Graphite is an AI code review platform for engineering teams. It combines stacked pull requests, AI reviews, and a merge queue in one workflow synced with GitHub.

Stacked pull requests - break large changes into sequenced smaller PRs to keep reviews moving.
AI reviews and chat - high-signal reviews on every PR with suggested fixes, plus a chat assistant for context and CI failures.
PR inbox - one review queue for the team's pull requests with notifications.
Merge queue - stack-aware merging that keeps branches green.
CLI and editor tooling - command line and VS Code extension for managing stacks, with CI optimization and dev metrics.

It is used by engineering teams at companies such as Shopify, Ramp, and Asana that review in small stacked changes instead of large pull requests.

Graphite offers a free 30-day trial with no credit card required.
