FAQPage Schema
How do I prototype UI components with live previews without affecting the main app?▼

An isolated Vite-powered sandbox canvas renders UI components in iframe routes for live previews. This self-contained environment allows you to iterate on UI variants and responsive states without integrating with or affecting your main application.

What is the best way to compare UI variants and responsive states during mockup prototyping?▼

The best way to compare UI variants and responsive states is using a dedicated mockup sandbox with a component registry. It supports structured workflows to build, validate, and present mockup artifacts across different viewports side-by-side.

How do I start building a mockup component in a Vite sandbox?▼

To start building a mockup component, create a React component file under the artifacts/mockup-sandbox/src/components/mockups/ directory. Once created, start the mockup server and embed the generated preview onto your canvas.

Can I use iframe embedding to preview UI mockups across different viewports?▼

Yes, iframe embedding is fully supported for previewing UI mockups across different viewports. The sandbox uses iframe routes to render components, enabling you to validate responsive states and design tokens before integration.

Does this mockup sandbox support orchestration for complex UI prototyping tasks?▼

Yes, the mockup sandbox supports subagent orchestration and companion skills for complex UI prototyping tasks. These workflow patterns help manage and graduate mockup artifacts when building elaborate component structures.
