Way too similar. People should come up with new ideas instead of cloning someone else's work.
I know there are other solutions like Gitlab, but from what people are saying here, it is harder to setup & maintain, so I do not feel that this particular product does not bring something new.
Maybe create an open source GitHub/Bitbucket UI that people can use in their projects?
And BitBucket was an attempt to steal GitHub's business primarily with Mercurial at the time, that Atlassian bought up, and since then GitHub has still been their #1 competitor, (not counting Sourceforge).
