Distributions Linux

The KDE Plasma sibling to Bluefin within the Universal Blue project -- the same 'batteries included' immutable, Fedora-Kinoite-based image, with a Plasma desktop instead of GNOME.

A polished, developer- and gamer-oriented immutable desktop built on Fedora Silverblue's atomic base by the Universal Blue project, positioned as a 'batteries included' alternative to plain Silverblue.

An immutable, OSTree-based distribution built by a nonprofit-backed company for users with limited or no internet access, bundling a large offline app and content library directly into the OS image.

The KDE Plasma counterpart to Fedora Silverblue -- the same immutable, atomically-updated rpm-ostree base, with a Plasma desktop instead of GNOME.

Fedora's immutable desktop edition: the base operating system is a read-only image updated atomically, with everyday applications installed as sandboxed Flatpaks instead of traditional packages.

The GNOME project's own reference operating system image, built nightly from the very latest upstream GNOME code, primarily meant for testing and development rather than daily use.

A GNU project distribution built around the Guix package manager -- like NixOS, fully declarative and reproducible, but built in Guile Scheme and holding to a strict 100%-free-software policy.

A distribution built entirely around the Nix package manager's declarative model -- the whole system configuration, from installed packages to services and desktop, is described in one reproducible text file.

An immutable, Debian-based distribution offering an unmodified, stock GNOME desktop, with its own ABRoot system for atomic updates and dual-root A/B image swapping.

An immutable Arch-based distribution that lets a user run applications from Arch, Ubuntu, Fedora, and other distributions' package ecosystems simultaneously, each isolated in its own container.

openSUSE's polished, GNOME-based immutable desktop -- built on the MicroOS atomic-update core, using Flatpak for applications, and positioned as openSUSE's answer to Fedora Silverblue.

An immutable, self-updating, transactional version of openSUSE Tumbleweed's rolling package base, primarily aimed at container hosts and Kubernetes nodes, with desktop variants also available.
