Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSee which Shopify apps and scripts slow your store. LoadLess: Speed Optimize ranks script impact by app, tracks real-user Core Web Vitals (LCP, INP, CLS), estimates revenue at risk from slow pages, and delivers a theme health report with clear fixes. Defer, delay, or lazy-load chat, reviews, and marketing pixels with merchant-approved rules or one-click safe presets—no uninstalling required.
SwiftStore scans your Shopify theme and identifies every factor slowing down your store. It detects render-blocking scripts, oversized images, unused CSS, and slow third-party app scripts. Once issues are found, you can preview fixes in a safe sandbox before applying them to your live store. The app runs image compression, script deferral, font preloading, and critical CSS extraction automatically.
