Atlassian, provider of the popular Bitbucket free code hosting service, and maker of collaboration tools for product development teams, announced the acquisition of SourceTree, a popular Mac client for Git and Mercurial distributed version control systems (DVCS) as well as Subversion source control. The company earlier announced that it added support for Git to Bitbucket, giving customers the option to use one of the most popular distributed version control systems available today. Bitbucket customers can now have unlimited private and public repositories for both Git and Mercurial in a single account.

SourceTree App, free for a limited time

SourceTree, a popular Mac client for managing repositories from Git and Mercurial DVCS systems, is available both on the Mac App Store since and via direct download from the SourceTree website. Following the acquisition, Atlassian is making SourceTree free for a limited time.

“SourceTree has won over the hearts and minds of its customer base by building a brilliantly engineered app,” said Mike Cannon-Brookes, CEO and co-founder of Atlassian. “SourceTree provides serious relief to the headache of managing multiple repositories, letting you manage and interface with multiple Git and Hg repositories visually through a client instead of the command line.”

”With its tremendous resources and strong track record of software craftsmanship, Atlassian was the perfect place for SourceTree to set down new roots,” said Steve Streeting, founder of SourceTree. “I’m looking forward to rolling up my sleeves and taking SourceTree to new heights.”

Bitbucket now rocks Git

Bitbucket capped a year of record growth – more than tripling the number of accounts and adding over 350 improvements, bug fixes and new features – and this week has announced support for Git alongside the already supported Mercurial DVCS. By adding Git support, Bitbucket now offers customers the ability to use both Git and Mercurial repositories within a single code hosting and collaboration service, without limiting the number of private or public repositories users can create and manage within a single account.

“Distributed version control is meant to be exactly that – distributed – but most services either limit the number of repositories their users can manage, or charge by repository which discourages forking and code collaboration,” said Mike Cannon-Brookes, CEO and Co-founder of Atlassian. “Today we’re offering unlimited private and Git repos free for teams of five developers.”
