Free Software Foundation

Stand up for your freedom to install free software

The FSF advocates for free software ideals as outlined in the Free Software Definition, works for adoption of free software and free media formats, and organizes activist campaigns against threats to user freedom like Windows 7, Apple's iPhone and OS X, DRM on music, ebooks and movies, and software patents. We promote completely free software distributions of GNU/Linux, and advocate that users of the GNU/Linux operating system switch to a distribution which respects their freedom. We drive development of the GNU operating system and maintain a list of high-priority free software projects to promote replacements for common proprietary applications. We build and update resources useful for the free software community like the Free Software Directory, and the free software jobs board. We also provide licenses for free software developers to share their code, including the GNU General Public License.
