partners and greptile.com/changelog 2026-06-22read 2026-08-30

Triggers & Channel Coverage Full

Reviews start automatically when a pull request opens in GitHub or GitLab and re-run on later commits under configured review triggers, so work reaches the agent with no person starting it; it can also be invoked by @greptileai, a re-trigger control, a reply in the thread, or the CLI on a local branch.

Model Flexibility & Routing Full

Review settings let the customer choose which AI model powers reviews and set the maximum number of agentic turns per review, balancing speed, depth and cost; Model Inversion detects from commit trails, branch prefixes and PR titles when a pull request was authored by a coding agent and routes the review to a different model, so Claude-authored code is reviewed by GPT and GPT-authored code by Claude; and self-hosted deployments support custom LLM providers so models run entirely on customer infrastructure.

Testing, Debugging & Optimization Full

Testing the customer's change is the product: every pull request is reviewed for logic, security and cross file bugs with confidence scores and P0 to P2 severity, and TREX writes targeted tests for the change and runs them in a sandbox against the repository's own services, attaching logs and traces, which is a quality gate in the release path.

Browser & Computer Use Not documented

All documented action runs through programmatic interfaces: the GitHub and GitLab APIs for reviews, comments and approvals, a graph index of the repository, an isolated sandbox in which TREX executes generated tests against the repository's existing services and framework, a CLI, an MCP server and REST endpoints. TREX attaches logs, screenshots, traces, scripts or videos as evidence when a test fails, but no browser tool, computer-use capability or operation of software lacking a programmatic interface is documented on the TREX page, the agent page or in the changelog.

Pricing

Starter free (50 credits, 1 developer) · Pro $30/seat/mo (50 credits per seat, $1 per additional credit) · Enterprise custom · 14 day free trial

Per developer per month base subscription of $30 including fifty reviews, then $1 per additional review. Free for qualified open source projects. Enterprise is a custom annual or multi year contract, including self hosted deployment.

Free tierTrial available

Included quota

Developer: free for qualified open source projects licensed MIT, Apache, or GPL. Pro ($30/developer/mo): whole codebase aware review, 50 reviews per month included then $1 per additional review, 30 plus languages, custom rules, natural language codebase queries, and click to accept inline fixes. Enterprise (custom annual or multi year): self hosted and air gapped deployment, bring your own large language models, SSO and SAML, GitHub Enterprise compatibility, audit logs, dedicated Slack support, custom DPA and terms, and a higher security tier. SOC 2 Type II applies to all tiers. Pre Series A startups under $2 million revenue get 50 percent off Pro; annual contracts up to 20 percent off. 14 day free trial.

What is public

The per-developer rate and the overage mechanism are public: $30 per developer per month including 50 credits, then $1 per additional credit, reduced from $50 in May 2026. A free Starter tier is public (1 active developer, 50 credits per month, unlimited repositories), as is free use for qualifying open source projects and a 14-day trial. Flex Usage Limits allowing a dollar cap on overage spend are documented. Not public: self-hosted licensing and enterprise pricing, both quoted through sales.

Billing mechanics

$30 per developer per month base including fifty credits, then $1 per credit, billed to the account. Free for qualified open source. Enterprise is a custom annual or multi year contract with self hosting. 14 day trial, no credit card.

Cost watchouts

Reviews beyond the 50 included per active developer per billing period are billed as flex reviews at $1 each, which drew significant criticism in March 2026 from teams running agentic workflows: at the vendor's own stated average of 1.2 reviews per pull request, 50 reviews covers roughly 42 PRs per developer per month, and one reported case saw a bill rise from $30 to over $500. Flex Usage Limits, shipped 30 April 2026, now let a customer set a dollar cap on flex spend, after which new flex reviews are skipped until the next billing period while included reviews continue. Self-hosting requires a separate license quoted by the vendor.

Variable cost rationale

The base is a predictable $30 per developer per month, but it includes only fifty reviews, after which each review costs $1 with no cap. Greptile says fewer than ten percent of users exceed the quota, but high throughput and agentic workflows blow past it fast, with reviewers reporting bills climbing to several hundred dollars per seat at a few hundred pull requests a month. Exposure is high for modern high volume and agent driven teams and low for teams comfortably under the quota.

Additional watchouts

The $1 per credit overage above fifty can escalate cost sharply for high volume or agentic workflows. Coverage is limited to GitHub and GitLab, with no Bitbucket or Azure DevOps. Higher false positive rate than quieter competitors. No in app cancel button reported. Open source maintainers have reported being billed despite the free open source policy.

Overage / add-ons

The Pro plan includes fifty reviews per developer per month; each review beyond that costs $1. One standard review uses one credit and the average pull request consumes roughly one to one point two reviews. There is no cap, so high volume or agentic workflows can accrue significant overage.

Sales call required

No, self serve available

Free / trial

Free Starter tier for individual developers, launched 29 June 2026: 1 active developer, 50 credits per month, unlimited repositories, no team creation. Open source projects also qualify for free use. 14-day free trial on paid plans.

Lowest paid plan

Pro at $30 per developer per month, including fifty code reviews per month with additional reviews at $1 each, covering whole codebase aware review across GitHub and GitLab with thirty plus languages and click to accept fixes.

Commercial notes

Positioned as the highest catch rate reviewer through whole codebase indexing, priced at a modest base with usage overage. Value is highest for teams with large complex codebases where cross file bugs are costly, and for regulated enterprises that need air gapped self hosting with their own models. The usage overage makes it expensive for high throughput and agentic teams, where flat priced competitors such as CodeRabbit or Cursor BugBot are cheaper.

Key ambiguities

The unit of sale has moved from reviews to credits: the pricing page counts 50 credits per seat and $1 per additional credit, while earlier changelog entries describe 50 reviews and a flex review model, so how credits map to reviews and re-reviews is not spelled out. Whether the general free tier and the open source free plan are the same thing is not stated. Self-hosted and enterprise pricing is quoted rather than published.

Cancellation / refund

Pro is a self serve monthly subscription that can be canceled through account settings, though reviewers note there is no in app cancel button and cancellation may require contacting support. Enterprise is a custom annual or multi year commitment. Open source maintainers have reported being billed despite the free open source policy, resolved case by case.

Support SLA / resale

SOC 2 Type II certified across all tiers with independent audits and reports available on request; encryption at rest and in transit. Enterprise adds SSO and SAML, audit logs, a dedicated Slack support channel, custom DPA and terms, and self hosted or air gapped deployment. No public reseller or white label program surfaced.

Missing data

Enterprise and self hosted pricing are custom and not public beyond a reported AWS Marketplace floor. The exact economics at high review volume depend on team specific pull request and re review patterns.
