Kassette allows you to see and control what is playing in the background, currently only Spotify is supported.
(Warning, as of February 11th 2026, Spotify will limit API access to Premium accounts!)
For the Spotify backend (using their API), you currently need:
- a Spotify Premium account; free accounts cannot create apps using the developer portal!
- a Spotify developer account with an app set up
- a working internet connection
