Deploy and Host Debian Linux Desktop (KDE Plasma) in your browser on Railway

A full Debian Linux desktop with KDE Plasma that runs in the cloud and opens in any modern browser, on a laptop, tablet or phone. Install apps with apt, browse the web, edit documents and keep everything between sessions, all behind a username and password.

About Hosting Debian Linux Desktop (KDE Plasma) in your browser

The template runs the open source LinuxServer.io image webtop:debian-kde as one Railway service. The Debian KDE Plasma desktop is streamed to your browser over Railway's HTTPS domain on port 3000, and HTTP basic auth protects it with CUSTOM_USER and a generated PASSWORD that you copy from the service Variables. A volume is mounted at /config, the desktop user's home folder, so your files, settings and browser profiles survive restarts and redeploys. The first boot takes a minute or two.

Common Use Cases

A private Linux desktop you can reach from any device, including Chromebooks and iPads
A stable Debian workspace for long downloads, scripts or tools that keep running when your laptop is closed
Trying KDE Plasma without installing anything on your own computer

Dependencies for Debian Linux Desktop (KDE Plasma) in your browser Hosting

No other services: one container plus a volume
A modern browser; Chrome, Edge, Firefox and Safari all work

Implementation Details

Open the Railway domain, sign in with CUSTOM_USER and PASSWORD, and the desktop loads. The desktop user has passwordless sudo, so you can install software:

sudo apt update && sudo apt install -y gimp vlc

Give the service at least 2 GB of memory for a smooth session. Image: lscr.io/webtop:debian-kde (https://github.com/linuxserver/docker-webtop).
