Gerrit (/ˈɡɛrɪt/ GERR-it) is a free, web-based team code collaboration tool.

Software developers in a team can review each other's modifications on their source code using a Web browser and approve or reject those changes.

It integrates closely with Git, a distributed version control system.

Gerrit is a fork of Rietveld, a code review tool for Subversion.

[5] In versions 2.0–2.16 Gerrit used Google Web Toolkit[6] for its browser-based front-end.
