Unfortunately, the source code of StationView is not available to the public, as this is proprietary software.
Possible alternatives (external to Raspberry Shake) can be using SWARM (USGS: Volcano Hazards Program), which is able to create a map from stations that are (for example) connected to particular networks, or contact gempa GmbH (https://www.gempa.de/) and ask for guidance/quotes for the advanced SeisComP software.
