github doesn&#x27;t really serve &quot;end users&quot; for the most part.  github is designed for libraries and pieces of open source that will be used by other developers.  So the &quot;end users&quot; github services are developers.<p>SourceForge is designed so that developers can serve their wares to end users.  As in, someone with a Windows PC that wants to download a media player.<p>This difference in use case is one reason that SourceForge&#x27;s top projects are all apps and github&#x27;s top projects are all libraries&#x2F;framerworks for use in development projects.
