Free Responsive Website Audit

Grade your site's responsiveness in seconds

Paste any URL for an automated audit at four breakpoints — mobile, tablet, laptop, and desktop. We check horizontal overflow, the viewport meta tag, touch target sizes, iOS input zoom, missing image alt text, and JavaScript errors, detect the platform the site is built with (WordPress, Shopify, Wix, Next.js, and more), and suggest fixes tailored to it. Download the whole thing as a PDF report. Free, no signup.
