We believe software should empower, not overwhelm.
Most operating systems ship with defaults that prioritize the loudest use case. SuMiOS starts from a different premise: you know how you work. We give you the environment, you make it yours. Fast boot, minimal surface area, zero unnecessary services running in the background.
SuMiOS is a complete operating system experience — a kernel-level foundation paired with a clean, modern UI layer. It runs on minimal hardware, boots in seconds, and stays out of your way.
SuMiOS boots in under 3 seconds on supported hardware. No splash screens, no welcome wizards — just your desktop when you need it.
No telemetry, no data collection, no phoning home. SuMiOS is designed with a firm stance: your machine, your data, your rules.
A streamlined UI that adapts to your workflow. Window management, app launching, and system controls — all one keystroke away.
Runs smoothly on hardware from the last 5 years. SuMiOS doesn't require 16GB of RAM to open a browser — it gets out of your way.
The OS ships with a plugin system and a clean API surface. Build your own tools, automate your setup, and make SuMiOS fit your stack.
Every layer is replaceable. Use the full desktop environment or strip it down to a headless server OS — it's your call.
The founding team spent months working on different machines — slow boot times, unnecessary services, and OSes that felt like they were fighting against the user. The idea for something cleaner started forming.
A stripped-down Linux base, a custom window manager, and a philosophy: every byte of code that ships must justify its existence. The first working prototype ran on 5-year-old hardware without a hiccup.
Shared with a small group of power users, developers, and designers. The response was consistent: "this is what I expected my OS to be." Feedback drove the architecture — privacy controls, plugin system, and clean UI patterns all came from real use.
Available to the public with a focus on transparency, speed, and the belief that an OS should serve its user — not the other way around.
SuMiOS is available now. Download it, try it, and see what a clean, fast, focused environment feels like.
