The name

What EUZOS stands for.

Three parts, one idea: made in Europe, built from zero, and a complete operating system.

The story

Four layers. One maker. Built from the core up.

EUZOS is not a shell on top of someone else's system. Every layer, from the kernel to the phone you sign in with, is developed as one platform.

02Desktop

01 · Kernel

It starts with our own kernel.

Written in Rust, a memory-safe language, so whole classes of errors cannot occur. Drivers, network, TLS, desktop and apps are built on it as one platform. Hardware drivers are made clean-room from written specifications: Linux driver code is never copied.

Rust: memory-safe, from the first line of code
2: processor architectures: x86-64 and ARM64
20 s: a new kernel that crashes or hangs restarts itself into the last good one

02 · EUZOS Desktop

A desktop that speaks your language.

For PCs, laptops and tablets: its own apps for browsing, email, files, calendar and the terminal, signing in with your phone, and every text in 34 European languages.

34: languages: the 24 official EU languages and ten more
3: ways to sign in: your phone, a password or a Microsoft work account

03 · EUZOS Server

Servers you manage from your desk.

The same kernel as a server edition: web server, file server, DNS, backup and databases as roles and packages, a firewall that is closed by default, and everything managed in Server Admin on an EUZOS PC.

1: codebase, two editions: what a server does not need is not in its kernel
TLS 1.3: with post-quantum key exchange X25519MLKEM768

04 · EUZOS Profile

Your phone is the key.

Scan the code on the login screen, confirm with Face ID or your fingerprint, and your profile follows you to any EUZOS PC. Work accounts sign in with Microsoft Entra ID; organisations manage users and the app catalogue on the profile server.

30 s: a fresh sign-in code on the screen every half minute
Offline: sign in without internet after a first online login

Updates with a safety net

Every new kernel gets a trial run.

A new kernel starts once as a trial. Only when it works is it committed; otherwise the PC simply starts the previous kernel again. Translations, icons and many drivers update without a restart at all.

3: update layers: data, drivers and core

Works: committed
Fails: back to the last good kernel

Built in Europe

Digital autonomy, by design.

EUZOS is developed in Europe, for people and organisations that want to know what their software depends on.

Privacy
No tracking and no analytics on this website, and a privacy section in the settings of EUZOS itself.
Autonomy
An own kernel and own core code: the foundation does not depend on a supplier outside Europe.
Own code
Outside software only by exception: every exception is recorded, approved and re-assessed every 6 months.
Every European language
The 24 official EU languages plus Turkish, Ukrainian, Norwegian, Icelandic and more: 34 in all.
