Con Private repositories are free for only 5 users
Private repositories are free for teams with 5 members or less. If a team is larger, then BitBucket charges for each additional team member.
Con Not as stable as github
Users have experienced several half a day downtimes, almost every month. True, github is down once in a while, but when GitHub is down complaints breaks loose on Twitter, TechCrunch, and other major media outlets. For the past 5 years github has been down only three times, and two of these times they were attacked by major adversaries.
Con Requires registration of a "universal atlassian account"
Not a big con for some, but annoying to others.
Con Difficult to configure
Compared to a solution like Bitbucket Server (granted Phabricator offers more options), it is difficult to configure. Settings are scattered everywhere and you must drill down through several screens to find some of them. Documentation is very complete but also not always in parity with the application itself.
