Built on a stable foundation
Solid, secure,
built to last.
Built on KDE Plasma
A mature, open-source desktop. Stable, powerful and accountable to no one but its community.
Immutable Core
The system core is unchangeable. It stays clean, predictable, and stable. More stable than your first feature phone. You install software exactly as you always have.
Open Source
Every line of code is open for inspection. Security researchers, EU regulators, users, and hardware partners can verify for themselves that it is secure, private, and free of hidden telemetry.
Security Built In
State-of-the-art offline encryption and hardware-assisted security features, baked into the foundation from the start. Not bolted on as an afterthought.
Built for gamers
Your games.
All of them.
Steam and thousands of titles, ready to play. BlossomOS is a real gaming platform with the performance to back it up.
Built for work

EU compliance,
out of the box.

Fully auditable
Every line of code is open source and available for inspection. Your IT security team and any external auditor can verify exactly what runs on your machines.
No vendor lock-in
Open standards and open formats throughout. Your documents, data, and workflows belong to you, not to a subscription.
