FAQPage Schema

How do I preview UI components on a canvas for rapid prototyping?▼

To preview UI components on a canvas for rapid prototyping, this tool runs a vite dev server that renders components in real-time, allowing you to design, iterate, and compare web UI variants directly.

Can I use Tailwind and shadcn/ui for responsive design previews?▼

Yes, you can use Tailwind and shadcn/ui for responsive design previews. The sandbox requires both frameworks to render components and enables you to visualize layouts across mobile, tablet, and desktop devices.

What is the best way to compare UI design variants side-by-side?▼

The best way to compare UI design variants side-by-side is by parallelizing work with DESIGN subagents, which allows you to explore multiple visual alternatives like dark versus light themes simultaneously on the canvas.

How do I prototype different component states like loading and error?▼

You can prototype different component states like loading and error by rendering your web UI components on the canvas, which supports previewing various states to test user experience flows comprehensively.

Do I need a vite dev server to render and iterate on web UI components?▼

Yes, you need a vite dev server to render and iterate on web UI components. It provides the local development environment necessary to support real-time rendering and rapid UI prototyping within the sandbox.

Are there limitations when using cartographer for component rendering?▼

Cartographer is required alongside Tailwind and shadcn/ui for component rendering and styling, meaning your UI prototyping is constrained to components compatible with this specific tech stack.
