Shopify App Detector
Paste a store address and see which Shopify apps it runs. Free, no sign-up.
Trying to find out what apps a Shopify store is using? Paste the store address above. Apps that touch the storefront leave their traces in the page every shopper loads — scripts, pixels and asset hosts — and we read them from that one public page.
It is the fastest way to see which reviews app, upsell app or email tool a competitor runs, and the theme comes back alongside at no extra cost. If you have ever wanted to know what a store is built with before a sales call, this is that answer.
Be aware of the honest limit: “none detected” is not “none installed”. Apps with no storefront footprint — shipping, accounting, back-office — are invisible from outside, and about one store in five looks empty for exactly that reason.

What people do with the answer

- Agencies audit a client stack before migrating or rebuilding it.
- Merchants see what stores you admire have chosen to install.
- Sellers qualify a lead by what it already runs before you call.
What it can and can’t see
Detected
- Apps with a theme extension — named directly
- Apps registering a web pixel
- Apps injecting a script tag — identified by vendor
- Store type: native, Buy Button or headless
Not detected
- Apps with no storefront footprint — shipping, accounting, back-office
- App version, install date or plan — never exposed publicly
- Anything behind a login
This is why we report “none detected”, never “none installed”.
How the detection actually works
A Shopify store serves the same public homepage to everyone, and that page carries traces of the apps running on it. Apps that add storefront functionality ship assets from Shopify’s CDN under their own name. Apps that track behaviour register a web pixel. Older apps inject a script tag pointing at their vendor’s domain. The detector reads that one page and collects all three.
It also reads the store’s own theme declaration, so you get the theme alongside the apps. If the theme is the part you care about, the Shopify Theme Detector answers that question on its own and tells you whether the theme came from the Theme Store.
What it deliberately does not do is guess. An app that registers a pixel but no readable name is reported as an unresolved ID rather than matched to a plausible vendor, because there is no public registry mapping those IDs and a confident wrong answer is worse than an honest gap.
Why a store can show zero apps
Roughly one Shopify store in five shows none. That is usually not a store running nothing — it is a store whose apps have no storefront footprint at all:
- Shipping and fulfilment tools that work behind the checkout
- Accounting, tax and inventory sync
- Helpdesk and back-office apps staff use, not customers
None of those touch the page a visitor sees, so no public method can find them. This is why the result says “none detected”, never “none installed”.

How does the Shopify app detector work?
It reads the store’s public homepage once and looks for four signals: theme app extension assets served from Shopify’s CDN, registered web pixels, scripts injected by older apps, and the store’s own Shopify identity. No login, no account access, and nothing that isn’t already served to any visitor.
Is it free?
Yes. No sign-up, no credit card, no email required.
Why does it say “no apps detected” for a store I know uses apps?
Apps with no storefront footprint — shipping, accounting, back-office tools — leave no trace on the homepage, so they cannot be seen this way. About one Shopify store in five shows zero apps for this reason. “No apps detected” is never the same as “no apps installed”.
Can it detect every app?
No. Apps that register a web pixel are detected but sometimes identifiable only by a numeric ID, because there is no public registry mapping those IDs to app names. Those are reported separately rather than guessed at.
Does it detect the theme as well?
Yes — the theme is read from the same page, so it comes back with the apps at no extra cost. If the theme is what you are after, the Shopify Theme Detector answers that on its own and also tells you whether the theme came from the Shopify Theme Store or was built custom.
Does it work on stores that aren’t on Shopify?
It will tell you the store isn’t Shopify. It also recognises Buy Button and headless Shopify setups, which a simple “is cdn.shopify.com present” check misses entirely.
Do you store the domains people check?
We read only the public storefront, the same page any visitor receives. We do not publish or sell what individual visitors look up.
