The Sigeon idea

A desktop that leaves room for the work.

Sigeon OS keeps the familiar parts close, removes the noise, and makes every system surface feel like it belongs to the same place.

Desktop, in your orbit

Familiar moves. A different atmosphere.

Search, organize, install, and keep your changes after every restart. The desktop stays quiet until you need it.

01 · Start

Begin with a search.

Find built-in tools, packages, and user apps from one dynamic Start surface.

  • Search applications as you type
  • Pin favorites without hiding running apps
  • Reach session and power controls in one place

02 · Files

Your files feel like yours.

Create, rename, move, open, and recursively delete files and folders. Changes persist after reboot.

  • Context actions for everyday file work
  • Desktop folders open directly in Files
  • User data lives on the persistent SIGEONDATA volume

Install what earns a place.

The repository includes command-line tools and Start-menu apps, all checksum verified and installed for the current user.

  • Cloud Notes, Pigeon Clock, Markdown Studio
  • Sig Studio, JSON Workbench, System Monitor
  • Installed apps never pin themselves automatically

Your flight plan

From ISO to a persistent desktop.

Public Release 2.0 targets x86-64 UEFI virtual machines and creates a system volume that keeps users, files, apps, pins, and settings.

01

Create a virtual machine

Use x86-64, enable UEFI, and add a virtual disk of at least 2 GiB.

02

Boot the release ISO

Attach the ISO, start the VM, and open the installer from the live desktop.

03

Choose the target disk

The installer creates the persistent system volume and verifies the installed data.

04

Detach and restart

Remove the ISO, then boot into your own persistent Sigeon OS desktop.

Persistent installation

Your desktop remembers.

Users, files, packages, pins, settings, and app data survive every reboot on the SIGEONDATA volume.
