Git is an open-source version-control system designed to handle very large projects that are distributed over multiple repositories.

Gerrit is a web-based code review system for projects that use git. Gerrit encourages more centralized use of Git by allowing all authorized users to submit changes, which are automatically merged if they pass code review. In addition, Gerrit makes reviewing easier by displaying changes side by side in-browser and enabling inline comments.

Jenkins is an open source continuous integration tool written in Java. The project was forked from Hudson after a dispute with Oracle. Jenkins provides continuous integration services for software development. It is a server-based system running in a servlet container such as Apache Tomcat. 

JIRA is a proprietary issue tracking product. It provides bug tracking, issue tracking, and project management functions. The Apache Software Foundation uses JIRA and Bugzilla. JIRA includes tools allowing migration from competitor Bugzilla.
