Philosophy and Foundations

At its heart, SlyOS is more than just another Linux distribution — it is a deliberate vision of what an Arch-based system should be: straightforward, lightweight, respectful of user freedom, and unburdened by unnecessary complexity. Born from a desire to make a properly configured Arch-like experience accessible to a wider audience, SlyOS removes the often-intimidating setup process that greets new users on vanilla Arch, while staying true to the principles that make Arch so beloved. It is built on Artix Linux and follows the famous KISS principle — Keep It Simple, Stupid — meaning every component serves a clear purpose, nothing is included just for show, and the system remains lean and responsive.

One of SlyOS’s most defining choices is its commitment to operating entirely without systemd. Instead, it uses OpenRC, a modular, lightweight init system that gives the system a cleaner architecture and a smaller footprint. This is not merely a technical preference; it is a philosophical stance in favour of simplicity and modular design. SlyOS also deliberately avoids Qt libraries wherever possible, favouring GTK and related technologies to maintain consistency, reduce dependencies, and keep the system unified and lightweight.

Privacy is woven into SlyOS’s DNA. The project believes that true freedom on the internet includes being able to access information and express yourself without being tracked, profiled, or asked for personal data such as an email address. SlyOS ships with privacy-conscious applications by default and encourages tools that isolate applications from one another — such as Flatpak — so that software behaves predictably and stays within the boundaries you set.

SlyOS is built entirely on quality free and open-source software, with a deliberate preference for lesser-known but genuinely excellent applications. This is partly to showcase great tools that deserve wider recognition, and partly to avoid the bloat and corporate influence that can creep into more mainstream alternatives. Every piece of software included is chosen because it does its job well, respects your system, and aligns with the project’s values.

Under the Hood: Technology and Installation

SlyOS 0.2, known by the codename “Invativ”, was released in late August 2026 and represents the project’s current flagship. It is built for the x86_64 architecture and ships in two distinct editions — Niri Complete and Niri Minimal — so you can choose exactly what you start with. Both editions use the Niri compositor, a modern scrollable-tiling Wayland window manager that arranges windows in columns and lets you navigate smoothly between them. For a login manager, SlyOS uses ReGreet, based on Greetd — a lightweight alternative to heavier display managers — ensuring the system stays fast all the way from boot to desktop.

Underneath the graphical layer runs the Linux kernel from CachyOS, built on a long-term support branch. This offers a careful balance between cutting-edge performance and reliable stability, with updates and security patches maintained over an extended period. The system is built on Artix Linux, which itself is an Arch-compatible distribution designed explicitly without systemd. This means SlyOS enjoys the rolling-release model Arch is famous for — always up to date, without version upgrades or system reinstalls — but with a carefully curated foundation that aligns perfectly with SlyOS’s lightweight goals.

Installation is handled by Calamares, a widely respected system installer that SlyOS keeps up to date. The process is straightforward: you select your language, keyboard layout, region, and timezone — with full support for multiple languages including English, French, Spanish, German, Italian, Portuguese, Russian, Polish, Czech and more — then choose your partitioning scheme. At present, the installer uses the ext4 filesystem alongside a FAT32 EFI partition and a swap partition. Support for Btrfs is not currently available in the installer due to known bootloader compatibility issues, a limitation the project acknowledges and is actively working to resolve.

Once installed, the system boots using GRUB, and Plymouth provides a clean boot screen. The full install creates a standard layout: around 1 GiB for the EFI partition, roughly 17.5 GiB for swap, and the remainder for the root filesystem, all on a modern GPT partition table. In a default virtual machine test, the system boots quickly, uses around 5% of available memory at idle, and feels responsive — exactly what you would hope for from a lightweight distribution.

Package management follows Arch conventions: you have Pacman at the command line and Pamac as a graphical alternative. Flatpak is also built in from the start, giving you immediate access to thousands of applications in a secure, sandboxed format. All told, a default installation includes around 840 packages — a modest base that leaves you in control of what else you add.

Daily Use, Apps, and Workflow

The first time you log in to SlyOS, you are greeted by a friendly guided tour that walks you through the essentials. You learn the keyboard shortcuts that make Niri so efficient: hold the Windows key to open a terminal, launch your web browser, open the application launcher, close windows, and move smoothly between windows and workspaces. These shortcuts are simple, consistent, and easy to memorise — and they make the system feel fast and capable right from day one.

The tour continues with system updates, Flatpak tools, gaming recommendations, preinstalled applications, and suggested software. It concludes with Thymbr — SlyOS’s own control centre — where you can adjust appearance, manage users, configure networks, and fine-tune your desktop from one unified place. It is a thoughtful introduction that bridges the gap between a tiling window manager and a friendly, usable desktop.

Flatpak is central to the SlyOS experience. Three tools are provided to make it easy: Bazaar, an app store that lets you browse and install applications graphically; Warehouse, a powerful Flatpak manager for managing remotes and updates; and Flatseal, an indispensable tool that lets you control exactly what permissions each Flatpak application holds — access to your files, your devices, your network, and more. Together they give you the breadth of Flatpak’s ecosystem without the complexity of command-line management.

For everyday work, SlyOS ships with a carefully chosen selection of applications. LibreWolf offers a privacy-hardened web browser. GIMP and Inkscape provide powerful image editing and vector graphics. Tenacity offers multi-track audio editing, Gapless plays music beautifully and without ads, and GPU Screen Recorder captures your screen efficiently using hardware acceleration. There is also a system monitor, a menu editor, and a suite of smaller utilities — all chosen because they work well, look good, and respect your resources.

If you enjoy gaming, SlyOS recommends installing Steam and Bottles through Flatpak. Bottles in particular makes running Windows games straightforward, while Prism Launcher, Heroic Games Launcher, and ProtonPlus are suggested through the recommended software list. You will also find suggestions for productivity, creativity, and utility applications — all available through Bazaar or Pamac — so you can expand your system without losing sight of what matters.

In use, SlyOS feels polished, coherent, and remarkably fast. It avoids the heavy hand-holding and resource consumption of larger desktops, yet it provides all the conveniences you actually need. Updates are reliable, the filesystem stays clean, and because it follows a rolling-release model, you never have to wait months for new features. It is an Arch-based system that behaves exactly as Arch users would hope — but one that is ready to use, configured well, and welcoming to newcomers.

Conclusion

SlyOS is a thoughtful, principled distribution that succeeds in making Arch Linux accessible, lightweight, and privacy-respecting. It removes the barrier of initial setup without stripping away Arch’s core strengths, and it builds a coherent experience around OpenRC, the Niri compositor, and Flatpak. It is not perfect — notably the absence of Btrfs support in the installer is a limitation — but it is honest about its known issues and actively working to improve. If you value simplicity, performance, privacy, and a system that stays out of your way, SlyOS deserves your attention. It is Arch as it should be: free, capable, and refreshingly straightforward.
