Following are the 
GNU/Linux distributions I know of which have a firm policy commitment to only include and only propose free software.  They reject non-free applications, non-free programming platforms, non-free drivers, or non-free firmware “blobs”.  If by mistake they do include any, they remove it.  To learn more about what makes for a free GNU/Linux distribution, see 
Guidelines for Free System Distributions.
Some distributions are making efforts to move toward a completely free system.  We thank them for their ongoing work to achieve that goal, and hope to list them here some day.
Information about 
individual GNU packages (most of which are included in the free distros here) is available separately.
All of the distributions that follow are installable to a computer's hard drive and most can be run live.  They are listed in alphabetical order.
