Bitbucket是一家为使用Mercurial和Git版本控制系统的项目提供网络托管服务的网站。Bitbucket既提供免费帐号，也提供商业付费方案。商业帐号可以使用无限数量的私有版本库（免费帐号至多支持5名用户）截至2010年9月 (2010-09)，而如果用户能邀请3位朋友注册Bitbucket，则至多可以为8名用户提供服务。私有版本库不会在个人页面上展示；如果用户只拥有私有版本库，网站则会显示还没有创建任何版本库，直到这名用户创建了公开版本库为止。Bitbucket使用Python下的Django Web应用框架编写。

Bitbucket is a web-based hosting service for projects that use either the Mercurial (since launch) or Git (since October 2011) revision control systems. Bitbucket offers both commercial plans and free accounts. It offers free accounts with an unlimited number of private repositories (which can have up to five users in the case of free accounts) as of September 2010, but by inviting three users to join Bitbucket, three more users can be added, for eight users in total. Bitbucket is written in Python using the Django web framework.
