What is it?

LordOS is a free GNU/Linux distribution built on Debian with its own desktop environment. The display server and Wayland compositor are written in C, the interface is driven by a React engine running on QuickJS, and the bundled apps are native to the system. It targets 64-bit PCs (amd64) and the Raspberry Pi 5 (arm64), and Linux applications such as Chromium, Firefox, and GTK and Qt apps can run alongside the native ones.

The system focuses on privacy and visibility. Installable LordOS apps run isolated and ask before accessing the camera, microphone, files, or network. A built-in firewall shows connections on a live map and lets users allow or block traffic per app, domain, address, or network, with support for public blocklists. Other bundled tools include a password vault, mail, calendar and contacts apps, a disk cleaner that only changes things after confirmation, and a remote desktop client for RDP and VNC.

The project is in beta. Releases ship as live and installable ISOs for PC and arm64 machines, and as an image for the Raspberry Pi 5. Users already on Debian 13 can install it on top of their current system with a single script.

Key features

  • 01Own display server and Wayland compositor written in C, without X11.
  • 02React-based interface engine running on QuickJS.

  • 06Runs on 64-bit PCs and the Raspberry Pi 5.

Use cases

  • Running a privacy-focused Linux desktop on an everyday PC.
  • Turning a Raspberry Pi 5 into a desktop or kiosk-style computer.
  • Trying out a Wayland desktop built from scratch on top of Debian.
  • Monitoring and restricting network access of individual applications.

Quick start

  1. 1

    Download the PC ISO or Raspberry Pi 5 image from GitHub Releases or lordos.org

  2. 2

    Build from source on the development machine (needs Node.js)

    npm install && npm run build
  3. 3

    Build the display server on Debian 13

    make -C server -j4 && make -C server test

Things to know

  • Status is beta, so breaking changes and rough edges are expected.
  • The Raspberry Pi 5 is the only supported board.
  • The generic arm64 ISO has only been tested on emulated QEMU.
  • Installing on top of an existing system requires Debian 13.
