Graphite

Graphite is a modern code review and change management platform that combines stacked pull requests with AI-enhanced review capabilities, designed for fast-moving engineering teams. It reimagines the PR workflow by enabling developers to stack dependent changes on top of each other rather than waiting for sequential reviews, dramatically reducing merge queue bottlenecks.

The stacked PR workflow allows developers to keep building while earlier changes are under review. Graphite manages the complexity of rebasing and updating dependent PRs automatically. When a base PR is merged, all stacked PRs are rebased and updated without manual intervention. This approach, popularized internally by companies like Google and Meta, is made accessible to any team using GitHub through Graphite's CLI and web dashboard.

Graphite's AI features include automated PR descriptions, intelligent review summaries, AI-powered code review that identifies bugs and suggests improvements, and smart reviewer assignment. The platform also provides a merge queue that runs CI checks and manages dependencies, ensuring only passing code reaches the main branch. Analytics dashboards track review velocity, merge times, and team productivity metrics.

Used by engineering teams at companies including Snowflake, Notion, Ramp, Figma, and Vercel, Graphite has established itself as the leading stacked PR platform. The combination of workflow optimization and AI review makes it particularly effective for teams that ship frequently and want to minimize the time code spends waiting for review.
