Gerrit is the website where all Wikimedia repositories are stored and proposed code changes to those repositories are reviewed. All code changes that are submitted to Gerrit are reviewed on the Gerrit website before being submitted to ensure they meet acceptable code styling, implementation, and security standards.

All Gerrit users can review contributions. Maintainers have the special rights to approve or reject contributions.
