Summary
Stacked pull requests plus AI review — a workflow built around small, fast-moving changes.
Description
Graphite started as the tooling that makes stacked pull requests practical on GitHub and has grown into a full code review platform with AI at its centre.
Stacking
Instead of one large PR, you break work into a stack of small dependent PRs. Each is reviewable in minutes, and Graphite handles the painful parts — rebasing the whole stack when the base moves, merging in order, and keeping the GitHub UI coherent. The CLI (gt) makes creating and restacking branches a single command.
AI review
Diamond is Graphite's reviewer. It comments on pull requests with a deliberately high signal threshold, catching logic errors and codebase-inconsistent changes, and it can generate fixes. Because Graphite already understands the stack, review comments land on the specific PR that introduced the problem rather than on a merged blob.
The rest
- A review inbox that replaces GitHub's notification firehose with a prioritised queue
- Merge queues that keep the main branch green
- Insights on review latency and PR size, which is where most teams find their real bottleneck
Free for individuals and small teams, paid per seat above that.
