Guix System (formerly Guix System Distribution, or GuixSD) is a Linux-based, stateless operating system that is built around the GNU Guix package manager. The operating system provides advanced package management features such as transactional upgrades and roll-backs, reproducible build environments, unprivileged package management, and per-user profiles. It uses low-level mechanisms from the Nix package manager, but packages are defined as native Guile modules, using extensions to the Scheme language.

GXDE OS is a desktop-oriented Linux distribution that combines Debian with Deepin Desktop Environment (DDE), developed by the deepin project. It is based on Debian's "Testing" branch. It ships with up-to-date Linux kernel, base system and applications, and it includes a "Spark Store", a software application marketplace with support for Android applications. The distribution is available for the aarch64 and x86_64 processor architectures.

HackerOS is a live Linux distribution based on Debian's "Testing" branch and designed for regular users, gamers and cybersecurity enthusiasts. Some of its features include an optimised XanMod Linux kernel for faster boot times and reduced resource usage, out-of-the-box support for NVIDIA graphics cards, and a collection of cybersecurity tools, such as enhanced firewalls and intrusion detection software. The distribution uses the KDE Plasma desktop.

Haiku is an open-source operating system, currently in development, that specifically targets personal computing. Inspired by the Be Operating System (BeOS), Haiku aims to become a fast, efficient, simple to use, easy to learn and yet very powerful system for computer users of all levels. The key highlights that distinguish Haiku from other operating systems include: specific focus on personal computing, custom kernel designed for responsiveness, fully threaded design for great efficiency with multi-processor/core CPUs, rich object-oriented API for faster development, database-like file system (BFS) with support for indexed metadata, and unified, cohesive interface.

Helwan Linux is an Arch-based Linux distribution designed for home, education and development use. Its "Home" flavour comes with the GNOME desktop, the "Edu" variant ships with Xfce and the "Dev" edition features the Cinnamon desktop together with a range of compilers and interpreters, including PHP and Rust. The project also produces a comprehensive "Distro Building" manual with a guide to the Archiso tool (for building custom Arch-based ISO images) and the Calamares system installer.

Huayra GNU/Linux is a Debian-based Linux distribution developed in Argentina by Educ.ar, a state-owned company, under the "Conectar Igualdad" government programme. It contains open educational resources and applications that are useful in the school setting, for which it was designed. The distribution uses the MATE desktop environment. Apart from many popular open-source applications, Huayra GNU/Linux also ships a number of custom-built tools, including Huayra Share (for sharing files between two computers running this system, without the need for Internet connection), Huayra Motion (for creating stop motion graphics), Huayra TDA Player (for watching free-to-air digital television), and Pilas Engine (a video game development environment).
