KDE Linux is a user-focused, general-purpose Linux distribution. It is built by KDE and it is meant to showcase the best implementation of everything KDE has to offer, using the most advanced technologies. The distribution's base packages come from Arch Linux, while everything else is either compiled by the kde-builder tool or included as Flatpak packages. KDE Linux does not come with any traditional package manager, but supports installing Flatpak, Snap or AppImage applications. As it has an immutable base, system updates involve replacing the operating system image with an entirely new one.

MocaccinoOS is an independently-developed Linux distribution that has its origins in source-based Gentoo Linux and Sabayon Linux. It uses a custom-built package manager called "Luet", which acts as a front-end for container-based software.

MocaccinoOS is offered in several variants, including live images with GNOME, KDE Plasma, MATE and Xfce desktops, as well as command-line-only "Minimal Desktop" edition.

NebiOS is an Ubuntu-based desktop Linux distribution with a custom Wayland compositor called NebiDE (based on Wayfire).

Gentoo Linux is a versatile and fast, completely free Linux distribution geared towards developers and network professionals. Unlike other distros, Gentoo Linux has an advanced package management system called Portage.

Senpai Respins is a set of (principally) MX Linux respins with Cinnamon, GNOME, LXDE, LXQT, MATE and Moksha desktops and window managers, user interfaces that the upstream project does not offer. It also provides a respin of Linux Mint Debian Edition (LMDE) with MATE, and MX Linux with the Parrot distribution installed on top of it. The MX Linux variants offer a choice between the systemd and SysV init systems. Other than integrating a new desktop into an existing distribution, Senpai brings very few other modifications, leaving the software composition and visual appearance of the upstream project intact.

TobbeOS is a minimalist, Arch-based Linux distribution featuring the Qtile tiling window manager. It provides a network installation image with a simple script that guides the user through the installation process; it downloads and installs the latest packages from Arch Linux repositories.

It is developed by Vipnix, a Brazilian IT solutions company specialising in customised infrastructure, cybersecurity, data protection and biotechnology.

Puppy Linux is yet another Linux distribution. What's different here is that Puppy is extraordinarily small, yet quite full-featured. Puppy boots into a ramdisk and, unlike live CD distributions that have to keep pulling stuff off the CD, it loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly. Puppy Linux has the ability to boot off a flash card or any USB memory device, CDROM, Zip disk or LS/120/240 Superdisk, floppy disks, internal hard drive. It can even use a multisession formatted CD-RW/DVD-RW to save everything back to the CD/DVD with no hard drive required at all.

AgarimOS is a desktop Linux distribution based on Void. It comes in several popular desktop flavours, including Cinnamon, GNOME, KDE Plasma, LXQt, MATE and Xfce, all with a limited set of applications in their default states. Like its parent, AgarimOS does not use the systemd service manager, relying instead on the runit init scheme. It employs the XBPS package management system, together with a graphical front-end called OctoXBPS. The distribution also includes various optimisations, custom themes and some interesting software selection, such as the WezTerm terminal emulator, the Neofetch system information utility, the hBlock ad blocker, and the aria2 download tool.

The distribution is free of systemd, using the runit init system instead.

Arch Linux is an independently developed, x86_64-optimised Linux distribution targeted at competent Linux users. It uses 'pacman', its home-grown package manager, to provide updates to the latest software applications with full dependency tracking. Operating on a rolling release system, Arch can be installed from a CD image or via an FTP server. The default install provides a solid base that enables users to create a custom installation. In addition, the Arch Build System (ABS) provides a way to easily build new packages, modify the configuration of stock packages, and share these packages with other users via the Arch Linux user repository.
