What this tool does

Detect what theme any Shopify store uses

Paste any Shopify storefront URL. The detector identifies the theme name, version, and any theme app extensions installed - useful when scoping a competitive analysis, researching what's working in your category, or vetting a freelance theme dev's prior work.

How to use it

One input, one output

  1. 1Paste the storefront URL (e.g. brand.com or brand.myshopify.com).
  2. 2Click Detect. The check runs in 2-4 seconds.
  3. 3Read the theme name + version. Free Shopify themes (Dawn, Sense, Refresh, etc.) and paid themes (Impulse, Prestige, Symmetry, Empire, etc.) are both detected.
  4. 4Note any theme app extensions visible in the storefront - good signal for what apps the store uses.

Merchant tips

How merchants actually use theme detection

Use it to research competitors - see which paid themes high-performing stores in your category run, then evaluate whether the same theme would work for you.
Vet a freelance theme developer's portfolio. Do their claimed past projects actually run the theme they claim to have customized?
Identify storefronts running outdated theme versions (security + performance signal). Outdated themes are often slower and may have known bugs.
Pair theme detection with the Sales Activity Estimator to understand both what a store sells and what it runs. Useful for partnership prospecting.

Frequently asked questions

How does it know which theme a store uses?
Shopify themes leave their name and version in the storefront's public markup and asset paths. The detector reads those and matches them.
Can it find the version as well as the theme?
Usually yes. The version matters because theme updates change what an app can hook into and what checkout features the store supports.
Why does it say the theme is customized?
Heavily edited themes stop matching the published version cleanly. That is normal for an established store, and it is worth knowing before you plan a migration.
Does it work on stores that are not on Shopify?
No. It is a Shopify theme detector, and a non-Shopify storefront will simply come back with no match.
