ShopCast is a platform for live-stream shopping. It unifies low-latency live streaming, real-time chat, a live cart, and instant payments into a single platform that withstands 10,000 concurrent viewers.
“The gap between streaming and buying,” “peak-time real-time load,” and “inventory consistency during live” — Retail Live Inc., the story of launching a new platform, built together in-house from scratch in 12 months.
A live-commerce operator that connects brands in apparel, cosmetics, lifestyle goods and more with viewers through live streaming. Hosts showcase products while viewers comment, ask questions, and buy on the spot — an interactive, two-way shopping experience.
A “watch-and-buy” experience demands a single platform that binds together low-latency streaming, chat for massive concurrent connections, an inventory-consistent cart, and instant payments. Building it in-house from scratch was the starting point of the business.
Unlike ordinary e-commerce, unless you can handle the live-specific load of viewing, conversation, and buying all spiking at once, neither the experience nor the revenue holds up.
React front end, low-latency live streaming with Agora, real-time sync of chat and the live cart via NestJS WebSocket + Redis Pub/Sub, unified product/order/inventory management with Laravel, and instant payments with Stripe and GMO — a real-time platform built fully in-house from scratch to withstand 10,000 concurrent viewers.
