Below is a list of small system distributions. These distributions are meant for devices with limited resources, like a wireless router for example. A free small system distribution is not self-hosting, but it must be developable and buildable on top of one of the free complete systems listed above, perhaps with the aid of free tools distributed alongside the small system distribution itself.

libreCMC is an embedded GNU/Linux distro for devices with very limited resources. While primarily targeting routers, it offers support for a wide range of devices and use cases. In 2015, LibreWRT merged with libreCMC.

ProteanOS is a new, small, and fast distribution for embedded devices. Its platform configuration feature allows binary packages to be configured at build-time and run-time for different hardware and use cases.
