About

Stop wondering if your site looks right. Know it does.

Stop resizing your browser window over and over. ScreenLab lets you view any webpage across multiple device sizes simultaneously — no more guesswork, no more missed breakpoints.

🎯 One Click. Every Screen.
Toggle ScreenLab and instantly see your site rendered across phones, tablets, and desktops side by side. Test responsive layouts in real-time without leaving your browser.

📱 Pixel-Perfect Device Presets
iPhone, iPad, Android, MacBook, 4K monitors — all the devices your users actually use. Pre-configured viewport sizes so you can test what matters.

✨ Custom Viewports, Your Way
Need a specific screen size? Create unlimited custom viewports. Save them for quick access across all your projects.

🔒 Lock Height Mode
Keep all screens contained within your viewport, or unlock to see full-page scrolling behavior. You control the view.

🔄 Synchronized Scrolling
Scroll once, scroll everywhere. All viewports stay perfectly in sync so you can compare sections across every breakpoint instantly.

📸 One-Click Screenshot Export
Capture all viewports at once and download as a ZIP. Perfect for design reviews, client presentations, or QA documentation.

🌙 Dark Mode Built In
Easy on the eyes during late-night debugging sessions. Toggle between light and dark themes instantly.
