Gerrit Code Review vs Graphite

Gerrit Code Review is a free, self-hosted web system for collaborative review of Git repositories through patchset workflows. Teams can discuss changes with inline comments, manage patchsets, and configure approval processes. Fine-grained access controls determine who can access code. Gerrit lists integrations with Jenkins, GitHub Actions, Zuul, REST API, and webhooks for CI/CD and other automation. The project says global replication and active-active clustering can support thousands of concurrent developers, and presents the system for small teams through large organizations, including regulated industries. Gerrit is Apache 2.0 licensed. Its listed plan costs nothing, with no licensing fees and use at any scale without restrictions. Supported platforms are API, Linux, self-hosted, and web. Documentation and community provide support; the community supports the last three releases on a best-effort basis without a guaranteed response or resolution SLA. Plugin reliability is not guaranteed, and ongoing maintenance is not guaranteed for plugins without direct maintainers.

Graphite is an AI code review platform for teams working with GitHub repositories. Its CLI lets developers create, visualize, publish, update, and sync stacks of pull requests. A customizable PR inbox groups review requests and other PRs into sections, with search across synced repositories. Graphite Chat can summarize pull requests, answer code questions, suggest or apply edits, search codebase context, and help diagnose CI failures. The stack-aware merge queue automates merges and offers CI optimizations to skip redundant tests. Documented integrations include GitHub, Slack, and Linear, alongside a VS Code extension; documentation also describes a Mac menu bar app. GitHub is the only integrated Git provider, and new signups authenticate by installing its GitHub App. The free inbox tier allows three default repositories, compared with up to 30 for Team and Enterprise. Graphite says it does not offer self-hosting. Hobby is free; Starter costs $20 a month per user billed annually, and Team costs $40 a month per user billed annually. Enterprise pricing is custom, and a 30-day trial is listed.
