Introduction

SnapDog is a premium, open-source multi-room synchronized audio controller that runs as a single binary on Linux, macOS, and Windows. It embeds a completely rewritten Snapcast compatible server in pure Rust, runs AirPlay and Spotify Connect receivers per zone, streams from Subsonic/Navidrome media servers, plays internet radio, and bridges everything tightly to MQTT and KNX.

Architecture Overview

SnapDog’s core is designed for low latency, lossless synchronization, and robust smart home integrations.

Key Features

Embedded Snapcast Server

Reimplemented in pure Rust via snapcast-rs. Supports lossless sync playback across multiple rooms.

Built-in DSP & EQ

Per-zone parametric equalizer and Spinorama speaker correction profile database (over 1,000+ speakers).

Smart Home Bridges

Zero-config Home Assistant integration via MQTT and programmable KNX client/device modules.

SnapDog OS

A custom, minimal Buildroot Linux image that turns any Raspberry Pi into a dedicated high-fidelity receiver.
