Responsive design testing used to mean juggling physical devices, browser resizing, and remote testing services. Lodos Simulator Panel consolidates all of this into one interface — see your website on a phone, tablet, and desktop at the same time, with real DevTools alongside each view.
Simultaneous Multi-Device Preview
Load any URL and instantly see it rendered across multiple device profiles side by side. Supported profiles include:
- iPhone 14 / 15 Pro (390×844, 393×852)
- Samsung Galaxy S23 (360×780)
- iPad Air and iPad Pro (820×1180, 1024×1366)
- Standard laptop (1280×800, 1440×900)
- Full desktop (1920×1080)
- Custom dimensions — enter any width and height
Built-In DevTools
Each device view comes with integrated DevTools panels:
- Console — see JavaScript errors and logs per device
- Network — inspect requests and response times
- Storage — view localStorage, sessionStorage, and cookies
- Performance — measure load time and render performance
Accessibility and Contrast Checking
The built-in contrast checker highlights text elements that fail WCAG AA/AAA contrast requirements. The touch target validator marks interactive elements smaller than 44×44px — the minimum recommended touch target size for mobile usability.
Screenshot Capture
Capture full-page or viewport screenshots of any device view with one click. Screenshots can be saved directly to Lodrive or shared via Social Hive for design reviews — no third-party screenshot tool needed.
Who Uses Simulator Panel
- Frontend developers verifying responsive breakpoints during development
- QA engineers testing across device profiles before release
- Designers reviewing how layouts render on real screen dimensions
- Product managers checking feature implementations without needing physical devices
