Graphite is a code review platform built around GitHub. Its signature feature is stacked pull requests, which break a large change into small, sequenced pull requests so that work continues while earlier ones are under review. A command line tool and a VS Code extension create and manage the stacks and wrap everyday git commands, and a stack-aware merge queue lands the pull requests in order.

Graphite also provides a new pull request page, a unified inbox for the team's reviews, Slack notifications, insights on team review activity, CI optimization and AI features. Graphite Chat is an assistant on the PR page that can explain changes, fix CI failures and apply suggested fixes, and AI Reviews comment on each pull request with suggested fixes. The site notes that Cursor cloud agents are now available inside Graphite.
The pricing page lists Hobby as free for personal account repositories, with limited AI reviews and limited chat. Starter is $20 per user per month, billed annually, and covers all GitHub organization repositories with Slack notifications and team insights. Team is $40 per user per month, billed annually, with unlimited chat, unlimited AI reviews, review customizations, automations and a merge queue. Enterprise is custom and adds SAML, audit logs, GitHub Enterprise Server support and service level agreements.
