Device Simulation Dashboard

Preview sites on phones, tablets, and desktops.

Stop manually resizing your browser or fighting with laggy, basic iframes that fail to simulate real hardware behavior. Ultimate Device Simulator Pro is a premium, high-density development cockpit built specifically for frontend developers, UI/UX designers, and QA engineers who demand precision. Unlike generic extensions that simply change CSS widths, this extension hooks natively into the browser's underlying engine using the Chrome DevTools Protocol (CDP). It forces Chromium to render your target URL exactly as it would appear on a real mobile device, tablet, or laptop—handling native pixel densities (DPR), touch event emulation, and safe areas perfectly. 🌟 KEY FEATURES THAT SET US APART: True Hardware Virtualization: Select from an elite catalog of devices. Chromium adapts its rendering engine to emulate real Device Pixel Ratios (DPR), user-agents, and responsive viewport specs. Unified interaction Sync Engine: Scroll, click, hover, and type in one simulated device viewport, and watch your actions mirror perfectly across all other active devices in real-time. Zero lag, zero layout alignment drift. Infinite Layout Zoom Control: Scale your entire multi-device workspace smoothly from 50% to 150% via high-performance hardware acceleration without losing text crispness or distorting layout components. Pure CSS Geometric Device Bezels: Ditch ugly, heavy image mockups. Devices are rendered using precise geometric CSS frames displaying custom rounded corners, notches, and hole-punch camera zones to respect real safe-area paddings. Zero CSP or Iframe Blockages: Built-in local request processors safely strip out restrictive X-Frame-Options and strict Content Security Policies (CSP) header constraints. Debug any live production system, corporate intranet, or localhost build with 100% compatibility.
