Every release has a build per system on the releases page. Spytify also needs ffmpeg, which encodes the files.

Linux

macOS

Windows

The Windows build is a first draft, being tested.

Choose the application

Official builds come with a default application. In a build of your own, open Settings > App > Advanced > Player, enter the application’s name (its executable, without .app or .exe), and press Save and restart spytifyd. The command line page lists the variables behind it.
