Gitblit is an open-source, pure Java stack for managing, viewing, and serving Git repositories. It's designed primarily as a tool for small workgroups who want to host centralized repositories. Gitblit WAR is what you should download if you already have a servlet container available that you wish to use. Jetty 6/7/8 and Tomcat 6/7 are known to work. Generally, any Servlet 2.5 or Servlet 3.0 container should work.
