Nox OS Preview
Your computer,
without the noise.
Ubuntu 24.04 LTS and the COSMIC desktop, with our own shell and apps on top — one look, one language, nothing running behind your back.

The shell
Everything you need, one click away.
A thin panel, a dock and a control centre that answer the questions you actually have.
- Volume shows where the sound goes — “Headphones WH-1000XM5, 40%”, not just a bar.
- “Connected, but no internet” and hotel Wi-Fi login pages, said plainly.
- Four power modes with a line on what each one does, and an 80% charge limit.
- Media card with cover art and the player you choose.
- Do not disturb with exceptions, and a notification count on the lock screen.
Apps
Our own apps, one design.
The everyday tools are built for Nox: same window header, same buttons, light and dark themes, English and Russian.
Files
A fast file manager with tabs, drives, list and grid views.
Store
Catalogue apps and downloaded installers in one place, permissions shown first.
Terminal
Local shell, SSH and SFTP, saved hosts and split panes. No cloud.
Guard
Per-app limits for internet, camera and microphone, and per-app VPN or proxy.
Backups
Updates only when you click, a restore point before each one, and backups.
Share
Send screenshots and files through a private Tor link.
Viewer & Player
Photos and PDFs; video and music on the mpv engine.
Edit
A clean text editor with tabs.
Welcome
Language, Wi-Fi, theme, browser and apps on first start — skippable.
AntiPop
The quiet browser, preinstalled and updated with the system.
Theme “Nox”
Matching icons, login screen, boot menu and splash.
Installation
Install next to Windows. Calmly.
Try Nox from a USB stick without installing. When you do install, you see exactly what will change — before anything is written.
Next to Windows, or a whole disk
Put Nox on a free disk or partition and keep Windows as it is, or give Nox a whole drive. Disk encryption is offered during setup.
Secure Boot stays on Testing
Nox boots through the Microsoft-signed shim and Ubuntu’s signed kernel, and uses Canonical-signed NVIDIA drivers. No keys to enrol, nothing to switch off in the firmware — so Windows games that require Secure Boot keep working.
Updates when you say so
Nothing installs on its own. Press “Update”, and a restore point is made first. Nox and AntiPop come from our signed repository; the kernel, boot loader and drivers come only from Ubuntu.
Built on Ubuntu 24.04 LTS
Long-term support, the Ubuntu hardware kernel and the COSMIC desktop underneath. Software made for Ubuntu works here too.
Status
Where Nox is today.
Nox OS is in preview. We test every build in a virtual machine and on real hardware before publishing it. The first public installer image will appear on the download page with its size and checksum.
