# Rockbox Daemon

> A modern wrapper around the Rockbox audio engine, exposed over gRPC, GraphQL, HTTP and MPD — with multi-room AirPlay, Snapcast, Squeezelite, Chromecast and UPnP.

Rockbox Daemon is a modern take on the [Rockbox](https://www.rockbox.org) open-source
audio player firmware. The Rockbox C engine — gapless playback, DSP, 20+ codecs,
and the tag database — in a single binary (rockboxd) that expose **gRPC**,
**GraphQL**, **HTTP** and **MPD** APIs, add a **Typesense**-backed search engine,
and stream audio to **AirPlay**, **Snapcast**, **Squeezelite**, **Chromecast**
and **UPnP** receivers.

Everything ships as a single binary called `rockboxd` (all codecs statically linked).

## Status

Rockbox Daemon is actively developed. The audio engine, library, search, MPD
server and the AirPlay / Snapcast / Squeezelite / Chromecast sinks are all
production-ready. Mobile clients and Wasm extensions are on the roadmap.
