What is OpenJam and how does it work?

OpenJam is a real-time collaborative music listening platform that lets you create virtual rooms, invite friends, queue YouTube music, and listen together in millisecond-accurate sync across all devices.

Is OpenJam completely free to use?

Yes, OpenJam is 100% free with no subscription fees, hidden paywalls, or feature restrictions. You can create unlimited public or private listening rooms.

Can I use OpenJam as a free Watch2Gether or Spotify Jam alternative?

Yes! OpenJam is the ideal free alternative to Watch2Gether, JQBX, and Spotify Jam. Unlike Spotify Jam which requires Spotify Premium subscriptions for all participants, OpenJam allows anyone to stream and sync YouTube music together for free with no subscriptions required.

Do I need a Spotify or YouTube account to listen?

No, anyone with the room link can join instantly as an anonymous guest without creating an account or logging into third-party services.

How does real-time music synchronization work on OpenJam?

OpenJam uses WebSocket NTP-style clock synchronization to measure network latency and calculate clock offsets, ensuring every listener in the room hears the exact same audio beat simultaneously.

What is Stage Mode with synchronized karaoke lyrics?

Stage Mode provides a full-screen, ambient visualizer featuring dynamic album artwork glow and real-time kinetic karaoke lyrics synchronized to the exact millisecond of playback.

Can I import playlists from Spotify or YouTube into OpenJam?

Yes! OpenJam supports instant playlist importing from public Spotify and YouTube URLs, automatically loading all tracks directly into your live room queue or personal playlist.

Can I use OpenJam on my mobile phone as a PWA?

Absolutely. OpenJam features a responsive mobile interface with touch controls and Progressive Web App (PWA) support so you can install it on iOS, Android, macOS, and Windows.
