Test how your website performs on different mobile devices and network conditions

Website URL

Network Condition

Emulate real mobile devices and network conditions to see how your website looks and performs on phones and tablets.

- Preview your site on iPhone, Pixel, Galaxy, and iPad
- Simulate slow networks (3G, 2G) to test loading behavior
- Capture mobile screenshots for visual QA
- Verify responsive design across different screen sizes

Over 60% of web traffic now comes from mobile devices, and Google's mobile-first indexing means your mobile site's performance determines your search rankings — regardless of how fast your desktop experience is. Testing on actual device profiles under realistic network conditions isn't optional for serious web development; it's the only way to understand what the majority of your users actually experience.

Mobile Insights emulates real device profiles — iPhone 14, iPhone SE, Google Pixel 7, Samsung Galaxy S20, and iPad Mini — under configurable network conditions ranging from 4G LTE to 2G and offline mode. It takes a full-page screenshot so you can visually verify your responsive layout, catch overflow issues, and confirm that interactive elements are properly sized. Combined with network throttling, it reveals how your site behaves when users are on a slow connection in the real world — information you can't get from a desktop browser simulation.
