The Signal Desktop app running in the cloud and streamed to any browser. Link it to your phone once and reach your Signal chats from any computer, with the linked session kept on a volume.

About Hosting Signal Desktop in your browser

The template runs the open source LinuxServer.io image signal:latest as one Railway service. Signal Desktop runs inside a minimal desktop and is streamed to your browser over Railway's HTTPS domain on port 3000. 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, so your linked session and settings survive restarts and redeploys. The first boot takes a minute or two.

Common Use Cases

Reading and answering Signal messages from any computer
Using Signal on machines where you cannot install apps
An always-on linked Signal session
