FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of FreeBSD was released in 1993. In 2005, FreeBSD was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed simply, permissively licensed BSD systems. FreeBSD has similarities with Linux, with two major differences in scope and licensing: FreeBSD maintains a complete system, i.e. the project delivers a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties for system software; and FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux.

OpenBSD is a free and open-source Unix-like operating system based on the Berkeley Software Distribution (BSD). Theo de Raadt created OpenBSD in 1995 by forking NetBSD. According to de Raadt, OpenBSD is a research operating system for developing security mitigations. The OpenBSD project maintains portable versions of many subsystems as packages for other operating systems. Because of the project's emphasis on code quality, many components are reused in other software projects. Android uses its C standard library, LLVM uses its regular expression library, and Windows 10 uses OpenSSH with LibreSSL. The name OpenBSD refers to the availability of the source code on the Internet. It also refers to the wide range of hardware platforms the system supports.

NetBSD is a free and open-source Unix-like operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems. The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures. Its source code is publicly available and permissively licensed.

Slackware is a Linux distribution created by Patrick Volkerding in 1993. Originally based on Softlanding Linux System, Slackware has been the basis for many other Linux distributions, most notably the first versions of SUSE Linux distributions, and is the oldest distribution that is still maintained. Slackware aims for design stability and simplicity and to be the most "Unix-like" Linux distribution. It makes as few modifications as possible to software packages from upstream and tries not to anticipate use cases or preclude user decisions. In contrast to most modern Linux distributions, Slackware provides no graphical installation procedure and no automatic dependency resolution of software packages. It uses plain text files and only a small set of shell scripts for configuration and administration. Without further modification it boots into a command-line interface environment.

Gentoo Linux is a Linux distribution built using the Portage package management system. Unlike a binary software distribution, the source code is compiled locally according to the user's preferences and is often optimized for the specific type of computer. Precompiled binaries are available for some larger packages or those with no available source code. Gentoo Linux was named after the fast-swimming gentoo penguin. The name was chosen to reflect the potential speed improvements of machine-specific optimization, which is a major feature of Gentoo. Gentoo package management is designed to be modular, portable, easy to maintain, and flexible. Gentoo describes itself as a meta-distribution because of its adaptability, in that the majority of users have configurations and sets of installed programs which are unique to the system and the applications they use.

GNOME is a free and open-source desktop environment for Unix-like operating systems. GNOME was originally an acronym for GNU Network Object Model Environment, but the acronym was dropped because it no longer reflected the vision of the GNOME project. GNOME is part of the GNU Project and developed by The GNOME Project which is composed of both volunteers and paid contributors, the largest corporate contributor being Red Hat. It is an international project that aims to develop software frameworks for the development of software, to program end-user applications based on these frameworks, and to coordinate efforts for internationalization and localization and accessibility of that software.

Arch Linux is a Linux distribution for computers with x86-64 processors. The Arch Linux repositories contain both libre, and nonfree software, and the default Arch Linux kernel contains nonfree proprietary blobs, hence the distribution is not endorsed by the GNU project. Arch Linux adheres to five principles: simplicity, modernity, pragmatism, user centrality and versatility. In general, the principles maintain minimal distribution-specific changes, minimal breakage with updates, pragmatic over ideological design choices, user-friendliness, and minimal bloat.

ALT Linux is a set of Russian RPM-based operating systems built on top of the Linux kernel and Sisyphus packages repository. ALT Linux has been developed collectively by ALT Linux Team developers community and ALT Linux Ltd. ALT Linux Team arose from the merger of IPLabs Linux Team and the Linux community of the Institute of Logic, Cognitive Science and Development of Personality. The latter cooperated with Mandrake Linux and SUSE teams to improve localization (specifically Cyrillic), producing a Linux-Mandrake Russian Edition (RE). Mandrake and Mandrake RE became different distributions and thus the decision was made to create a separate project. The name "ALT" was coined, which is a recursive acronym meaning "ALT Linux Team".

SteamOS is the primary operating system for the Steam Machine gaming platform by Valve. It is based on the Debian distribution of Linux. SteamOS is designed primarily for playing video games away from a PC (such as from the couch in one's living room) by providing a console-like experience using generic PC hardware that can connect directly to a television. It can run games natively that have been developed for Linux and purchased from the Steam store. Users are also able to stream games from their Windows, Mac or Linux computers to one running SteamOS, and it incorporates the same family sharing and restrictions as Steam on the desktop. Valve claims that it has "achieved significant performance increases in graphics processing" through SteamOS. The operating system is open source, allowing users to build on or adapt the source code, though the actual Steam client is closed.

Void Linux is an independent Linux distribution that uses the X Binary Package System (XBPS) package manager, which was designed and implemented from scratch, and the runit init system. Excluding binary kernel blobs, a base install is composed entirely of free software, but users can access an official non-free repository to install proprietary software.

MX Linux is a midweight Linux operating system based on Debian stable and using core antiX components, with additional software created or packaged by the MX community. It is developed as a cooperative venture between the antiX and former MEPIS communities, aiming to use the best tools and talents from each of these distributions. The community's stated goal is to "combine an elegant and efficient desktop with simple configuration, high stability, solid performance and medium-sized footprint". MX Linux uses the Xfce desktop environment, while KDE Plasma and other environments can be added or are available as "spin-off" ISO images.

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security. Kali Linux has over 600 preinstalled penetration-testing programs, including Armitage (a graphical cyber attack management tool), Nmap (a port scanner), Wireshark (a packet analyzer), John the Ripper password cracker, Aircrack-ng (a software suite for penetration-testing wireless LANs), Burp suite and OWASP ZAP web application security scanners. It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous information security testing Linux distribution based on Knoppix, originally it was designed with a focus on kernel auditing, from which it got its name Kernel Auditing LInux. The name is sometimes incorrectly assumed to come from Kali the Hindu goddess, or the Hindu demon. The third core developer, Raphaël Hertzog, joined them as a Debian expert.
