| LibreCMC | Active | Linux-libre | MIPS | | GPLv2 | Free | Linux-libre distribution for computers with minimal resources, such as the Ben NanoNote, ath9k-based Wi-Fi routers, and other hardware with emphasis on free software. Based on OpenWrt, the project's goal is to aim for compliance with the GNU Free System Distribution Guidelines (GNU FSDG) and ensure that the project continues to meet these requirements set forth by the Free Software Foundation (FSF). LibreCMC does not support ac (Wi-Fi 5) or ax (Wi-Fi 6) due to a lack of free chipsets. |
| m0n0wall | Discontinued | FreeBSD derivative | x86 | | ? | Free | Development ended 2015-02-15. Small web-administrative router/firewall/VPN (IPsec/PPTP only; no OpenVPN) distribution. m0n0wall was forked to smallwall.org shortly after Manuel Kasper announced end of development for m0n0wall. |
