Links to Other Free Software Sites

To help promote knowledge of free software that isn't GNU software released under the auspices of the GNU Project, we have collected the following links to other web sites that contain free software, or are directly related to the issue of free software.

We do not have links to web sites of the well-known GNU/Linux system distributions, or to the well-known BSD system distributions, because all those sites explicitly describe, and facilitate access to, various nonfree programs. We would be glad to know of other free software web sites that we could link to here.

The FSF is not responsible for the contents of other web sites, or how up-to-date they are.

Free GNU/Linux distributions

We maintain information about fully-free GNU/Linux distributions.

Other free operating systems

We maintain information about fully-free system distributions that are not GNU/Linux.

Organizations that work for freedom in computer development and electronic communications

  • OpenCores

    The OpenCores project is a volunteer group interested in developing hardware, with a similar ethos to the free software movement: information on using the hardware must be available; the design of the hardware must be available; design software for hardware must be available. Note: The website describes the project by using the biased and confusing term “Intellectual Property,” which the GNU Project does not recommend.

  • Lumen

    Lumen, formerly Chilling Effects, is a collection point for cease and desist notices concerning online activity—we invite visitors to enter C&Ds they have received or sent. The website collects the C&Ds in a searchable database and hyperlinks them to explanations of the legal issues.
