Could you build this?
Partial The matchmaking UI is simple, but real-time audio for random pairing needs WebRTC infrastructure (TURN servers, signaling, scaling) and serious moderation and safety systems for strangers.
What it would actually take: The stack is a WebRTC client with a signaling server, a matchmaking queue, and TURN/SFU infrastructure for NAT traversal and scale. The hard parts are reliable low-latency audio across networks and abuse prevention for anonymous voice calls, including reporting, automated detection, and trust-and-safety staffing. That requires experienced real-time backend engineers and ongoing operational work.
