there is also http://gitblit.com - only dependency is java.

looks like its quite feature rich - federation, verdict integration, plugins, active directory integration, etc and doesn't look like a github clone.

We are using gitblit. Installation and use is super easy. We have integrated it with LDAP for authentication and Jenkins for auto builds using hooks.

Gitblit surely must be the git world's hidden gem. It's less "Githubby" in features, but stacks up really well to commercial offerings like GitStack or Atlassian Stash.

I had the similar "omg, it just works" experience.
