Deploy and Host Mullvad Browser (Cloud Browser) on Railway

This template runs a full desktop Mullvad Browser browser in the cloud, streamed to any device through the linuxserver.io Selkies web interface. Open your Railway domain, log in, and you're inside a real browser running on the server — bookmarks, extensions, downloads, and sessions persist between visits.

About Hosting Mullvad Browser

The service streams a GPU-less desktop Mullvad Browser over WebSockets with the linuxserver.io Selkies stack. Access is gated by HTTP basic auth (CUSTOM_USER / generated PASSWORD), and the browser profile persists on a volume at /config.

Common Use Cases

Fingerprint-resistant browsing sessions you can open from any device
Disposable browsing environment isolated from your real machine and network — open sketchy links without them touching your device
Persistent browser session with a stable egress IP: stay logged in to sites, resume long downloads, keep tabs running 24/7
Quick cross-check of geo-dependent or region-blocked content from a datacenter vantage point
Kiosk-style shared browser for a team (one URL, one login, same session state)

Dependencies for Mullvad Browser Hosting

Implementation Details

First use: open your Railway domain, log in with CUSTOM_USER and the generated PASSWORD (service Variables tab), and the desktop appears. On touch devices, use the sidebar for keyboard and gestures.

Notes and limits:

Keep the login strong: an open cloud browser is a proxy for whoever finds it. The password gate is the whole security model — don't remove it.
Rendering is CPU-based (no GPU on Railway). Fine for browsing and light video; not for WebGL-heavy work.
Mullvad Browser is memory-hungry: give the service 1–2 GB. Heavy tab hoarding needs more.
Mullvad Browser is the Tor Browser's anti-fingerprinting build without the Tor network, made with the Tor Project.
Want a mainstream engine? The same author publishes Chromium, Google Chrome, Firefox, Brave and Microsoft Edge templates too.
Traffic egresses from Railway's IP range — sites that block datacenter IPs (some streaming services) may object.
Abuse note: this is a browser, not an anonymizer. Use it within Railway's terms of service and the laws that apply to you.
