VitruvianOS

Introducing the Janus Privileged Launcher

Tue, 02 Jun 2026 00:00:00 +0000

You know how on a normal Linux desktop you need a display manager to log in, and then a bunch of services start in the background, Vitruvian works differently but not too much. It uses a privileged launcher called janus that does all of that and more.

Its job is to bring up the entire Vitruvian desktop and keep it running until shutdown. It replaces a display manager, it replaces a traditional init style service launcher, and it does a bunch of low level hardware coordination that neither of those normally handles.

VitruvianOS 0.4.0

Tue, 02 Jun 2026 00:00:00 +0000

A broad foundation release: better hardware support, a saner desktop session, and a more reliable build pipeline.

What’s new from 0.3.2

Desktop session manager (janus). Vitruvian now starts, manages, and shuts down its servers through a proper session manager instead of ad-hoc scripts. Logins and reboots are cleaner and more predictable.

Display and input

The graphics backend works on more GPUs and handles multi-seat hardware transitions cleanly. Keyboard input now uses the native Linux keymap system, so non-US layouts and special keys start to behave the way you’d expect.

VitruvianOS 0.3.2

Sat, 04 Apr 2026 00:00:00 +0000

We are pleased to announce the release of Vitruvian OS 0.3.2. This is a bit of an anticipated release in preparation of big changes for the next.

We would like to thank everyone again for the encouraging amount of support!

What you will find in the new ISO:

Stability fixes
Pulse, DiskProbe, ActivityMonitor and other apps are beginning to work.
Devices enumeration (fs features start appearing)
Lots of minor fixes

You can download the iso at the following link:

VitruvianOS 0.3.1

As promised we are pleased to announce the release of Vitruvian OS 0.3.1.

We would like to thank everyone for the encouraging amount of support for the first public release of Vitruvian.

What you will find in the new ISO:

Resolved most problems with icons.
Lots of new apps and preferences
Double buffering in app_server
Fixed BIOS Machines Boot
Improved general stability
Tracker fixes
Kernel fixes

VitruvianOS 0.3.0

Mon, 23 Mar 2026 00:00:00 +0000

VitruvianOS — is an operating system built on Linux that is inspired by the BeOS. After years of quiet development, we’re thrilled to announce the first public release of VitruvianOS 0.3.0.

This is a milestone moment—not just for us.

Why Now?

We started the first experiments in 2019, but the first announcement was more of a quiet signal to the few people who might care.

Porting a BeOS-compatible runtime on top of Linux isn’t like repackaging existing tools. We built the entire infrastructure from scratch—a sophisticated layer that allows the Tracker, Deskbar, and the rest of the Vitruvian experience to run as fully native Linux applications.

Building a Haiku Runtime on Linux: The Road So Far

Tue, 10 Feb 2026 00:00:00 +0000

One of the core challenges in building V\OS is bridging two worlds: the Linux kernel’s POSIX model and the BeOS/Haiku API’s distinct approach to system services (messaging, node monitoring, virtual filesystems, and more). This post gives a brief look at how we are approaching it.

The Kernel Bridge

Rather than running a BeOS kernel, Vitruvian implements the missing pieces as Linux kernel modules. The nexus module brings BeOS-style node monitoring to Linux’s fsnotify subsystem, translating filesystem events into the B_NODE_MONITOR messages that BeOS/Haiku applications expect. This allows Tracker, the file manager, to watch directories and respond to changes in real time, exactly as it would on native Haiku.

Vitruvian: an operating system built on Linux that brings the elegance and simplicity of BeOS to modern hardware.

Vitruvian is in active development. Daily builds will be soon available for early adopters who want to follow progress. The system boots on modern x86-64 hardware, runs a Linux kernel, and includes a working BeOS/Haiku API compatibility layer.

About Vitruvian

Mon, 01 Jan 0001 00:00:00 +0000

What is VitruvianOS?

Vitruvian, also known as V\OS, is the human-centric Operating System. Built on Linux and inspired by BeOS, it brings the elegance and simplicity of a classic operating system to modern hardware without sacrificing the power and hardware support that Linux provides.

Custom-built kernel modules deliver a responsive, low-latency desktop experience. The BeOS/Haiku API is supported on Linux with minimal to no changes required to application source code.

FAQ

Mon, 01 Jan 0001 00:00:00 +0000

What is VitruvianOS?

Vitruvian is an operating system based on Linux, inspired by the BeOS. It brings the BeOS/Haiku API and desktop philosophy to modern hardware, running on a Linux kernel with custom kernel modules.

Is it based on Haiku?

Partially. Vitruvian uses the Linux kernel and implements the BeOS/Haiku API compatibility layer on top of it. It is inspired by both BeOS and Haiku but is an independent project built from the ground up where we picked the best available open source components.
