Could you build this?
Partial Chat, room creation, and a basic shared player are vibe-codeable, but keeping video playback synchronized across multiple platforms and running low-latency voice rooms needs real-time infrastructure. Those pieces are doable with managed services but are hard to get right and expensive at scale.
What it would actually take: Use WebSockets or a managed realtime service for playback state and chat, and WebRTC via a provider such as LiveKit or Agora for voice. Synchronization needs a host-authoritative clock with drift correction, and embedded players for services like YouTube have restrictions. The hard parts are latency-tolerant sync across players and the cost and reliability of media servers at scale, which call for realtime infrastructure experience.
