How to check what Shopify theme a store is using
The whole check takes about ten seconds. No sign-up, no browser extension, and no limit on how many stores you look up.
- 1
Copy the store URL
Grab the address of the Shopify store you want to check. Either the custom domain (store.com) or the .myshopify.com address works — you do not need both.
- 2
Paste it into the detector
Drop the URL into the field above. There is no sign-up, no extension to install and no limit on how many stores you can check.
- 3
Read the detected theme
The tool fetches the store front end, scans the source for theme identifiers, and returns the theme name. If it cannot match a known theme it will tell you the store is likely running something custom rather than guess.
- 4
Copy the result
Use the copy button to save the theme name straight into your research doc, proposal or audit.
How the theme detector actually works
Every Shopify storefront ships with fingerprints of the theme powering it. When you request a page, Shopify renders a Shopify.theme object into the HTML containing the theme name and ID, and the asset URLs it loads follow predictable paths on Shopify's CDN.
The detector fetches that public HTML and reads those markers back. You could do the same by hand — open the page source and search for Shopify.theme — but the tool skips the digging and handles the cases where the identifier sits somewhere less obvious.
Nothing here touches the store's admin, and no account access is involved. It is the same public request your browser makes when you visit the shop.
Who uses a Shopify theme detector
Knowing what a store is built on changes what you quote, what you build, and what you benchmark against.
Ecommerce competitor research
Check what the best-performing stores in your niche are actually built on before you commit to a theme yourself. If three of your top competitors run the same theme, that tells you something about what converts in your category — and what your store will be measured against.
Development and design agencies
Before you quote on a build, you need to know what you are inheriting. Identifying the base theme tells you whether you are customising a well-documented commercial theme, extending one of Shopify’s free themes, or untangling a bespoke build with no upgrade path.
Freelancers scoping a project
A theme name is the fastest way to sanity-check a brief. "Make it look like this" is much easier to price once you know whether the reference store is running a $0 theme with heavy customisation or a $400 premium one out of the box.
Store owners planning a redesign
If you inherited a store and nobody documented the build, the theme name is the first thing a new developer will ask for. Finding it yourself saves a round trip.
Shopify themes this detector recognises
The detector matches against the themes you are most likely to meet in the wild — Shopify's own free themes and the best-known commercial ones. Anything it cannot match confidently is reported as custom.
Shopify's free themes
Dawn is Shopify's default reference theme and by far the most common result you'll see. If a store returns Dawn, assume the differences you're looking at are customisation rather than the theme itself.
Older free themes still in the wild
These predate Online Store 2.0. Finding one is a useful signal in an audit: the store likely hasn't had a serious front-end refresh in years, and section-based editing may not be available.
Popular commercial themes
Paid themes are the ones most often renamed during a build, so a store running one of these may still come back as custom.
What the detector can't tell you
Worth being straight about the limits, because they matter if you're quoting work off the back of a result.
- Renamed themes read as custom. Agencies rename themes when they fork them, which removes the identifier entirely.
- It does not report a reliable version number, so treat the result as the theme family rather than a specific release.
- It cannot see password-protected or unpublished stores, because the storefront has to be publicly reachable.
- It tells you the base theme, not how much has been changed on top of it — two stores on Dawn can look nothing alike.
- Apps are not themes. A lot of what looks like theme functionality is a third-party app, and that will not show up here.

Shopify theme detector FAQ
Paste the store URL into the detector above. It requests the store front end and scans the HTML for theme identifiers Shopify leaves behind — the Shopify.theme object, theme IDs, and asset file paths. Those clues usually name the theme outright. You can do the same manually by viewing the page source and searching for "Shopify.theme", but the tool does it in one step.
Yes. It is completely free, with no account, no sign-up and no cap on how many stores you can check. There is nothing to install either — it runs in the browser.
If the detector returns a theme, the store is on Shopify. Shopify stores also expose tell-tale paths like /cdn/shop/ or cdn.shopify.com in their source, and almost all of them respond at a .myshopify.com address. If a site is on WooCommerce, BigCommerce or a custom stack, this tool will not find a Shopify theme because there is not one to find.
Two common reasons. Either the store genuinely runs a bespoke theme built from scratch, which leaves no recognisable identifiers, or it runs a commercial theme that has been renamed and heavily modified during development. Agencies frequently rename a theme when they fork it, which removes exactly the clue a detector relies on.
It is reliable for standard and popular themes that have not been renamed. Accuracy drops when a theme has been heavily customised, forked and renamed, or built entirely in-house. It reports what it can verify from the source rather than guessing, so a "custom" result means no confident match was found — not that the tool failed.
It works on any publicly accessible Shopify storefront, using either the custom domain or the .myshopify.com address. It cannot read password-protected stores, stores still in development, or stores that are not live, because the front end has to be reachable for there to be anything to analyse.
Not reliably. Shopify does not consistently expose a theme version in the storefront source, and many stores run older versions long after an update ships. Treat the result as the theme family rather than a precise release number.
No. The detector makes an ordinary public request to the storefront, the same as any visitor loading the page in a browser. Nothing is reported to the store owner and no account access is involved anywhere in the process.
You can buy and install the same theme, and that is a perfectly normal thing to do. What you cannot do is copy a competitor’s customised code, custom graphics or copywriting — a theme licence covers the theme, not another company’s bespoke work on top of it.
No. The theme detector is open to anyone. A Partner account only matters if you go on to request collaborator access to a client store, which is a separate process you can read about in our Shopify access guide.
