See how your website looks across different devices and screen sizes.
Test on Desktop, 4K, iPhone, iPhone Pro, and iPad.
Our free responsivity checker captures real screenshots of your website across 6 different device configurations, including Desktop (1920x1080), 4K (3840x2160), iPhone (390x844), iPhone Pro (430x932), iPhone Pro Max (440x956), and iPad (820x1180). Unlike emulators that simply resize the viewport, Screenshotty uses actual headless browser rendering to produce pixel-perfect captures.
Over 60% of web traffic comes from mobile devices. A site that looks great on desktop but breaks on mobile can lose significant engagement and revenue. Responsive design testing ensures your content, navigation, and calls-to-action work across all screen sizes.
