Overview
即时设计 (JS.Design) is a cloud-native collaborative design platform built for modern product teams. From interface wireframes to fully polished UI, it provides an all‑in‑one workspace where designers, product managers, and developers can work together in real time. With powerful vector editing, responsive layout, component libraries, and design systems, teams can create consistent experiences across web, mobile, and multi‑terminal products.
Designed with Chinese teams in mind, 即时设计 offers fast performance in the browser, smooth collaboration over domestic networks, and interfaces that match local workflows. Multi‑cursor editing, comments, and version history make it easy to explore ideas, review proposals, and trace every change without losing context. Components, styles, and tokens help you maintain a single source of truth for your brand and product UI.
For handoff, developers can inspect designs, view specs, and export assets directly from the same file, reducing communication costs and rework. Flexible permissions keep your projects secure while making it simple to share with stakeholders. Whether you are building a new SaaS product, refreshing a mobile app, or standardizing design language across a large organization, 即时设计 helps your team prototype, iterate, and ship high‑quality interfaces faster—without switching between multiple tools.
