SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The mockup sandbox provides an isolated, live-rendered frontend playground that lets you design, prototype, and iterate on UI components directly on the workspace canvas, eliminating the guesswork of manual hand-coding.

Core Features & Use Cases

  • Isolated Vite-based sandbox that serves live component previews via iframe routes.
  • Supports design variants, responsive previews, and state visualization (loading, empty, error).
  • Enables component extraction workflow to pull real app code into the sandbox for accurate iterations and side-by-side comparisons.

Quick Start

Start the mockup sandbox server and begin adding mockup components.
