Gerrit (/ˈɡɛrɪt/ GHERR-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. Both are namesakes of Dutch designer Gerrit Rietveld.[3][4]


Originally written in Python like Rietveld, it is now written in Java (Java EE Servlet) with SQL since version 2 and a custom-made Git-based database (NoteDb) since version 3.[5]

In versions 2.0–2.16 Gerrit used Google Web Toolkit[6] for its browser-based front-end. After being developed and used in parallel with GWT for versions 2.14–2.16, a new Polymer[7] web UI replaced the GWT UI in version 3.0.
