==== GNU Hurd ====
The original kernel of GNU Project is the [[GNU Hurd]] (together with the [[GNU Mach]] microkernel), which was the original focus of the [[Free Software Foundation]] (FSF).<ref name = "handbookonopensource" /><ref name = computerworld>Vaughan-Nichols, Steven J. "[https://www.computerworld.com/s/article/9131178/Opinion_The_top_10_operating_system_stinkers Opinion: The top 10 operating system stinkers]", ''[[Computerworld]]'', April 9, 2009: "... after more than 25 years in development, GNU remains incomplete: its kernel, Hurd, has never really made it out of the starting blocks. ... Almost no one has actually been able to use the OS; it's really more a set of ideas than an operating system."</ref><ref name= Hillesley>{{Citation | last = Hillesley | first = Richard | newspaper = The H | url = https://www.h-online.com/open/features/GNU-HURD-Altered-visions-and-lost-promise-1030942.html | edition = online | title = GNU HURD: Altered visions and lost promise | date = June 30, 2010 | page = [https://www.h-online.com/open/features/GNU-HURD-Altered-visions-and-lost-promise-1030942.html?page=3 3] | quote = Nearly twenty years later the HURD has still to reach maturity, and has never achieved production quality. ...

With the April 30, 2015 release of the Debian GNU/Hurd 2015 distro,<ref>{{Cite web|url=https://www.phoronix.com/scan.php?page=news_item&px=Debian-GNU-Hurd-2015|title=Debian GNU/Hurd 2015 Released – Phoronix|website=www.phoronix.com|access-date=2016-03-24}}</ref><ref>{{Cite web|url=https://lists.debian.org/debian-hurd/2015/04/msg00047.html|title=Debian GNU/Hurd 2015 released!|website=lists.debian.org|access-date=2016-03-24}}</ref> GNU now provides all required components to assemble an operating system that users can install and use on a computer.<ref name="status">{{Cite web|url=https://www.gnu.org/software/hurd/hurd/status.html|title=status|website=www.gnu.org|access-date=2016-03-24}}</ref><ref>{{Cite web|url=https://www.debian.org/ports/hurd/|title=Debian – Debian GNU/Hurd|website=www.debian.org|access-date=2016-03-24}}</ref><ref>{{Cite web|url=https://www.debian.org/ports/hurd/hurd-install|title=Debian – Debian GNU/Hurd – Configuration|website=www.debian.org|access-date=2016-03-24}}</ref>

However, the Hurd kernel is not yet considered production-ready but rather a base for further development and non-critical application usage.<ref>{{Citation | url=https://www.gnu.org/software/hurd/hurd/status.html | publisher = Free Software Foundation | title = Status | access-date = 2017-04-24 | date = 2015-05-03}}</ref><ref name="status" />

==== Linux-libre ====
In 2012, a fork of the [[Linux kernel]] became officially part of the GNU Project in the form of [[Linux-libre]], a variant of Linux with all proprietary components removed.<ref>{{cite web | url= https://directory.fsf.org/wiki/GNU_Linux-libre |title = GNU Linux-libre | date = 2012-12-17 | access-date = 2013-02-09}}</ref>
The GNU Project has endorsed Linux-libre distributions, such as [[Trisquel]], [[Parabola GNU/Linux-libre]], [[PureOS]] and [[GNU Guix System]].<ref>{{Citation | contribution-url = https://www.gnu.org/distros/free-distros.html | contribution = List of Free GNU/Linux Distributions | title = GNU Project | publisher = Free Software Foundation (FSF)}}.</ref>
