Graphite

Graphite builds a code review platform aimed at engineering teams working on GitHub. Its central proposition is a stacked diffs workflow: large changes are broken into smaller pull requests that can be reviewed and merged in sequence, so that one piece of work does not block others. The company reports that teams using the platform ship code three times faster and save hours per week on review cycles.

The product is delivered as an integrated set of tools. A command-line CLI manages stacks of diffs and pull requests, and a VS Code extension brings the same stack management into the editor. An AI code reviewer examines changes and flags bugs before merge, while merge queues automate the landing of changes in order to keep the main branch green. Dashboards track team velocity, giving engineering leads a view of how work moves through review.

The company's stated orientation is developer experience. Graphite integrates with GitHub and Git so that teams need not change the tools they already use, and it advocates replacing single large pull requests with smaller, reviewable units. The technical work spans developer tooling, AI-assisted code review, Git and GitHub integration, CLI and IDE extension development, merge queue automation and engineering velocity analytics.
