Graphite is an AI-powered code review platform built around Git/GitHub workflows that combines an AI reviewer, a stacked-PR workflow, and a merge queue so engineering teams can review and ship smaller changes faster, built by Graphite.
Who builds it
Graphite is a developer-tools company whose product grew out of the "stacked diffs" workflow used at large engineering organizations, adapted for teams on GitHub. It integrates directly with GitHub via a deep sync integration rather than requiring a separate git host.
Core features
- AI code review: an AI reviewer scans pull requests to catch bugs and suggest fixes before merge, aiming for high-signal comments over noisy nitpicks.
- Graphite Chat: gives developers instant context on a piece of code or help resolving a failing CI run without leaving the PR.
- Stacked PRs: breaks larger changes into smaller, sequenced pull requests so teams can keep shipping while earlier PRs in the stack are still under review.
- Stack-aware merge queue: lands PRs in the correct order while keeping the target branch green, reducing merge conflicts and review bottlenecks.
- Unified PR inbox: a single view for a team's open pull requests to coordinate review load.
- CLI and VS Code extension: for managing stacks and PRs without leaving the editor or terminal.
- Slack notifications and CI optimization that runs tests strategically rather than the full suite on every push.
Pricing
- Hobby (Free): personal-account repositories only, limited AI Reviews and Chat usage, includes the PR inbox, CLI, VS Code extension, and MCP access.
- Starter: $20/user/month (billed annually) — adds support for all repositories in a GitHub organization, Slack notifications, and team insights, on top of everything in Hobby.
- Team: $40/user/month (billed annually), Graphite's most popular tier — unlimited AI Reviews and Chat, the stack-aware merge queue, automations, suggested fixes, and AI review customization, on top of everything in Starter.
- Enterprise: custom pricing — adds SAML SSO, access control lists, audit logs, GitHub Enterprise Server (GHES) support, and premium SLAs.
A 30-day free trial is available with no credit card required.
Who it's for
Engineering teams on GitHub who want to increase shipping velocity without sacrificing review quality — particularly teams that already use, or want to adopt, a stacked-PR workflow to keep changes small and reviewable. Customers referenced by Graphite include Semgrep, Shopify, Ramp, Asana, and Tecton, suggesting a fit for both fast-moving startups and larger organizations that need a stack-aware merge queue to manage high PR volume.
