FAQPage Schema

How do I prototype UI components without affecting the main application?▼

An isolated Vite-based sandbox enables prototyping UI components without affecting the main application by serving iframe previews on a live canvas, ensuring safe experimentation and repeatable results.

How does an iframe sandbox help with UI design iteration?▼

An iframe sandbox helps with UI design iteration by embedding isolated web component previews directly on the canvas, allowing you to compare multiple variants and responsive states side-by-side without risking the main app.

Can I compare multiple UI variants on a live canvas during prototyping?▼

Yes, you can compare multiple UI variants on a live canvas by orchestrating structured preview states, allowing DESIGN subagents to coordinate and display different component variations simultaneously for rapid iteration.

Does the mockup sandbox require Vite for local web component previews?▼

Yes, the mockup sandbox requires Vite for local web component previews, using it as the technical foundation to serve isolated iframe previews at a dedicated route on the canvas.

How do I graduate a prototyped mockup into my main application code?▼

You graduate a prototyped mockup into your main application by using companion workflows designed to extract the iterated UI components from the sandbox and integrate them seamlessly into the main app structure.
