About YunYu
We believe customer service work shouldn't be confined to basic chat widgets. YunYu redefines online customer service with desktop-grade operation experience, giving every service team a professional-grade platform.
Our Story
YunYu was born from a simple observation: most online customer service tools on the market, whether in interface experience or feature depth, are stuck at the "web chat widget" stage. Customer service agents switch between narrow conversation windows all day — inefficient and frustrating.
We decided to change that. Using a Mac-style desktop UI design, we gave the service workstation professional interaction capabilities like window dragging, Dock shortcuts, and multi-window parallelism. The backend is built on Go, supporting thousands of concurrent connections on a single machine without complex microservice architecture.
From day one, we've maintained a three-terminal independent architecture — agent, merchant, and admin terminals each run independently. This isn't feature bloat — it's about giving every role the interface that suits them best.
Tech Architecture
Core Capabilities
Not just another live chat tool — a platform that redefines how customer service works
Desktop Workstation
Mac-style desktop UI with multi-window management, Dock shortcuts, and drag-to-arrange — 40% efficiency boost. An operation experience traditional web chat widgets can't match.
Three Independent Terminals
