Does this Shopify store use Klaviyo?

Paste any Shopify URL. We scan the storefront and tell you if Klaviyo is installed — plus a list of every other app the store runs.

Cold scans take ~10 seconds. Results are cached — re-checks are instant.

How it works

Single-purpose. Honest signal.

This tool answers one question. Want to know which ESP a store actually uses, get notified when they swap, or see the whole tech-stack at once? That's the paid product.

1. Paste a Shopify URL

We normalize the domain and validate it's a public host. Works on any Shopify store globally.

2. We fingerprint the ESP

First scan ~10 seconds. We check Klaviyo's loader scripts, event-tracking calls, and form integrations. Subsequent checks are cached.

3. Yes/No + the full stack

You get a binary Klaviyo verdict plus the rest of the installed app stack — Recharge, Gorgias, Yotpo, you name it.
