Graphite is an AI developer productivity platform built around stacked pull requests and intelligent code review. Founded by engineers from Meta and Google who experienced the benefits of internal tools like Phabricator and Critique, Graphite brings that same structured review workflow to every engineering team using GitHub.
The core innovation is the stacked PR workflow. Instead of creating one massive pull request, developers break changes into small, dependent PRs that form a logical sequence. Each change builds on the previous one, and when an earlier PR merges, subsequent changes are automatically rebased. This approach keeps developers unblocked — you can continue working on PR #3 while PR #1 and #2 are still under review.
Graphite Agent is the platform's AI code review companion that goes beyond leaving comments. It helps developers act on feedback by fixing issues, updating PRs, and merging code collaboratively. The agent maintains an unhelpful comment rate under 3%, and when it flags an issue, developers change the code 55% of the time compared to 49% for human reviewers. It can also resolve CI failures inline and suggest concrete fixes.
The stack-aware merge queue coordinates landing changes in the correct order, testing multiple PRs in parallel rather than sequentially. This reduces wait times and keeps branches green. Teams can define custom review standards in plain language, and the AI enforces them automatically across every pull request.
Enterprise adoption has shown strong results. Shopify reported 33% more PRs merged per developer after adoption, with 75% of PRs going through Graphite. Asana saw engineers save 7 hours weekly, ship 21% more code, and cut median PR size by 11%. These improvements come from combining stacked workflows with AI-assisted review.
The platform includes a modern PR review interface with a unified inbox, actionable Slack notifications, a powerful CLI for managing stacks from the terminal, and a VS Code extension for in-editor workflow. Graphite takes a privacy-first approach, guaranteeing that code stays private and is not used for model training.
Pricing includes a free Hobby tier with CLI access and limited AI reviews, a Starter plan at $20/user/month with full organization support, and a Team plan at $40/user/month with unlimited AI agent access, review customizations, automations, and merge queue. All plans include a 30-day free trial.
Graphite is best suited for teams where the review process itself is the bottleneck. The stacked PR paradigm requires team-wide adoption for maximum benefit, making it a stronger fit for organizations ready to commit to a workflow transformation rather than just adding an AI reviewer on top of existing practices.
