How it Works
This tool renders your URL across three distinct device profiles simultaneously. This allows you to visually audit your site's responsive behavior side-by-side without manually resizing your browser.
Key Features:
- Side-by-Side Comparison: View Mobile, Tablet, and Desktop layouts at once.
- High Fidelity: Renders using standard WebKit/Blink standards.
- Design Audits: Perfect for checking if hero images or typography break on smaller screens.
Note on Permissions
Some websites (like Facebook or Amazon) have security policies (X-Frame-Options) that prevent them from being displayed in a previewer. For those sites, we recommend using our dedicated browser extension.
