Shopify Theme Detector
Paste a Shopify store URL and read the theme straight off the storefront: its name, its version label, and whether it is a Theme Store theme or a custom build. Every result opens as a full store profile, so you also see what the store running that theme actually does in numbers. Free to start, no signup needed for your first checks.
What theme is this Shopify store using?
A real scan of aventon.com. Every check opens the same way: as a store profile with the theme next to the apps, traffic and revenue.

Free theme, paid theme, or custom build?
A Shopify theme detector reads the theme metadata a storefront exposes publicly and returns the theme name, plus whether it is a Shopify Theme Store theme or a custom build.
Every Shopify storefront declares its active theme in the pages it serves. Paste a store URL and the detector reads that declaration once, then reports the theme name, the version label when the store exposes one, and whether the theme is listed on the Shopify Theme Store or built specifically for that merchant. The example above is real: aventon.com reports Release, 07-30-26, a custom build carrying the merchant's own release label.
That distinction is the useful part, because it prices the look you are studying. An official free theme means the design is reachable for nothing. A paid Theme Store theme means the same foundation typically costs $180 to $400. A custom build means the storefront you admire sits on an agency budget, and no theme purchase will reproduce it. Store owners use this to shortlist themes, and agencies use it to scope a redesign before quoting.
The detector is equally direct about what it cannot read. Headless storefronts and aggressively stripped builds expose no theme layer, and in those cases the result says so instead of guessing. A store can be confirmed as Shopify and still have no readable theme, and that is an answer, not a failure.
What the theme detector tool shows you
Theme name and version
The name comes straight from the theme metadata the storefront serves, together with a version or release label when the store exposes one. No guessing from screenshots, no pattern matching on layout.
Theme Store theme or custom build
Every result is flagged one way or the other. The flag is the difference between a look you can buy for a few hundred dollars and a look that was commissioned for that one merchant.
What the same look would cost you
Official free themes cost nothing. Paid Theme Store themes typically run $180 to $400, and you can look any detected name up on the Theme Store for current pricing and a demo. Custom means hiring, not buying.
Headless stores, called out honestly
Storefronts built on Hydrogen or other custom frontends have no readable theme layer. The detector confirms the store is Shopify and says the theme is not readable, instead of inventing a name.
How do I find out what theme a Shopify store uses?
Paste the store URL
A bare domain or a full product link both work, the input is normalized either way. We first confirm the site is actually a Shopify store, and that confirmation is free.
We scan the storefront
One fetch of the public storefront reads the theme declaration and the app fingerprints together. A fresh scan costs 1 credit. If the store was scanned recently you get the cached result, it costs nothing, and the page says so.
Read it on the store profile
You land directly on the theme block of that store's profile. The apps, traffic and revenue sections sit on the same page, so the follow-up questions are already answered.
Is the store behind that theme actually selling?
Check the revenue estimate first
A beautiful storefront is not evidence that a theme works. Before spending a few hundred dollars to copy one, open the modelled monthly revenue on the same profile. The 24 hour sales shape is free to preview, and the absolute numbers unlock for 2 credits.
See where its visitors come from
A store with a great look and no traffic is a showroom. The profile shows estimated monthly visits and the channel mix behind them, so you can tell a theme carried by real demand from one propped up by ad spend.
Read the catalogue and price band
The same profile lists how many products the store publishes and what they cost, for free. A theme holding up a four hundred product catalogue at real prices proves more than any demo store.
Watch the store, not just the theme
If the store is worth copying it is worth revisiting. Add it to your watchlist and come back as the numbers refresh, instead of re-researching it from scratch next month.
Theme checker, theme finder, template detector
People reach this page calling it a Shopify theme checker, a Shopify theme finder, a template detector, or just by asking what Shopify theme a store is using. The names all describe the same lookup: paste the store URL, read the theme from the store's profile, and decide what to do with it.
Shopify Theme Detector FAQ
How detection works, and when it fails
The detector fetches the public storefront once, the same pages any visitor loads, and reads the theme declaration Shopify serves inside them. From that single read it reports the theme name, a version label when one is exposed, and whether the theme is a Theme Store listing or a custom build.
Yes. A custom theme is flagged as a custom build, and the name shown is whatever the merchant called it internally. The aventon.com sample on this page is exactly that case: the storefront reports Release, 07-30-26, the merchant's own release label.
Headless storefronts render outside the Liquid theme layer, so there is no theme name to read. The result confirms the site is Shopify and states that the theme is not readable. That is the honest answer, and it is itself useful: it tells you the store invested in a custom frontend.
Three common reasons: the store is headless, the storefront blocks automated reads, or the fetch failed mid scan. The result page tells you which case you hit. A blocked or failed read is worth retrying later, and a repeat within the cache window costs nothing.
Credits and cost
Free to start, honestly priced after that. Your first checks work without any signup. A signed in account gets 5 free credits every day, and a fresh theme scan costs 1 credit. There is no way to run up a bill by accident: every paid action shows its price before you click.
No. Scans are cached, and a repeat check inside the cache window is served free. The result page labels it, so you can tell a free cached read from a scan that spent a credit.
Not for your first checks. An account adds the daily free credits and a watchlist, which is what you want once you are tracking specific stores rather than running one lookup.
From theme name to buying decision
If the result says Theme Store theme, search the name on the Shopify Theme Store for current pricing, screenshots and a demo. Paid themes typically run $180 to $400, official free themes cost nothing. If the result says custom build, there is nothing to buy: that look was commissioned.
Not from the demo. The store profile behind every result shows the revenue estimate, the traffic and the catalogue of the store you found the theme on. A theme running under a store that measurably sells is evidence. A theme that merely looks good in a demo is marketing.
Partially. The custom flag and the version label are real signals, but detection cannot itemize how far a Theme Store theme was modified. Treat a detected paid theme as the foundation of the look, not a pixel for pixel guarantee.
Scope and privacy
No, and that is by design. This site only does Shopify. If you are not sure what a site runs on, the Shopify store detector answers the platform question first, for free, and tells you when a site is not Shopify at all.
No. Many themes share the same layouts, so visual similarity proves nothing. Detection needs the live store URL, because the answer comes from metadata the storefront serves, not from how it looks.
The scan reads pages that are public to any visitor, nothing more. There is no notification to the merchant and nothing for them to approve.
