Instantly X-ray any Shopify store: identity, catalog, tech stack, SEO, social & a maturity score. No login. No API keys. No setup. Just click.
ShopSpy analyzes the Shopify store in your active tab using only public data — the page DOM,
the window.Shopify object, and Shopify's public JSON & sitemap endpoints. The moment you land on a
Shopify store, the toolbar icon lights up green; click it for a full intelligence report in under a second.

- Catalog stats sample up to 500 products (
products.json, 2×250) for speed; total counts come from the sitemap and are accurate for the whole store. - Password-protected or heavily bot-blocked storefronts may expose less data.
- Theme version is best-effort — Shopify doesn't always expose it publicly.
- Everything runs locally in your browser. ShopSpy makes no external calls beyond the store you're viewing.
Built with vanilla JS · Manifest V3 · zero dependencies — because good tools shouldn't need a build step.
