Clarity shows you who's leaving. Superspeed stops them from leaving.
Here's the irony nobody talks about: Microsoft Clarity's tracking script degrades your Shopify store's Core Web Vitals — increasing LCP and worsening INP — which causes the drop-offs you're trying to diagnose. Superspeed gives you rage click detection, ghost checkout tracking, and funnel intelligence without adding a single millisecond to your load time.

Superspeed vs Microsoft Clarity: The Verdict
Microsoft Clarity is a generous free tool from Microsoft, and for static marketing sites it's completely reasonable. But on a Shopify storefront — where every 100ms of added latency measurably reduces conversion rate — Clarity's JavaScript payload creates a real problem. The script fires on the main thread, competes for CPU with your Add to Cart button, and worsens your Interaction to Next Paint (INP) score. You install it to figure out why people aren't converting, and it becomes part of the reason they aren't. Superspeed's telemetry runs in Shopify's isolated Web Pixel sandbox — completely off the main thread — so you get the behavioral data (rage clicks, ghost checkouts, funnel drop-offs) without any performance penalty. And unlike Clarity, Superspeed connects every session signal directly to a dollar amount.
Why you might love Microsoft Clarity
- Completely free — no budget required
- Session recordings and heatmaps are genuinely useful for UX research
- Easy Shopify installation via Google Tag Manager
Where Microsoft Clarity falls short
- Its tracking script runs on your main thread, degrading LCP and INP for real users
- Identifies problems but provides zero tools to fix them
- No revenue correlation — you see where people click, not what it costs you
- Heavy session recording causes the very poor experiences you are trying to diagnose
