The desktop

Every app is a real window.

Snap them, Alt+Tab between them, spread them over several monitors. PosterFox, Steam and your other programs sit in the same taskbar.

PosterFox, Firefox that keeps to itself.

PosterChanOS's own browser: Mozilla's Firefox, built from source.

  • No telemetry, compiled out, and no Mozilla account.
  • uBlock Origin, Privacy Badger and PosterChan Passwords built in.
  • Every tab is its own container and presents a different real browser.
  • Tor tabs: .onion and the sites you choose open in Tor by themselves.

What's in it

Everything you use, signed in once.

Your desktop is your account

Apps, files and layout follow your Nostr key to any machine.

AI in every title bar

Ask it to do something and it fills, clicks and scrolls the window for you, on your own node. It asks before anything you can't take back.

Telegram built in

A full Telegram client; the session lives on your node.

Jellyfin media center

Movies and shows with subtitles and watch progress.

Virtual machine manager

Create, run and open consoles, managed over Nostr.

A full office suite

Edit Word, Excel and PowerPoint files.

Notes over Nostr

An encrypted notebook on every device. Imports from Joplin.

PosterFox browser

Firefox without telemetry. Every tab its own container and identity; Tor tabs. More

Steam in the box

Games launch from the start menu, and the pointer stays inside a fullscreen game.

Encrypted drive & folder sync

Your files on Blossom, synced between all your devices.

Quick Settings & Tor

Wi-Fi, Bluetooth, per-app volume, brightness, screenshots, and Tor with the exit country you pick.

Startup apps

Choose the programs that start when you log in.

Gentoo + Wayfire

Intel, AMD and NVIDIA, with LUKS full-disk encryption from the installer.

Install or upgrade

From a USB stick to your desktop.

The same image installs fresh or upgrades an existing install. An upgrade keeps everyone's home folder and files.

  1. Download

    Get the ISO above and check its SHA-256.

  2. Write it to a USB stick

    Any image writer works: balenaEtcher, Rufus (DD mode) or dd.

  3. Boot it

    Try the live desktop first, or go straight to the installer.

  4. Install or upgrade

    Pick “Install PosterChanOS”, or “Upgrade an installed PosterChanOS” to keep your files.
