AI code review and pull request platform built around stacked PRs, a stack-aware merge queue and Graphite Agent, which reviews, chats, applies fixes and merges; now owned by Cursor with Cursor Cloud Agents surfaced inside the PR.

Graphite is an AI powered code review and pull request platform built for the outer loop of software development, the reviewing, merging, and shipping that becomes the bottleneck as AI accelerates code generation.

Its signature idea is stacked pull requests, a workflow borrowed from Meta and Google in which a large change is broken into a chain of small dependent pull requests, each reviewed and merged on its own, so a developer can keep working up the stack while earlier parts are still in review. A command line tool and a VS Code extension handle the stacking and automatically rebase the stack as changes land.

Founded in 2020 by Merrill Lutsky, Greg Foster, and Tomas Reimers, Graphite was acquired by Anysphere, the maker of Cursor, in December 2025, and continues to operate as its own product.

The AI layer, first launched as Diamond and now unified with chat under the name Graphite Agent, reviews every pull request in seconds with high signal feedback rather than noise. It catches real bugs, logic errors, style inconsistencies, and security issues in the context of the whole codebase, and teams report it surfacing problems that human reviewers and CI both miss.

Graphite Agent goes past commenting: developers chat with it in the pull request to ask questions, refine suggestions, and apply fixes conversationally, taking a change from feedback to commit in one flow. Teams import their own style guide and write rules in plain English, and its feedback is tuned continuously against whether developers accept or reject each comment.

Around the reviewer sits a full workflow platform. A stack aware merge queue organizes approved pull requests to keep the trunk branch green, CI optimizations integrated with Buildkite and GitHub Actions let teams selectively trigger and batch test runs, and a pull request inbox centralizes reviews. Developer productivity insights give engineering leaders analytics on throughput and cycle time, and a workflow automation engine automates parts of review and merge. Graphite plugs into GitHub repositories and pipelines, works in VS Code and the command line, and now surfaces Cursor cloud agents inside the pull request so code can be created, reviewed, and shipped without leaving the page.

Graphite is SOC 2 Type II certified, continuously penetration tested, and its AI features are opt in and do not train on customer code. Its main constraints are that it centers on GitHub and is delivered as hosted software with no self host option, it offers no user facing model choice and no public API to build on, and the stacked workflow has a learning curve.

Pricing simplified in early 2026: a free Hobby tier with the stacking command line tool, the VS Code extension, and limited AI reviews, a Starter plan at twenty dollars per user each month billed annually, a most popular Team plan at forty dollars per user each month that unlocks unlimited Graphite Agent reviews and chat, the merge queue, and automations, and a custom Enterprise plan, each with a thirty day free trial and no credit card.

Funding status

Acquired, and now two levels up a chain. Graphite was founded in March 2020 by Merrill Lutsky (CEO), Greg Foster (CTO) and Tomas Reimers (CPO), raising $72M across a $20M Series A led by Andreessen Horowitz and a $52M Series B led by Accel at a $290M valuation, with Menlo Ventures participating through the Anthology Fund. Anysphere, maker of Cursor, announced its acquisition in December 2025 at a price reported well above that valuation. Anysphere itself was then acquired by SpaceX: an all-stock merger signed 16 June 2026 that formally closed on 14 August 2026, converting Anysphere into a SpaceXAI division. Graphite continues to operate as its own product and brand, with contact and sales routed through cursor.com. Reported at 100,000+ engineers across 500+ companies including Shopify, Snowflake, Figma, Asana, Ramp, Vercel and Perplexity.

Integrations

Deep GitHub integration across repositories, pull requests, CI and merge, with GitHub Enterprise Server supported on Enterprise. Surfaces are a CLI for stacked PRs and simplified git commands, a VS Code extension, an MCP server, the web PR page and a PR inbox, all available from the free tier. Slack notifications ship from Starter with advanced integrations on Team. The CI optimizer integrates Buildkite and GitHub Actions to selectively trigger and batch test runs. Following the acquisition, Cursor Cloud Agents are surfaced inside the Graphite pull request so code can be created, reviewed and shipped without leaving the page. Graphite Agent acts by commenting inline, applying suggested fixes, generating PR titles and descriptions, summarizing CI failures, rebasing stacks and merging through a stack-aware merge queue.

In practice

Your large changes sit in review too long and block the team. Graphite lets you split them into a stack of small dependent pull requests, each reviewed and merged on its own while you keep building.

AI is generating more code than your reviewers can keep up with. Graphite Agent reviews every pull request in seconds, flags real bugs and security issues in context, and lets you apply fixes in chat.

Your trunk keeps breaking and merges pile up. Graphite's stack aware merge queue sequences approved pull requests and batches CI so the main branch stays green without engineers babysitting the merge order.

Workflow Orchestration Full

A stack-aware merge queue sequences approved pull requests to keep the trunk branch green, offered as Basic on Team and Advanced with additional settings on Enterprise, and automatically rebases stacked branches as earlier changes land so a chain of dependent pull requests stays current without manual intervention; an Automations engine and a CI optimizer batch and selectively trigger test runs, integrated with Buildkite and GitHub Actions, and Graphite Agent chains review into suggested fixes, CI summaries and collaborative merge within the pull request.

Sourcegraphite.com/pricing and graphite.com/featuresread 2026-08-30

Knowledge Grounding & RAG Partial

Optional code indexing, which Graphite describes as indexing code for short periods of time, speeds Graphite Chat's tool calls and the PR page, while reviews referencing related files through the index are marked coming soon; by default Graphite stores no code and reads it from GitHub, and style guides and rules are instructions, so a maintained retrieval structure grounding the agent's reviews is not yet shipped.

Sourcegraphite.com/docs/code-indexing and docs/ai-review-customizationread 2026-09-29

Human Oversight & Guardrails Partial

Review output is advisory: findings land as inline comments and suggested fixes a developer chooses to apply, and Graphite Chat lets the developer interrogate and refine a suggestion before committing, with the human accountable for the merge; teams constrain the reviewer through AI review customization covering automations, filters and rules and an imported style guide, the merge queue gates what reaches trunk under team-configured rules with advanced settings on Enterprise, and ACLs on Enterprise bound access. No per-action approval gate on agent actions, permission scoping for the agent itself or shadow mode is documented.

Sourcegraphite.com/pricing and graphite.com/featuresread 2026-08-30

Security, Identity & Governance Full

The Enterprise plan documents SAML and SSO, access control lists, an audit log with SIEM export, GitHub Enterprise Server support, custom MSA and private uploads, while code indexing controls and AI privacy controls are listed as admin capabilities in the plan comparison; the vendor states it is SOC 2 Type II certified and continuously penetration tested, and that AI features are opt in and do not train on customer code.

Sourcegraphite.com/pricing and graphite.com/docs/privacy-and-securityread 2026-08-30

Observability & Auditability Partial

Team insights ship from Starter with custom analytics on Enterprise, giving engineering leaders throughput and cycle-time reporting, and an audit log with SIEM export is available on Enterprise; a PR inbox centralizes reviews, review findings persist as durable inline comments on the pull request, and CI summaries explain failures in place. These report on team throughput and account access rather than retaining a per-action trace of the reviewer's own reasoning, and no agent execution record, session history or replay surface is documented.

Sourcegraphite.com/pricingread 2026-08-30

Memory & State Persistence Not documented

Review quality is tuned continuously from whether developers accept or reject each comment, and teams import a style guide and author rules the reviewer applies on every pull request, but both are model tuning and static configuration rather than state accumulating across sessions; code indexing persists a representation of the repository under admin controls, which is grounding infrastructure rather than agent memory. No named memory feature, conversation persistence or cross-session state mechanism is documented on the pricing matrix, in the features navigation or on the homepage.

Sourcegraphite.com/pricing and graphite.com/featuresread 2026-08-30

Deployment & Data Residency Not documented

Delivered as hosted software through a GitHub app with a CLI and VS Code extension as clients; the Enterprise tier adds GitHub Enterprise Server support and private uploads, which extend compatibility to a customer-hosted code host rather than allowing Graphite itself to run in the customer's environment. No self-hosted, on-premises, VPC, private instance or customer-selectable region option is documented on any tier including Enterprise, where such an option would be listed alongside SAML, ACLs and audit export.

Sourcegraphite.com/pricingread 2026-08-30

Prebuilt Agents, Templates & Packs Not documented

A single Graphite Agent ships as the reviewer, configured per team through AI review customization covering automations, filters and rules and an imported style guide written in plain English; these are customer-authored configuration rather than vendor-supplied assets. No library of prebuilt agents, template gallery, rule pack, starter set or agent marketplace is documented on the pricing matrix, in the features navigation or on the homepage.

Sourcegraphite.com/pricing and graphite.com/featuresread 2026-08-30

Triggers & Channel Coverage Full

Graphite Agent reviews every pull request automatically when it is opened or updated, and automations act on pull request events to assign reviewers and add labels, so work reaches the agent with no person starting it; developers also reach it from the PR page, Graphite Chat, the CLI, VS Code and MCP.

Model Flexibility & Routing Partial

Graphite discloses that its AI features run on models from Anthropic and OpenAI, its two AI subprocessors, and keeps the choice itself: no model picker, routing setting or bring your own key path is documented.

Sourcegraphite.com/docs/ai-privacy-and-security and graphite.com/pricingread 2026-09-29

APIs, SDKs & MCP Extensibility Partial

MCP is listed as a shipped feature on every plan including the free Hobby tier, grouped with the CLI and VS Code extension under stacking capabilities, so external agents can drive Graphite's stacked pull request operations; the CLI itself is a substantial client for stack management and simplified git commands, and the vendor publishes source on GitHub under the withgraphite organization. No public REST API, SDK or webhook surface for building on the Graphite platform is documented.

Sourcegraphite.com/pricingread 2026-08-30

Testing, Debugging & Optimization Full

Testing the customer's change is the product: AI reviews check every pull request for bugs, logic errors and security issues before merge, with suggested fixes, CI summaries and team tuned rules, a quality gate in the release path that lets the customer test its own work.

Browser & Computer Use Not documented

Every documented action runs through programmatic interfaces: the GitHub API for pull requests, comments, suggested fixes and merges, git for stacking and automatic rebasing, the CLI, the VS Code extension, MCP, and CI integrations with Buildkite and GitHub Actions. No browser control, screenshot capture, visual verification or capability to operate software lacking a programmatic interface is documented.

What is public

All three named tier prices are published exactly on a per-user basis with annual billing at 20 percent off: Hobby free, Starter $20/user/month, Team $40/user/month, Enterprise custom. A full plan comparison matrix publishes per-tier entitlements across pull requests, stacking, Graphite Chat, team features and admin controls, including which tiers carry SAML/SSO, ACLs, SIEM audit log, GHES and custom analytics. A 30-day free trial with no credit card is offered. Only Enterprise pricing is quote-based, routed through cursor.com/contact-sales.

Billing mechanics

Per user per month subscription billed annually across three self serve tiers plus custom Enterprise. Team is the unlimited AI tier. Free tier and a 30 day no credit card trial on all plans.

Cost watchouts

Cost scales with the number of user seats on the Team tier; unlimited AI reviews avoid per review surprises. Annual billing is required for the listed per user prices. Enterprise pricing is quote based.

Variable cost rationale

Pricing is a predictable per user monthly subscription, and the most popular Team plan includes unlimited Graphite Agent reviews and chat with no per review metering, so spend scales with seat count and tier rather than usage. The main step is choosing Team for unlimited AI. Exposure is low: bounded per seat with no usage overage.

Additional watchouts

Centered on GitHub with no support for other Git hosts. Delivered as hosted software with no self host or data residency option. No user facing model choice. The stacked pull request workflow has a learning curve, and some users dislike the diff and comment panel layout. As an Anysphere property, the longer term roadmap may fold into Cursor's platform.

Overage / add-ons

No per review or usage overage on the Team tier, which is unlimited for AI reviews and chat. Cost changes come from adding user seats or moving between tiers rather than metered usage.

Sales call required

No, self serve available

Free / trial

Free Hobby tier includes the stacking command line tool, the VS Code extension, and a limited amount of Graphite Agent AI review. Every paid plan includes a 30 day free trial that does not require a credit card.

Lowest paid plan

Starter at $20 per user per month billed annually: support for all GitHub organization repositories and team insights, on top of the free stacking command line tool and VS Code extension.

Commercial notes

Repriced in early 2026 to bring AI reviews, stacking, and the merge queue into one Team plan at $40 per user, positioned against Cursor BugBot at the same price. Now owned by Anysphere, so expect tighter Cursor integration over time. Value is highest for high velocity GitHub teams that want the stacked pull request workflow plus AI review in one platform.

Key ambiguities

Tier prices and per-tier entitlements are fully published, so the main open question is not price but ownership trajectory: Graphite is now two levels down a chain, acquired by Anysphere/Cursor in December 2025 and by SpaceX through the Anysphere merger that closed 14 August 2026. Enterprise sales and contact are already routed through cursor.com, and Cursor's Origin platform natively carries Graphite's stacked pull requests, so packaging may change. The pricing page's canonical and Open Graph tags point at a staging Vercel URL rather than graphite.com, which is cosmetic but indicates the page is served from a staging deployment.

Cancellation / refund

Self serve monthly plans billed annually, with a 30 day free trial and no credit card to start. Enterprise via custom agreement. Specific cancellation and refund terms are not detailed.

Support SLA / resale

SOC 2 Type II certified with continuous penetration testing; report available from the security team. AI features are opt in and do not train on customer code. Enterprise adds advanced controls and support. No public reseller or white label program surfaced.

Missing data

Enterprise pricing is custom and not itemized. Post acquisition changes to packaging or bundling with Cursor are not yet public. Exact limits of the free tier AI reviews are not specified.
