Spotycast is a lightweight, self-hosted Docker bridge that exposes Spotify connect playback as a standard HTTP/Icecast stream. It lets you reuse the same DAC and audio chain across systems like Roon, Volumio, Moode or Lyrion without adding extra Spotify hardware to play lossless quality (where available). Designed for stability and predictable playback in mixed audio setups where Connect or AirPlay can be fragile.
