TeamForge (formerly SourceForge Enterprise Edition or SFEE) is a proprietary collaborative application lifecycle management forge supporting version control and a software development management system.

Its predecessor, SourceForge, started as open source software, but a version of it (based on the v2.5 prototype code) was eventually relicensed under a proprietary software license as SourceForge Enterprise Edition, which was re-written in Java[2][3] and marketed for offshore outsourcing software development.

[4] The original codebase of SourceForge (code-named "Alexandria")[5] was forked by the GNU Project as GNU Savannah; then, Savannah was also modified at CERN and released as Savane.

Originally sold by VA Software, SourceForge Enterprise Edition was acquired by CollabNet on April 24, 2007.

[7] Since 2007, TeamForge has continued to undergo development, adding in a series of application lifecycle management tools.
