Pulse — Store Speed

Pulse runs Google Lighthouse and PageSpeed Insights on your storefront and turns the results into a simple performance score and Core Web Vitals (LCP, CLS, INP). Instead of raw audit data, it gives you a prioritized list of fixes in plain English, with Shopify-specific tips for images, apps, and theme code. Test any page on mobile or desktop, and track your scan history over time to see whether your changes actually made the store faster.
