Free Tool

Shopify theme detector

Paste any store URL. We identify the eCommerce platform, the active theme, and the apps installed — Shopify, BigCommerce, Magento, WooCommerce, SFCC, Squarespace, Wix and more. Free, no signup, results in seconds.

Apex domain only — e.g. example.com, not /products/foo. Detection takes 2-5 seconds.

How the detection works

A reliable platform fingerprint comes from three independent signal classes. We run all three on every request and report the one with the strongest evidence — high-confidence results require an authoritative signal (a JavaScript global, a CDN host, or a platform-specific cookie), not just a generator meta tag, because generator tags are trivial to leave stale across a migration.

  • JavaScript globals. Authoritative when present. Shopify exposes Shopify.theme, Shopify.shop, and the checkout API token; BigCommerce sets BCData; Squarespace publishes Static.SQUARESPACE_CONTEXT. Heavily customised themes or headless front-ends sometimes strip these.
  • Asset CDN hosts. The hardest fingerprint to mask: even if a store hides its platform in markup, cdn.shopify.com, cdn11.bigcommerce.com, demandware.static, static1.squarespace.com, and static.parastorage.com still resolve to platform infrastructure.
  • Cookies and headers. _shopify_y, x-shopid, the Demandware Sites pipeline path, and the Shopify powered-by header are all server-controlled, so they survive most theme-level customisation.

We also surface the third-party apps we recognise — Klaviyo, Recharge, Yotpo, Judge.me, Gorgias, Algolia, Nosto, and others — which makes the tool useful when sizing up a store for a replatform conversation.

What this tool does not tell you

We can identify the platform and the theme. We cannot tell you whether the theme is customised (most commercial Shopify themes get heavy modification), how much the build cost, or which checkout extensions are wired up server-side. For that level of audit we run a full migration discovery — see our Shopify Plus pricing breakdown and the composable commerce piece for the questions that matter beyond detection.
