Intland's CodeBeamer offers much of the same capabilities in an integrated suite that Atlassian offers as individual applications. They are competing directly with their feature sets. CodeBeamer includes Subversion for version control, and tabs for build/release management, issue tracking, document management, identity management, communications and collaboration tools, and more. It is easy to use once you get used to it, albeit with a slightly clumsier user interface than Atlassian's products. It has an open API but is not open source-based, hence pricing is higher out of the box in exchange for very nominal systems administration costs over the lifetime of ownership.
