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

A full Fedora 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 dnf, browse the web, edit documents and keep everything between sessions, all behind a username and password.

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

The template runs the open source LinuxServer.io Webtop image (fedora-kde) as one Railway service. The 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, which is the desktop user's home folder, so your files, settings and installed browser profiles survive restarts and redeploys. The first boot takes a minute or two while KDE starts.

Common Use Cases

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

Dependencies for Fedora 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 dnf install -y gimp vlc

Give the service at least 2 GB of memory for a smooth KDE session; 4 GB is comfortable with a browser open. Image: lscr.io/linuxserver/webtop:fedora-kde (https://github.com/linuxserver/docker-webtop).
