FAQ
Do I need to install a Shopify app?
No. You just paste your store URL. The scanner runs externally using Lighthouse and public asset analysis — no app install or API keys needed to get started.
How is this different from Google PageSpeed Insights?
We go beyond generic scores. The scanner identifies specific Shopify theme files, app scripts, and liquid-rendered elements responsible for slowdowns, with Shopify-specific fix guidance.
Can I scan competitor stores?
Yes — any publicly accessible Shopify storefront can be scanned. Great for benchmarking your store against top performers in your niche.
