Can I check a Shopify store's tech stack without a Shopify account?

Yes. All detection signals come from public HTTP responses. No Shopify account, no Partner access, and no store login is required. Any public store URL can be scanned.

How do I find out which theme a Shopify store is using?

A tech stack checker reads the stylesheet link in the page HTML, which includes the Shopify CDN path with a theme identifier. The theme name is embedded in or derivable from this path. Some themes are also identifiable by their CSS class naming conventions.

Can the checker identify the Shopify plan the store is on?

Not reliably. Shopify plan signals are limited. Shopify Plus stores are identifiable when they use Shopify Scripts (which affects checkout behavior) or when they have a custom checkout domain, but basic, Shopify, and Advanced plans are not distinguishable from front-end signals alone.

Will the checker detect Yotpo or Stamped reviews apps?

Yes. Both Yotpo and Stamped load external scripts from their own domains (cdn.yotpo.com and stamped.io CDN), making them detectable whenever a store uses them on a page that loads review widgets.

Can the checker detect subscription apps like Recharge or Bold Subscriptions?

Yes, on pages where those apps load front-end scripts. Recharge and Bold Subscriptions load scripts on product and cart pages when subscription products are present, making them detectable from those page URLs.

What is a headless Shopify store and how does detection differ?

A headless Shopify store uses a custom front-end framework (Next.js, Nuxt.js, React) instead of Shopify's Liquid theme system, connecting to Shopify via the Storefront API. Detection shows the front-end framework rather than a Shopify theme name, and the Shopify CDN may not be the primary asset source.

Does every Shopify store use Shopify's CDN?

Yes, for theme assets. All Shopify theme files are served from Shopify's CDN by default. Some stores add a Cloudflare layer in front of the Shopify CDN for additional performance and security, which shows up as Cloudflare headers in the HTTP response.

Can I detect which payment processor a Shopify store uses beyond Shopify Payments?

Partially. Alternative payment processors that load front-end scripts on the checkout page (PayPal, AfterPay, Klarna, Shop Pay) are detectable from checkout page HTML. Stores using only Shopify Payments show fewer external payment processor signals.

How do I check a Shopify store that requires a password to access?

Password-protected Shopify stores serve a login page rather than the full storefront. Detection from the password page is limited to confirming the site runs on Shopify and reading any signals present in the login page HTML.

Is tech stack detection on Shopify stores legal?

Reading publicly available HTTP responses from a public URL is standard internet behavior and is used by search engines, SEO tools, and security scanners. Detection does not bypass any access controls and does not read private store data.

Can the checker detect if a Shopify store uses Shopify Markets for international pricing?

Not directly from a standard URL scan. Shopify Markets affects server-side pricing logic and currency display, but does not consistently produce a unique front-end signal distinguishable from standard Shopify.

How current is the theme detection database?

Theme detection relies on Shopify's consistent CDN URL structure for the theme identifier plus CSS class signatures for specific paid themes. The CDN structure is stable across Shopify versions; specific theme signatures are updated as major themes release updates that change their class naming.

What passive detection reveals about a Shopify store's theme, apps, and infrastructure — from a public URL

Shopify stores expose a consistent set of technology signals through their HTML source, HTTP headers, and asset URLs. Unlike self-hosted platforms, Shopify's architecture is predictable — the CDN is always Shopify's own, the asset URL structure follows a fixed pattern, and the theme files are always served from Shopify's content delivery network. This makes Shopify theme and app detection more reliable than on custom-hosted platforms.

What Makes Shopify Detection Different from Other Platforms

Shopify is a hosted platform, which means every store runs on Shopify's infrastructure rather than a customer-managed server. This creates a different detection profile than WordPress or custom-built sites. The CDN is always Shopify's own (cdn.shopify.com), so asset URL structure is predictable. The theme is always rendered server-side by Shopify's Liquid templating engine, and the theme name appears in the stylesheet link path. The checkout page is always on checkout.shopify.com (for stores not using Shopify Plus with a custom checkout).

This predictability makes Shopify detection more reliable in some ways (theme name is almost always readable) and less informative in others (the underlying server and hosting environment are always Shopify's — there is no meaningful hosting detection).

Theme Detection on Shopify

The active Shopify theme is readable from the stylesheet link in the page HTML. Shopify serves theme assets from a URL path that includes the theme identifier — a string like cdn.shopify.com/s/files/1/0000/0000/t/1/assets/theme.css identifies the theme by the directory segment. Some paid themes from the Shopify Theme Store include their name in the CSS class naming convention, making identification more specific.

Headless Shopify stores (built on Next.js, Nuxt.js, or custom React frontends using the Storefront API) do not use the Liquid theme system and will not show a Shopify theme name. The tech stack checker identifies these as headless implementations and shows the front-end framework instead.

App Detection — What Front-End Apps Expose

Shopify apps that add front-end functionality load their scripts from external domains or from Shopify's app proxy, and these script sources are visible in the page HTML. Common detectable apps include review platforms (Stamped, Yotpo, Judge.me — each with distinctive script domains), loyalty programs, live chat tools, upsell widgets, and subscription billing platforms. Apps that operate entirely within the Shopify admin panel or process webhooks server-side have no front-end footprint.

The checkout page typically reveals additional apps not visible on product pages — post-purchase upsell apps, customer experience tools, and subscription management platforms often load their scripts on the order confirmation or cart page specifically.

Shopify Technology Signals by Detection Source

All signals are readable from public page responses. No store credentials or Shopify Partner access required.

Signal Source	What It Reveals	Notes
Stylesheet link href in page HTML	Active theme name and variant	Highly reliable — Shopify embeds theme identifier in asset path
External script sources in HTML	Third-party apps (reviews, chat, loyalty, upsell)	Visible only for apps loading front-end assets
HTTP headers (CF-Ray, CDN signals)	Cloudflare or additional CDN layer on top of Shopify	Shopify's own CDN is baseline; some stores add Cloudflare
HTML structure and Liquid comments	Shopify Liquid theme vs. headless storefront	Headless stores lack Liquid template markers
Script sources on cart/checkout pages	Payment apps, subscription platforms, upsell tools	More app signals visible on transactional pages than product pages
