Graphite — Technical Overview
Graphite is a freemium code review platform (founded 2021) built to modernize the GitHub pull request workflow for engineering teams. It layers on top of Git and GitHub, introducing stacked PRs, an AI-powered review engine with suggested fixes, and a merge queue — all without replacing your existing VCS.
Key technical capabilities:
- Stacked PRs workflow — create, manage, and rebase chains of dependent pull requests via CLI or VS Code extension, keeping diffs small and reviewable
- AI code review — automated review comments with actionable, inline fix suggestions surfaced directly in the PR
- Merge queue — serializes and validates merges to protect the main branch from broken builds
- CI optimization — reduces redundant CI runs across stacked and queued PRs
- PR inbox & team insights — aggregated view of open PRs with reviewer assignment and throughput metrics
- MCP integration — supports the Model Context Protocol for AI toolchain extensibility
Integrations: GitHub, Slack, VS Code, Git, MCP
