Graphite

What is Graphite?

Graphite is an open source code review tool designed to streamline the pull request workflow on GitHub. It enables developers to work with stacked PRs—a branching strategy where multiple related pull requests are organized in a dependent sequence—allowing teams to break down larger changes into smaller, more reviewable units. The tool addresses common bottlenecks in traditional code review by making it easier to create, manage, and review chains of related pull requests. Rather than waiting for one PR to merge before starting the next, developers can stack changes and get feedback in parallel, potentially reducing the time from initial commit to merged code. Graphite is built for engineering teams looking to improve code review efficiency and software quality on GitHub. It's particularly useful for teams that work on interconnected features or refactors where changes naturally depend on one another. As an open source project, Graphite can be self-hosted and integrated into existing development workflows without vendor lock-in. The tool focuses on providing practical utilities for managing the stacked PR pattern, helping teams adopt this methodology without requiring significant process changes or additional tooling overhead.
