Your storefront loads dozens of files on every page, but you can't tell which app put each one there. PageLens scans your store in a real browser, names every script's owning app, shows your speed score frame by frame, estimates the gain of removing any app, finds files left behind by uninstalled apps, and flags off-screen images. Every fix opens directly in Shopify's theme editor; PageLens never touches your theme.

• Scan your live storefront in a real browser and see every file it loads.
• See which app each script on your storefront comes from.
• Get a real speed score for mobile and desktop, refreshed on every scan.
• Find theme files left behind by apps you've already uninstalled.
• Estimate time saved by removing any third-party app before you do.
