Plug Computers are computers that fit in a small form-factor and are power-efficient. Most of the time, Plug Computers use a System-on-a-Chip (SoC) with an ARM processor, run a GNU/Linux system and are used as domestic servers.

Software freedom comparison

While some Plug Computers can be used with fully free software running on the main processor, not all of them are perfect. Hence, here is a comparison of different models of Plug Computers and their flaws regarding software freedom.
