SourceForge is a web-based source code repository. It acts as a centralized location for software developers to control and manage free and open source software development. It was the first to offer this service for free to open source projects.[2][discuss] The website runs a version of SourceForge Enterprise Edition, forked from the last open-source version available. As of May 2013, the SourceForge repository hosts more than 300,000 projects and has more than 3 million registered users,[3] although not all are active. The domain sourceforge.net attracted at least 33 million visitors by August 2009 according to a Compete.com survey.[4]
SourceForge offers free access to hosting and tools for developers of free / open source software, competing with other providers such as GitHub, RubyForge, Tigris.org, BountySource, Launchpad, BerliOS, JavaForge, GNU Savannah, and Gitorious.
