The Free Software Foundation was founded by EMACS creator Richard Stallman to maintain the shared community that the early hackers had, and to counter the for-profit world with a set free software tools and operating system. Most of the Linux user space tools are based on FSF software, including awk, sed, cut, find, file, and innumerable others.

The Free Software Foundation created the GPL license, and are the creators of the GNU project and of Savannah.

They have a glossy and colourful webpage.
