LibreCMC is a GNU/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.{{Cite web|last=|first=|date=|title=libreCMC FAQ|url=https://librecmc.org/faq.html|access-date=2020-07-03|website=librecmc.org}}

As of 2020, releases do not utilize codenames anymore. The acronym "CMC" in the libreCMC name stands for "Concurrent Machine Cluster".{{Cite web|date=2014-07-12|title=libreCMC: libreCMC|url=http://librecmc.org:80/librecmc/index|access-date=2021-01-26|archive-url=https://web.archive.org/web/20140712002641/http://librecmc.org:80/librecmc/index|archive-date=2014-07-12}}
