Linux, re-sliced
An operating system with everything you ordered and nothing you didn't.
Pizza OS is a Linux distribution built around one idea: your desktop should do exactly what you asked for. A browser, a game launcher, an office suite, and total control over how it all looks — no assistant watching over your shoulder, no monthly bill.

What comes in the box
Four apps, built for daily use — not for upsells.
Pizza OS keeps its core small on purpose. Everything else, you add through Toppings.
Crust
The default browser. Fast rendering, strict tracker blocking on by default, and tab groups that don't fight you for RAM.
Slice Arcade
One launcher for everything you play: 40+ titles built in, plus native support for your existing Steam, GOG, and itch.io libraries.
Pie Suite
Docs, sheets, and slides that open and save Word, Excel, and PowerPoint files. Fully offline, fully yours, no monthly seat fee.
Toppings
The customization layer: icon packs, dock position and behavior, tiling or floating windows, color themes down to the accent hex.
Slice Arcade menu
A game library that's already stocked.
A sample of what's pre-loaded. Everything runs the moment you open it — no launcher-within-a-launcher, no extra sign-in.
Plus 35 more titles in the base install, and native compatibility layers for Steam, GOG, and Lutris libraries.
Build your own slice
Four starting themes. One system that goes much further.
Toppings controls color, layout, icon set, and window behavior independently — these are just starting points.
Margherita
Light, warm, high contrast for daytime work.
Notte
Near-black base with a single tomato accent.
Basilico
Deep green base, built for long focus sessions.
Diavola
High-contrast red and charcoal, OLED-friendly.
Every layer is separate. Swap the color theme without touching your icon pack, keep a tiling window manager with a light palette, or move the dock to the side and drop it to two apps. Toppings ships as a settings panel, not a marketplace.
Take it home
One download. No account required.
Pizza OS installs from a single ISO, alongside or in place of your current system. Verify the checksum, write it to a USB drive, and boot.
