Gerrit Code Review vs Perforce Helix Core

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.
