You could attach an rtl-sdr to a raspberry pi and locally host a websdr server (https://github.com/jketterl/openwebrx https://github.com/jketterl/openwebrx is a good open source one). The rtl-sdr doesn't have a high enough sample rate to cover about half of the commercial fm broadcast spectrum at a time where you can see quickly switch between stations in that portion e.g. 89-94 Mhz. Going to the other half just requires having two different modes and switching between them in the websdr interface.
