About this app
Launched: Feb 24, 2026, 12:00:00 AM
SpeedScope monitors your store's speed, finds slow apps, fixes performance issues automatically.
SpeedScope helps Shopify merchants identify exactly what is slowing down their store. It runs Core Web Vitals audits powered by Google PageSpeed, scans every installed app to measure its script size and load impact, and detects ghost scripts left behind by uninstalled apps. The app provides a clear performance grade for each third-party app on your store, prioritized recommendations, and automated fixes like lazy loading images, deferring scripts, and adding preconnect hints directly.
- Core Web Vitals monitoring with LCP, INP, CLS scores and actionable fix tips.
- App impact scorecard showing which installed apps slow down your storefront.
- Ghost script detection finds and removes leftover code from uninstalled apps.
- Automated speed fixes like lazy loading, script deferral, and font optimization.
- Performance budgets and speed alerts to catch regressions before they hurt sales
