A simple OS
that just works.

What is smplOS?

smplOS is a minimal Arch Linux distro built around one idea: simplicity.

It started as an attempt to build a lighter version of Omarchy — same keybindings, same themes, but without the bloat. That contribution was rejected, so we forked and built our own distro. Along the way we rewrote most of the stack: a suite of lightweight GUI apps in Rust, a patched suckless terminal that renders inline images at a fraction of Kitty’s footprint, a cross-compositor architecture, and a theme system that touches every app on the desktop. What came out the other side isn’t Omarchy lite — it’s a different OS.

We built a modular edition system — productivity, creators, communication, development, AI — that stacks cleanly on top of a minimal base. Adding a new edition is just a package list and a post-install script, not a fork of the entire OS. The base idles under 800 MB of RAM, but you can stack every edition and still have a lighter system than most mainstream distros.

You can spin up sandboxed web apps on the fly — any website becomes an isolated app with its own window, its own profile, and no access to your main browser data. A 14-theme system recolors every app on the desktop with one command. Offline-first installation — no internet, under 2 minutes. Cross-compositor — same configs, themes, and keybindings across Hyprland and DWM.
