You decide what an app can reach
When an app requests a file, camera, or network access, EuryOS is designed to make that request clear and let you choose.
A request you can understand
A familiar computer.
Every app in its own space.
EuryOS is being designed to give each app its own protected space, ask before it reaches your files, camera, or network, and contain failures so they are less likely to interrupt your work.

How EuryOS is designed
A clear path from permission to recovery.
The design starts with a simple idea: make app access visible, keep boundaries between parts, and plan for recovery when something goes wrong.
02
Apps stay in separate spaces
Each app is intended to run with a defined boundary, keeping its access to the rest of your system limited.
A boundary around each app
03
Failures stay contained
The system is being designed so a problem in one isolated component can be recovered without taking every other part with it.

Trusted core
A small foundation. Clear boundaries above it.
EuryOS is planned around a compact trusted core, with apps and system components separated by explicit boundaries. Implementation and verification details are still being defined.

Keep the trusted core small
EuryOS is designed around a small trusted core. The verification approach and results are still being defined.
Plan for recovery
Keeping components separate is intended to make it possible to recover one part without restarting the whole system. The recovery details are still being defined.
Separate system components
The architecture aims to give apps and system services clear boundaries, limiting how far a fault can spread.
Meet Calli
A computer that feels like a computer.
Calli is the desktop being built for EuryOS. These captures show its app design prototypes, with familiar windows and a shared visual language.

A note list and a quiet place to write.
Mail
Mailboxes, messages, and a reading pane.

FAQ
What we know so far.
EuryOS is in development. We will be clear where plans are still taking shape.
What is EuryOS?
EuryOS is an operating system in development, designed to make app permissions clearer and keep apps and system components in separate spaces.
Will it work on my computer and with my apps?
Supported hardware and app compatibility are still being defined. Join the list and tell us what you would like to use it on.
Has the security model been verified?
The verification approach and results have not been defined yet. We will share details as the project develops.
