One small, static binary per device — pure Go, no runtime, no dependencies. Pick the path that fits your setup; every one ends with a node on your network in a few minutes.
Grab the build for your hardware, unpack it, and run it. No flags required — it picks sensible defaults, finds your audio device, and joins the cluster on its own. That’s the whole setup.
tar -xzf ondaire-linux-arm64.tar.gz
./ondaireThe quickest way onto a Linux box: a guided one-liner. It detects your OS and CPU, downloads the matching build, then walks you through the optional extras — Spotify Connect and a boot-time service — and sets them up. Installs into /usr/local/lib/ondaire; re-run any time to update.
curl -fsSL https://ondaire.rand0m.me/get.sh | sudo bash
Run a master on a NAS or server: mount your music library read-only and serve it to your players, with Spotify Connect built in. The container sources and controls audio; output happens on your players, not in the container.
docker run -d --network host \
-v /srv/music:/media:ro \
-v ondaire-data:/data \
harbor.rand0m.me/public/ondaire:latest --name living-room
--network host is required. Players discover the master over mDNS and go-librespot advertises Spotify Connect over zeroconf — multicast doesn’t cross Docker’s bridge network.
Want ondaire to come up with the machine and restart on failure? The guided installer offers to write and enable a systemd service for you — no hand-editing unit files. Choose “yes” when it asks, or set it up later following the user guide.
Turn a PSRAM-equipped ESP32 + an I2S DAC into a real ondaire player: it shows up in the cluster, joins any group, and plays in lock-step like every other room — flashed straight from your browser, no toolchain. Tested on the ESP32-S3 Super Mini and Waveshare ESP32-S3-Zero with a PCM5102A DAC.
