Start a room, send one link, and everyone hears the same second of the same song. There's a shared queue anyone can add to, live chat, reactions, and an optional AI DJ that takes requests in plain English. It runs on a computer you already own, and your friends connect to it.
| Synced playback | A server-side clock keeps every listener on the same second. A laptop waking from sleep catches up instead of pulling the room back. |
| Shared queue | Anyone can add. Upvotes move a track one place per person, drag to reorder, vote to skip, and see who added what. |
| One-link rooms | No sign-ups for anyone. Rooms survive restarts, so a link can be your group's spot for good. |
| Chat and presence | See who's listening, typing or away. Reactions burst identically on every screen. |
| Sounds like a real app | Crossfade, volume levelling, lock-screen controls and casting to speakers. |
| Host controls | Mute or remove listeners, or make a room invite-only and approve each person. |
| Optional AI DJ | /dj add 10 rainy day songs fills the queue and introduces tracks in character. Free with Gemini or a local Ollama. |
| Built for phones | Swipeable panes, installable to the home screen, and the room takes its colour from the album art. |
Desktop (easiest). Download the latest release, unzip it, and run start.bat on Windows or ./start.sh on macOS and Linux. It fetches Node if needed, opens your browser, and prints a public link you can send to anyone.
Docker (always-on box).
git clone https://github.com/SAKMZ/syncwave.git && cd syncwave
cp .env.example .env
docker compose up -d --buildLinux server (one command).
curl -fsSL https://raw.githubusercontent.com/SAKMZ/syncwave/main/scripts/install.sh | sudo bashThen open the address it prints and set an admin password at /setup straight away. Until it's set, anyone who can reach the server can claim it.
Note
On a cloud VPS, YouTube refuses most datacenter IPs, so you'll need a proxy pool or a cookies file. It's one setting in /admin; DEPLOY.md walks through it, along with custom domains, Tailscale, Railway and automatic updates.
