Extension Metadata

About this extension
🚀 Stop guessing how your websites look on real hardware. CaIoT is a premium responsive testing workspace built directly into your Chrome browser—giving developers, QA engineers, and designers a physical hardware bridge that standard emulators completely miss.

🌟 WHY CAIOT IS DIFFERENT
Most testing tools just resize an iframe. CaIoT combines responsive presets, real-time diagnostic monitoring, and instant routing to an actual physical device lab.

🛠 CORE FEATURE SUITE

1⃣ MOBILE SIMULATOR & RESPONSIVE VIEW
• Preview any active tab across 27+ pre-configured mobile, tablet, desktop, and wearable viewports.
• Create completely custom viewport sizes to match specific device fragmentation.
• Rotate views, adjust layout zoom, and test safe-area layouts easily.
• Use "Live Page" bypass mode for websites that block standard iframe embedding.

2⃣ LIVE DIAGNOSTIC MONITOR
• Review browser console messages, warnings, and JavaScript exceptions instantly.
• Detect blocked API endpoints, failed network requests, and CORS infrastructure errors.
• Monitor core performance risks including Web Vitals (LCP, CLS, TTFB).
• Zero cluttered tabs—diagnostic badges count issues cleanly right over the extension icon.

3⃣ REAL HARDWARE VALIDATION
• Seamlessly jump from local visual simulation into a real physical Android device.
• Instantly route your staging link to our physical device lab to validate true chromium rendering, touch latencies, and device battery performance.
