PageLens identifies every app loading on your Shopify storefront and shows exactly what's slowing down your site speed. Scan your store in a real browser to see which app added each script and file. Get accurate mobile and desktop speed scores with every scan. Measure the impact each app has on your page performance and discover leftover theme files from apps you've already removed. Preview potential speed improvements before making any changes to your store, so you know exactly what to fix for better storefront performance.
