Bitbucket: Bitbucket Data Center vs. GitHub Enterprise
As mentioned in our dedicated comparative page, there are several major feature differences between GitHub Enterprise and Bitbucket Server/Data Center. Most notably Bitbucket Server/Data Center provides additional workflow capabilities in the pull request experience, superior scalability (out of the box), and best-in-class integration with JIRA Software and Bamboo. This all comes at a fraction of the cost of GitHub Enterprise. For more information see our Bitbucket vs. GitHub Enterprise comparison.
