Gogs was on the HN front page yesterday[0]. The one cool thing that Gogs has for it is being written entirely in Golang. It does all of its work with Git with it's own implementation of Git[1]. This allows it to work and build on all platforms that Go is supported on without having to worry much about 3rd party tools.
