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.

What is a mockup sandbox used for in UI design iteration?▼

A mockup sandbox is an isolated, live-rendered frontend playground used to design, prototype, and iterate on UI components, eliminating the guesswork of manual hand-coding during component development.

Can I visualize different UI states like loading and error in a component preview?▼

Yes, the component preview sandbox supports state visualization for loading, empty, and error states, allowing you to design and compare multiple component variants under different UI conditions.

How do I extract real app code into a UI prototyping sandbox?▼

You can use the component extraction workflow to pull real app code into the mockup sandbox, enabling accurate iterations and side-by-side comparisons of your live UI components.

Do I need a Vite environment to run a live component preview canvas?▼

Yes, provisioning the live component preview canvas requires a Vite-based sandbox environment, utilizing iframe routes to render and display your UI mockups accurately.

What are the limitations of iterating on UI components in an isolated iframe sandbox?▼

The isolated iframe sandbox requires a Vite-based environment and specific directory structuring, meaning components must be extracted into the sandbox to accurately compare variants against real app code.
