Plays local and remote audio files through ffplay or afplay. The reference backend: no credentials, no network, no accounts.

Run an adapter as a subprocess speaking newline-delimited JSON, so backends can be written in any language.

Read and control whatever macOS is playing — a browser tab, VLC, Doppler, anything that publishes to Control Center.

Play audio through a media element you control — in a browser, an Electron renderer, or a webview. Works across a process boundary too.

Play Spotify through the desktop app on macOS with no credentials, or through the Web API with a token your host already holds.

Play Apple Music through the Music app on macOS — no credentials, and it can search your library by title.

Source-agnostic media queue and playback runtime. Zero dependencies, no I/O.
