Yeah, you could easily think you were looking at Github. I think it would be polite of them to change it a little bit more. Also, while it's natural for them to want to have a link to their Github account in the header of their site, as it is now (in combination with the extremely similar look) it almost makes them look like they are affiliated with Github.
Yea, Gitlab and Bitbucket are pretty significantly different in look. Although those two were commercial entities that probably had the foresight to think about these issues.
Gitbucket looks like it's independent devs just trying to create a clone in Scala. It would be pretty cool to have a github alternative in scala :-)
They also don't overtly describe themselves as Github clones. Slightly different goals: one tries to compete and aims to offer something superior, the other is intentionally a cheap knock-off (not intended to sound derogatory - there's a place for that).
