Preview your website across 20+ real device dimensions. Our Device Friendly Test shows how your site looks on iPhone, iPad, MacBook, and desktop monitors side-by-side — with realistic device frames and accurate viewport sizes. No browser extensions or DevTools needed.
"Mobile-friendly" has become table stakes for SEO and user experience, but many sites that look responsive on the surface have issues that only show up on actual devices — tiny tap targets, viewport problems, unreadable text. This tool analyzes your page for the specific things Google checks and gives you actionable results, not just a pass/fail.
Why Test Device Friendliness?
Real Device Dimensions
Preview your website at exact device resolutions — iPhone 15 Pro (393×852), iPad Air (820×1180), MacBook Air (1440×900), and Full HD monitors (1920×1080). See exactly what your visitors see on their actual devices.
Side-by-Side Comparison
View your website on mobile, tablet, laptop, and desktop simultaneously. Toggle devices on and off to focus on specific breakpoints. Identify layout issues across screen sizes at a glance.
No Extensions Required
Unlike browser DevTools responsive mode, this tool previews your live production URL in real device frames. No browser extensions, no installs — just enter your URL and see results instantly.
SEO-Critical Testing
Google uses mobile-first indexing, meaning it primarily crawls the mobile version of your site. A poor mobile experience directly impacts your search rankings. This tool helps you catch issues before Google does.
