Wasabe OS

One Linux desktop. Two ways to sit in front of it.

We’re building Wasabe OS: a Fedora-based operating system with its own desktop, real applications and an assistant designed to work across the tools you have approved. Use it on supported hardware, or access the same OS through your browser with Wasabe Runtime on your own computer.

Two experiences

The same OS, on a device or through Runtime.

Native device installation

Where apps execute Applications run directly on supported hardware running Wasabe OS.

What you install The Wasabe OS image, through its installer — once that installer is qualified.

Wasabe Runtime on an existing computer

Where apps execute Applications run inside a persistent local Linux VM.

What you install A native Wasabe Runtime for the host platform — once a supported build is available.

Native installation remains part of the product direction. Our first acceptance target is the local Apple Silicon VM, followed immediately by browser access through the Runtime. Broader host and hardware support follows qualification. There is no installer or Runtime download on this site yet.

Wasabe Runtime

Host software for the VM. Not the engine inside the OS.

Wasabe Runtime is the installed host software that runs the persistent Linux VM on an existing Windows, macOS or Linux computer. Wasabe Web Runtime is the shared web engine inside the OS that executes Wasabe apps. They are different components that have historically shared a name.

Install once

Wasabe Runtime provisions the OS image, manages the VM and persistent storage, and pairs with the browser.

The browser is the display

The browser displays and controls the actual Linux desktop through an authenticated local connection. It is not a separate web desktop product.

Closing a tab is not shutdown

The Runtime’s lifecycle policy decides whether the VM continues, idles or suspends. Applications and files live on persistent storage.

Local first

Same-machine desktop video stays local. Optional cloud services can later cover identity, AI, updates, distribution, sync and backup. Remote access is a separate, permissioned future capability.

Architecture

A Linux foundation. A Wasabe desktop.

The base is Fedora Linux, with normal Linux drivers, system services and package infrastructure. Wasabe supplies its own desktop and window manager. GNOME is not the desktop underneath the Wasabe interface. React renders the shell; Rust owns native window management, placement, focus, input, workspaces, compositing and permission-controlled system operations.

Fedora foundation

Kernel, drivers, package ecosystem and Linux services.

Wasabe Rust compositor

Native Wayland/XWayland windows, display, input and workspaces.

Wasabe shell

The existing React desktop and system presentation on OS-owned surfaces.

Wasabe Web Runtime

The shared, system-managed web engine inside the OS — not the host Runtime you install on macOS, Windows or Linux.

Rust System Bridge

Typed, identity-bound, permission-controlled native operations.

AppKit

Application packaging, lifecycle, integration and developer contracts.

Wasabe agent

A shared assistant with scoped tools and approved app actions.

Native liquid glass is in development as a shared OS material for window chrome and the dock. We are not presenting a mockup of it as a shipped or benchmarked effect.

Applications

Wasabe apps and ordinary Linux apps, on the same desktop.

Existing Wasabe applications are being converted into real native windows while preserving their content, features and logic. A catalog tile is not a release-ready application. Normal Linux applications coexist through the same desktop — Fedora packages, RPM/DNF and Flatpak, with Wayland and XWayland. We do not claim every Linux app works.

Availability

What is true today.

In development

Fedora-based OS with the retained React desktop and Rust window authority. Working development VM; not a completed OS release.

Next milestone

Browser access through a distributable host Runtime, after local-VM acceptance. There is no downloadable completed Runtime today.

Still to qualify

Native hardware installer, broader host support, and a published compatibility matrix. ARM64 and x86-64 need their own builds.
