Interactive Live Stream Demo with Red5

An interactive live stream experience combining PubNub real-time chat, betting, and product highlights with Red5 Cloud WebRTC streaming

About this demo

This live shopping demo shows how you can use PubNub's Chat SDK and JavaScript SDK with Red5 Cloud to build an interactive live shopping experience with real-time chat, in-play betting, product highlights, and WebRTC streaming.

PubNub handles all real-time data — chat, reactions, presence, betting, commentary, product events, and video sync — through dedicated channels with no custom WebSocket server required. Red5 Cloud delivers sub-second latency video so viewers see products the instant they appear and can purchase before they sell out. For customers needing full control over infrastructure, Red5 Pro provides the same performance for on-premises or self-managed deployments.
