A presentation canvas where developers can load code snippets or responsive links in framed container displays side-by-side (matching Desktop, Tablet, and Mobile viewport standards) with orientation pivoting, customizable chassis structures, and adjustable scaling factors.

How It Works

  1. Drag the visual border sliders of the simulation stage to resize viewports.
  2. Click standard device buttons to view layouts at specific resolutions.
  3. Inspect how elements reposition, columns shift, and menus adapt live.

Frequently Asked Questions

How does the sandbox bypass x-frame constraints?

By offering a dual-mode engine! In Code Sandbox mode, we use HTML string dynamic allocation inside direct iframe srcDoc properties. This isolates scripts and layout rendering completely inside your active browser with 100% security.

Can I test my local server paths like localhost:3000 here?

Yes. If you switch the presenter to Host URL and your local backend or preview environment is running on your machine, it will display correctly inside the frames.
