Runs in a browser tab
An operating system
that is actually yours.
Windows, a real filesystem, sandboxed apps and cryptographic sessions — all inside your browser. Nothing is uploaded, because there is nowhere to upload it to.
Welcome back — your session lives on this device.
Every session starts the same way
Locked until you say otherwise.
AES-256-GCM at rest
Your password derives the key. It is never sent anywhere.
In memory only. Wiped the moment the tab closes.
Origin Private FileSystem
A real filesystem. On your machine.
Folders, trash, tags, quick look. Every byte lives in your browser's own private storage — not a server's disk, not a bucket somewhere. Duxner has no account to sign into and nothing to sync.
Every app, chrooted
It only gets what it asks for.
Apps declare what they need and get nothing more. Paths are chrooted, runaway loops are killed after five seconds, and an app that crashes takes down only itself — never the system around it.
"Weather" wants access to
Network — weather.example.com only
Where your files actually are
Encrypted. On this device. Nowhere else.
Everything an app produces — a screenshot, an export, a saved file — is written inside the OS. Nothing leaves unless you export or share it, and then it goes exactly where you point it.
Which also means the usual warning applies: clearing your browser's site data clears Duxner. Keep a backup of anything you would miss.
