Actually I was going to add gitlab's name here too, but then I figured that'd go off topic. I think gitlab, because of its free CI, is actually even better than bitbucket.
Thanks Sbn, good to hear that. I think Bitbucket connect is very interesting and at GitLab we would like to have something similar. But since it is both used on-premises and as a SaaS this is more difficult. We're thinking about plugins but are afraid the fixed API's will make GitLab hard to refactor. So for now we welcome people contributing Project Services. The downside is that there is no business model for people contributing.
Stash, the the on premises version of Bitbucket that is also from Atlassian supports plugins and has a marketplace, so you can have plugins both on-premise and SaaS.
