Shopify Theme Detector — What Shopify Theme Is That?

What Is a Shopify Theme Detector?

A Shopify theme detector is a free tool that tells you which theme any Shopify store is running. You paste the store's URL, it reads the store's public code, and about five seconds later you have the theme's name, whether it is free or paid, what it costs, and a link to buy it.

That last part is the whole point. Knowing a name is trivia. Knowing whether you can install the same thing this afternoon, or whether it was built from scratch for one company, is a decision, and it is usually worth a few thousand dollars either way.

People use it for three jobs, in roughly this order: working out what the competition paid for, sanity-checking a theme before buying it, and finding out whether the store they have been trying to copy for two weeks was ever copyable.

We built this one at PageFly, where we work on Shopify conversion for 230,000+ merchants. It checks against a database of 10,000+ themes, which covers the entire Shopify Theme Store, 1,260 listings as of 10 September 2026, and thousands of third-party and private designs on top of that.

Why Theme Choice Impacts Your Conversion Rate

Your Shopify theme is not just a design decision — it directly affects your conversion rate, add-to-cart rate, and revenue per visitor. Theme detection helps you understand what top-performing stores use and why their theme choices drive sales. If you're still building your store, picking the right Shopify website builder matters just as much as the theme you choose.

"We couldn't display our products in our online store without PageFly. It has contributed to our growth tremendously. The homepage we built became the most visited part of our store."

— Toshi Sekiya, Founder of Syosaku-Japan (kitchenware brand that doubled its conversion rate after rebuilding key pages on top of its Shopify theme)

Here is where the theme, not your copy, decides the outcome:

Why this makes detection useful: every item above is decided by the theme, before you write a line of copy. So when you find a store that converts the way you want, knowing its theme tells you which of those decisions you can copy for $0, which cost a theme license, and which need a developer.

How to Find What Theme a Shopify Store Is Using

Using PageFly's Shopify theme detector takes less than 30 seconds. Follow these three steps:

Step 1: Copy the Store URL

Navigate to the Shopify store you want to analyze. Copy the full URL from your browser's address bar.

Either of these works:

• Root domain: allbirds.com
• Full URL: https://www.gymshark.com/collections/all

Step 2: Paste and Detect

Paste it into the box at the top of this page and click Detect theme.

The tool reads the store's front-end code, pulls out the theme fingerprint, and checks it against a database of 10,000+ themes covering the whole Shopify Theme Store plus thousands of third-party designs.

Step 3: View Your Results

Within seconds, the detector reveals the theme, whether it is official or custom, its price, and a link to the listing. Here is a real result — we ran asceno.com through the detector on this page on 10 September 2026:

Step 3 — a real detection run on asceno.com, tested first-hand by PageFly on 10 Sep 2026. The $400 and the 91% / 864 reviews match the Shopify Theme Store listing exactly.

What each field means:

What Your Shopify Theme Detection Results Mean

Every detection lands on one of three answers. They are not degrees of the same thing. Each one puts a different price on copying what you just looked at, so read which one you got before you plan anything.

Result 1: Official Shopify Theme

The store is running the theme as sold, with no code changes the detector can see. This is the easy result: whatever you liked, you can have.

You get the exact theme name, a link to its listing, and the price. Free, or somewhere between $100 and $500 one-off for a paid theme.

Result 2: Customized Official Theme

Someone bought a theme, then had a developer go into the code. The detector still names the base theme, and the base is the part you can buy. Everything on top of it was paid for separately.

What usually got added:

• Sections the theme editor does not offer
• Page layouts and navigation built from scratch
• Mega menus, custom filters, animation
• Type and styling past what the settings allow

The useful thing to notice: most of what reads as "custom" on a product page is layout and section order, not engineering. That part you can do yourself.

👉 See how PageFly works if you want to build sections on top of any theme.

Result 3: Fully Custom-Built Theme

The design was made for that one store. It is not in the Theme Store, not on a marketplace, and not for sale at any price.

A real custom-theme result: allbirds.com, run on 10 Sep 2026. Tested first-hand by PageFly.

Who ends up here: large retailers, and stores that need something the platform does not do.

A custom result is not a dead end, it just moves the question. You cannot buy the theme, but you can rebuild the two or three layouts you actually admired — an AI page builder will read a screenshot of a page and lay out its structure for you, which is a different job from cloning a theme and a much smaller one.

What they have in common is developers on staff, or a budget that rents them.

Hybrid is what most stores should pick, and not as a consolation prize. The pages that decide a sale are the product page and the landing page, and those are the two you can rebuild without touching the theme.

If you want to see what that looks like before committing to anything, the PageFly template library is the fastest way to judge it: pick a layout close to the store you were trying to copy, and you will know within a few minutes whether the gap was really the theme.

If you would rather build from nothing than adapt something, read up on vibe coding for Shopify first.

👉 Run the numbers on a custom build before you fall in love with one.

Shopify Theme Examples – See the Detector in Action

Wondering what themes successful Shopify stores actually use? We ran three top-performing stores through PageFly's Shopify theme detector to show you real results, and explain why each theme choice drives conversions for that brand.

Examples re-verified first-hand on 10 September 2026 — we re-ran each store through the detector and cross-checked the raw Shopify.theme object in its page source. The values below are what those stores returned that day.

Example 1: Allbirds — Sustainable Footwear

Allbirds sells shoes made of wool and eucalyptus, and the store is built to get out of the way of that story. The design does almost nothing, on purpose.

What that buys them:

• Layouts with one thing to look at, so the eye goes to the shoe and then to the button
• Materials copy sitting inside the product page rather than parked on an About page nobody opens
• A nav with barely anything in it, which works because they sell a dozen shoes, not a thousand
• Pages that load fast, which is the only sustainability claim a shopper can actually feel

Steal this if you have a short product line and something real to say about it. You do not need a bespoke build to get here. Dawn and Craft are both free and both start from the same place: white space and a big photo.

Example 2: Gymshark — Fitness & Athletic Apparel

Gymshark has the opposite problem to Allbirds: a very large catalog and an audience that arrives from Instagram, on a phone, already half sold. The store is built to move that person to a size and a color quickly.

What that buys them:

• Loud, high-contrast imagery that survives being seen for two seconds
• Filtering that holds up past a thousand products, which is where most themes quietly give up
• Athlete sections built into the theme, so social proof is a layout, not a plugin
• A phone-first build, because that is where the traffic lands

Steal this if you sell a lot of variants to people arriving from social. Filtering is the feature to shop for, and you can buy it: Impulse at $500 and Symmetry at $420 both ship with it.

Filtering only works on a catalog that is organized underneath, which is a separate job. Our guide to the Shopify catalog covers that part.

Example 3: Asceno — Luxury Sleepwear & Resort Wear

Asceno is the useful one of the three, because it is the one you can copy.

Asceno positions itself as a luxury lifestyle brand, not just a sleepwear company. Its silk pyjamas, linen pieces and swimwear command premium prices, and the Prestige theme's editorial layout carries that positioning without custom development.

What Prestige gives them:

• Editorial-style layouts give the brand room to build the confidence a $200–$500 purchase needs
• Large-format imagery slots let silk texture and craftsmanship do the selling
• Generous whitespace and restrained typography match the price point
• Minimal navigation suits a curated, deliberately small catalog
• Native lookbook sections blend resort and loungewear ranges in one browse path

What you can learn: a luxury brand does not need a custom theme. Asceno runs a $400 off-the-shelf theme — the same one anyone can buy today, and that is the most useful thing detection can tell you. The interesting part is that its theme is named [ASCENO 2024] Prestige, not "Prestige". More on why that matters below.

What These Examples Reveal

The pattern: two of the three run custom themes, and that is exactly why you should check before you copy. Spend three weeks trying to recreate the Allbirds homepage on a free theme and you are fighting a bespoke build. Asceno is the opposite lesson: the look you admire is on sale for $400. Detection is what tells you which of those two situations you are in, in about five seconds. For the bespoke ones, the practical route is a solid base theme plus a page builder for the sections that matter, rather than a ground-up rebuild.

Shopify Theme ID, Theme Name and schema_name: How to Read What a Detector Tells You

This is the part almost nothing on the internet explains, and it is where most theme research goes wrong. The theme name a Shopify store publishes is a free-text field the merchant can type anything into. The theme's real identity lives in two other fields next to it. Learn to read those two and you will never again spend an afternoon hunting for a theme that was never for sale.

Every public Shopify storefront exposes a small object called Shopify.theme in its page source. Here is a real one, copied from asceno.com on 10 September 2026:

Shopify.theme = { "name": "[ASCENO 2024] Prestige", "id": 126836244598, "schema_name": "Prestige", "schema_version": "9.3.0", "theme_store_id": 855, "role": "main"}

What each field actually means

The one-field test: can I buy this theme?

Read theme_store_id and stop. Here are the four stores we checked on 10 September 2026:

Notice that not one of the four 名称 values would have found the right theme in a search box, and two of the four would have sent you looking for a theme that does not exist. That is the single most common failure in theme research, and one field fixes it.

How to turn a theme_store_id into a theme you can actually open

Plenty of people search for a way to look a theme up by its ID. There isn't a URL for it — we tested this. themes.shopify.com/themes/855 returns a 404, even though 855 is genuinely Prestige's Theme Store ID. Theme Store URLs are built from the theme's slug, not its number:

1. Read schema_name from the page source — that is the theme's real name.
2. Go to themes.shopify.com/themes/ plus that name in lowercase. プレステージ → themes.shopify.com/themes/prestige.
3. Confirm you have the right listing: the Theme Store page carries the same ID in its own markup (data-monorail-click-tracking-theme-id-value="855"), so if that number matches the theme_store_id you read, it is the same theme.
4. Read the live price off that page before you budget. Prices move — three of the themes in our own table above had changed since Q1.

Step 4 — the Prestige listing on 10 Sep 2026: $400 USD, 91%, by Maestrooo. Screenshot taken first-hand by PageFly; this is the page that settles a price argument.

One number that is not a theme ID

Shopify serves theme assets from paths that look like this:

/cdn/shop/t/450/assets/custom-fields.css

について 450 in there is tempting, and it is not a theme ID. It is a counter for how many themes that particular store has had installed. Asceno's assets sit under /cdn/shop/t/450/; PageFly's demo store, running a completely different theme, sits under /cdn/shop/t/48/. Two different themes, two different numbers, and neither number means anything outside its own store. If you have been trying to look up a theme by that digit, that is why nothing came back.

Why Shopify Merchants Use Theme Detection

Nobody runs a theme detector out of idle curiosity for long. The four uses below are the ones that actually change a decision, and each one turns a guess into something you can check.

1. Competitor Research and Market Intelligence

Detect a rival's theme and you learn more than what they like the look of. You learn what they were willing to spend, and where they decided the money mattered. A store on a $400 theme with a heavily reworked product page has told you exactly where it thinks its conversions come from.

Run 10 to 20 competitors before you pick your own theme. Patterns show up fast. If the strongest stores in your niche keep landing on the same theme, that theme probably solves something you have not hit yet. If nobody uses the one you are eyeing, you have either found an edge or you are about to learn why everyone else passed.

The whole sweep takes an afternoon. It settles a decision you would otherwise make on taste.

2. Competitive Analysis with Actionable Context

Gallery posts and "best Shopify stores" lists show you the finish line. They almost never tell you how far away it is.

Here is how that guessing usually goes wrong. You find a store that converts, study the layout, and spend three weeks rebuilding it, only to find out it was a $50,000 custom job. Or you buy the theme, launch it, and realize the store you copied had a developer rework half of it.

Detection settles it in about five seconds. What you are looking at is one of three things:

• A theme you can buy today
• A bought theme plus developer work
• A bespoke build that was never for sale

Now your research is a plan instead of a mood board.

Pattern-matching is where it pays. Save five to ten stores you would trade places with, run each one, and look at what repeats:

3. Theme Evaluation Before Purchase

A Theme Store demo is a showroom. Everything in it was picked to flatter the theme: the photos are the right shape, the copy is the right length, the catalog is small and tidy. Your store is none of those things.

So before you spend $100 to $500, find three to five real stores running the theme and check:

• Photography: does it survive images that look like yours?
• Scale: does filtering still work at your catalog size?
• Range: how differently can two stores wear the same theme?
• Phone: open it on yours and try to buy something

Skip that step and the theme price turns out to be the cheap part. You lose the weeks spent fighting a layout that cannot do what you need, and you pay again when you move.

4. Clearer Communication When Hiring Developers

Developers quote what they can picture. A vague brief gets a padded quote, because padding is the only defense against "something like this store."

Detection hands you the vocabulary that fixes it:

You will not get a percentage out of this. You will get a shorter conversation, and a brief that names a theme and a section is a brief someone can actually price:

• Quotes that hold, because the scope was written down
• Fewer rounds spent agreeing on what "clean" means
• A shared vocabulary for what counts as working

→ Skim the best Shopify themes guide first, so you can name a base theme instead of describing a mood.

Quick Reference: When to Use Theme Detection

Most Popular Shopify Themes in 2026 — Original Data

Two things are worth separating here, because most articles blur them. The first is what our own tool sees: 47,382 theme detections run through PageFly's Shopify theme detector. The second is what the whole platform looks like, measured by a third party that crawls every live store. They do not agree, and the gap itself is informative.

Read the dates: the PageFly detection sample below is a Q1 2026 snapshot (January–March 2026) and has not been re-sampled since. The independent platform-wide figures further down were read on 10 September 2026. Where the two disagree, trust the September figures for "what is common today" and the Q1 sample only for "what people were looking up".

Top 9 Shopify Themes by Detection Volume

Share column = PageFly detection sample, Q1 2026. Price column = Shopify Theme Store list price, re-checked 10 September 2026 (three of them had moved since Q1: Impulse $380→$500, Prestige $380→$400, Symmetry $380→$420 — a reminder to check the live listing before you budget). Remaining ~44%: legacy free themes no longer sold (Debut, Brooklyn — still detected on older stores), other themes, and custom builds.

A note on legacy themes: Earlier free themes like Debut and Brooklyn still appear on many established stores, but Shopify has retired them from the Theme Store — new merchants can no longer install them, so they're left out of the ranking above. If your detector returns "Debut" or "Brooklyn," that store is running an older Online Store 1.0 theme that Shopify now replaces with Dawn or Horizon for new stores.

What the whole platform looks like (independent, read 10 Sep 2026)

Store Leads crawls live Shopify stores rather than sampling a tool's users, and it tracks over 4,000 distinct theme names. Its State of Shopify 2026 report, read on 10 September 2026, ranks them like this:

The row worth staring at is the first one. The most-detected theme name on Shopify is trademark, and there is no trademark theme for sale: themes.shopify.com/themes/trademark returns a 404 (we checked on 10 September 2026). That is the whole lesson of this article in one line — a detected theme name is not a shopping list. Before you go hunting for a theme a detector named, check whether it is a listing you can actually buy.

Two other takeaways from that table: Dawn and Horizon are the two most-used themes you can actually install, and both are free. And Debut is still on ~117,000 live stores even though Shopify stopped selling it, so a "Debut" result tells you the store is old, not that you can copy it.

Key Findings

Free Themes Dominate the Market

52% of the stores in our Q1 2026 sample ran free themes. (Sample figure, not a platform census — see the independent table above for the platform-wide picture.)

Despite 1,236 paid listings in the Theme Store (Sept 2026), most merchants stay on a free theme. In our Q1 sample Dawn accounted for nearly a quarter of detections; platform-wide in September it sits at 9.1%, still the most-used buyable theme. Horizon — Shopify's newer default free theme — has climbed to 5.7% of all live stores, which makes it the fastest-moving theme in the ecosystem. Our Shopify Horizon theme review looks at what is driving that.

The Shopify Theme Store's own price filter, 10 Sep 2026: 24 free, 1,236 paid. Screenshot taken first-hand by PageFly — this is where the counts in this article come from.

Four reasons it keeps happening:

• New merchants prioritize cash flow over upfront design costs
• Dawn's Online Store 2.0 architecture handles most customization needs
• CRO platforms like PageFly enable conversion-optimized layouts without theme upgrades
• Shopify's investment in free theme quality has closed the gap with premium options

What you actually give up: free themes are not worse-looking, they are narrower. The things paid themes tend to add are structural — multi-facet collection filtering, sticky add-to-cart, quick-view, mega menus, more section types. If your catalog is small and your pages are simple, a free theme costs you nothing. If shoppers need to filter 500 SKUs, that is the wall you hit first.

The Paid-Theme Power Law

The paid end of the market is far more concentrated than the free end. In our Q1 sample, Impulse and Prestige together took about 47% of all paid-theme detections — two themes, half the money.

They win on the same four things, and they are worth using as a shopping list when you compare any paid theme:

• Filtering that survives a large catalog
• A homepage you can rearrange without a developer
• Mobile performance that holds up
• A publisher who still ships updates

They are not the only good ones. Sunrise ($240, by Rawsterne) sits at 93% positive on the Theme Store and suits brighter, product-led brands.

→ Compare the paid Shopify themes side by side.

Custom Themes: Who Actually Uses Them?

18% of the stores in our Q1 sample ran a custom build. The interesting part is who they were.

Custom themes are what stores buy after they work, not what makes them work. At $10,000 to $50,000+, the spend only makes sense once you already know what your customers respond to. Reading it backwards, and building bespoke to get there, is the expensive mistake this whole page is meant to help you avoid.

Trend Watch: What's Changing in 2026

Set the Q1 sample against what came before it and a few things are clearly moving:

What we will be watching (and you can check us): Horizon passed Savor into third place platform-wide by September 2026. If Shopify keeps it as the default for new stores, the number to watch is whether Horizon overtakes Dawn — Dawn 9.1% vs Horizon 5.7% on 10 September 2026, both from Store Leads. Debut's ~117,000 remaining stores are the other clock: that number only goes down.

How We Collected This Data

How the Q1 2026 sample was built:

• Sample size: 47,382 unique Shopify store URLs
• Collection period: January–March 2026
• Source: Anonymized scans through PageFly's Shopify theme detector
• Categorization: Themes matched against Shopify Theme Store database + custom theme fingerprinting
• Exclusions: Duplicate URLs, non-Shopify stores, password-protected stores

Three things it cannot tell you:

• Data reflects stores scanned through our tool, which may skew toward merchants actively researching themes
• Custom theme detection groups heavily modified official themes with fully bespoke builds
• Historical comparisons use consistent methodology but sample composition varies quarter-to-quarter

Updates: the PageFly detection sample above is a Q1 2026 snapshot and has not been re-sampled since — we have labelled it that way rather than leave a stale date implying otherwise. The independent platform-wide table is re-read when we update this page; it was last read on 10 September 2026. Bookmark the page and check those two dates before you quote a number from it.

Why Shopify Theme Detection Might Not Work

Most stores give up their theme without a fight. Five situations do not, and they fail for different reasons, so the fix is different each time. Work down the list.

Issue 1: The Store Isn't Built on Shopify

The detector only analyzes Shopify stores. Sites on other platforms return no result.

None of these are Shopify, so there is no Shopify theme to find:

• WooCommerce (WordPress)
• ビッグコマース
• Magento / Adobe Commerce
• Wix or Squarespace eCommerce
• Custom-built platforms

Four ways to settle it, weakest first:

If the store isn't on Shopify, similar platform-specific detectors exist for WooCommerce and other platforms.

Issue 2: The Store Is Password-Protected

A locked store shows one page: a password form. The theme code you want lives on the homepage, product pages and collection pages, and none of those load until someone lets you in. Stores sit like this before launch, during a rebuild, or when they are members-only.

You can tell in a second. There is a "Enter store using password" prompt, no products anywhere, and the URL resolves but never gets past that one form.

Issue 3: Headless Commerce Setup

Some stores keep Shopify for orders, inventory and checkout, but build the shopfront themselves in React or Next.js. There is no Liquid theme in the picture, so there is nothing for a detector to name. It is not a failed detection; the thing you are looking for does not exist.

The usual frameworks are Hydrogen (Shopify's own React framework), Next.js Commerce, Remix, and Vue Storefront.

You can usually spot one before you even check the source: pages swap instantly with no reload, the URL sometimes does not change when you click, the source is full of React instead of Liquid, and there are no cdn.shopify.com asset paths.

New in 2026, and relevant if you are studying headless stores: Shopify's Storefront MCP lets AI shopping agents such as ChatGPT and Perplexity browse and buy from a headless storefront directly. Being invisible to a theme detector no longer means being invisible to shoppers. Our guide to Shopify AI agents covers what that changes.

Either way, a headless store is bespoke by definition. Study the layout decisions, but price the work as development, not as a theme purchase.

Issue 4: Heavily Modified Theme Code

Occasionally a developer takes an official theme and rewrites so much of it that the fingerprint is gone. Not customization in the normal sense: most template files replaced, standard asset names changed or deleted, whole components rebuilt.

The detector will call it custom, and for your purposes it is right. Even if you dug out the original base theme, it would not help you. Nothing you can see on that store came from it.

Issue 5: Technical Blocks

Sometimes the store is fine and the request is the problem.

Alternative Detection Methods (re-tested September 2026)

When automated detection fails, these are the manual fallbacks. We re-ran every one of them on real stores on 10 September 2026 before publishing this list, because manual methods rot quietly — one of the four that used to be recommended everywhere, including in an earlier version of this article, no longer works at all. Each method below is marked with what we actually observed.

Method 1: View Page Source — ✅ still the best manual method

Works on any publicly reachable Shopify store, and it is the only method that gives you theme_store_id.

Five steps, about thirty seconds:

1. Open the store in your browser
2. Right-click → "View Page Source" (or press Ctrl+U / Cmd+U)
3. Press Ctrl+F / Cmd+F to search inside the source
4. Search for Shopify.theme
5. Read schema_name (the real theme) and theme_store_id (whether you can buy it) — not 名称, which the merchant can type anything into

A real result, read from asceno.com on 10 Sep 2026:

Shopify.theme = {"name":"[ASCENO 2024] Prestige","id":126836244598, "schema_name":"Prestige","schema_version":"9.3.0", "theme_store_id":855,"role":"main"}

Once you have the schema_name, searching it in the Shopify Theme Store is the last step — here is that search on 10 Sep 2026:

Step 5 — searching the Theme Store for the schema_name you just read. Screenshot taken first-hand by PageFly, 10 Sep 2026.

Faster variant: instead of reading source, open the browser console (F12 → Console), type Shopify.theme and press Enter. You get the same object, already formatted. It works on any Shopify storefront and takes about three seconds.

Verified on allbirds.com, gymshark.com, asceno.com and beariestore.com — all four exposed the object. See the field-by-field breakdown in the section above.

Method 2: Check Theme Asset Paths — ⚠️ works, but not the way most guides describe

Older guides (this article included, until this update) told you to look for a file called theme.css?v=dawn-1.0. We could not find that pattern on a single store we tested. Modern Shopify serves theme assets from a path shaped like this instead:

/cdn/shop/t/450/assets/custom-fields.css/cdn/shop/t/48/assets/cart-drawer.min.js

One keystroke, then read the address bar:

1. Open Developer Tools (F12 or right-click → "Inspect")
2. Go to the Network tab and refresh the page
3. Filter by CSS または JS and look for paths containing /cdn/shop/t/
4. Read the filenames, not the number — asset filenames are a theme fingerprint (Prestige ships custom-fields-widgets.js; the Label theme ships .min.js variants)

Do not read the number as a theme ID. について 450 そして 48 above are per-store install counters, not theme identifiers. Method 1 is strictly better if the page source is available; use this one when you want to see which theme files a store has customized.

Method 3: The /admin redirect — ✅ new, and the fastest platform check

This one takes one keystroke and answers two questions at once: is this Shopify, and what is the store's real handle?

Do it in this order:

1. Type the store's domain followed by /admin in your address bar
2. Watch where it lands. A Shopify store redirects to <handle>.myshopify.com/admin and then to a login screen
3. Read the handle out of that URL — that is the store's internal Shopify name
4. Stop there. You do not sign in, and you could not if you tried; the redirect is the whole signal

Verified 10 Sep 2026: asceno.com/admin → 301 → asceno-london.myshopify.com/admin. allbirds.com/admin → 301 → weareallbirds.myshopify.com/admin. A non-Shopify site gives you a 404, its own login page, or nothing.

This is also the method to reach for when the "Powered by Shopify" footer text has been removed, which on larger brands it almost always has.

Method 4: Ask, or look for the credit — ✅ still works

In rough order of how likely they are to work:

• Contact the store owner and ask (many are happy to share)
• Check the store's blog or About page — some list their stack
• Look for agency credits in the footer ("Built by …")
• Search the store's name plus "Shopify theme" to find case studies or build write-ups

❌ Retired: inspecting the checkout page

Every guide to this topic, including earlier versions of this page — told you that Shopify's checkout kept theme references, so you could add a product to the cart, go to checkout, and read the theme from there. That method is dead, and it is worth knowing why so you stop trying it.

Shopify has been retiring checkout.liquid, the theme file the checkout used to run on. Per Shopify's own developer documentation, checkout.liquid is unsupported for the Information, Shipping and Payment steps; the Thank you and Order status pages sunset on 28 August 2025 for Shopify Plus stores, with script tags following on 26 August 2026 for everyone else. The checkout now renders from Checkout Extensibility, not from your theme.

We confirmed it end to end on 10 September 2026: we added a product to a cart on a live Shopify store, followed it to the real checkout URL (/checkouts/cn/…), and searched the resulting page. Zero occurrences of Shopify.theme, theme_store_id, schema_name, or any /cdn/shop/t/ asset path. There is nothing left there to read.

If you have a bookmarked workflow that ends at the checkout page, replace that step with Method 1 or Method 3 above.

Quick Troubleshooting Checklist

Still Can't Detect a Theme?

Three things left to try, in order:

1. Read the source yourself. Method 1 above works on plenty of stores the detector cannot reach.
2. Give up on the name and copy the thinking. Screenshot where the CTA sits, what the trust signals are, how the page is stacked, then find a theme that starts closer to it in our best Shopify themes guide.
3. Send it to us. Email happytohelp@pagefly.io with the URL and we will look at it ourselves.

Shopify Theme Checker, Theme Finder & "What Theme Is This?" — One Tool, Many Names

Three different searches, one job. A Shopify theme checker, a Shopify theme finder, and typing "what Shopify theme is this?" all mean the same thing: hand over a store URL, get back the theme it runs. The detector at the top of this page does all three, so whichever wording you used, you are in the right place.

Is this a Shopify theme checker?

Yes. Checking means confirming whether a store runs a real Theme Store theme or a custom build, and which one. Paste the URL, wait about five seconds, read the answer. Nothing to install and nothing to log into.

Use it as a Shopify theme finder

Finding is the harder half, and it is where a bare theme name lets you down. The detector returns the theme, whether it is free or paid, what it costs right now, and a link to its listing, so you can go and get the same one instead of starting another search.

"What Shopify theme is this?" How to answer it in 5 seconds

You do not need to read code. Copy the store's URL, paste it into the box at the top of this page, read the result. If the store is locked or headless and nothing comes back, Method 1 further down does the same job by hand.

Shopify Theme Detection: PageFly vs. Manual Methods

There are three ways to identify what theme a Shopify store uses. Here's how they compare, and why most merchants choose automated detection.

Quick Comparison

They are not really competing. The detector answers the question fastest, the page source answers it most precisely, and an extension answers a different question: what else is running on that store.

Method 1: PageFly's Automated Theme Detector

The detector fetches the store's front end, pulls the theme fingerprint out of the HTML and asset paths, and matches it against a database of 10,000+ themes. Then it does the part that saves you the real time: it looks up whether that theme is on sale, what it costs today, and where to buy it.

That last step is why the output is more useful than a name. A name sends you to Google. A name plus theme_store_id plus a live price tells you whether to open your wallet or your budget spreadsheet.

It comes up empty on password-protected stores, headless builds, and anything sitting behind aggressive bot protection. For those, drop to Method 2.

Method 2: Manual Source Code Inspection

Slower, but it is the ground truth. You are reading the store's own declaration of what it runs, so there is no database to be out of date.

Here is a real object, read from beariestore.com on 10 Sep 2026:

Shopify.theme = {"name":"Bearie Store eCommerce eBooks and News", "schema_name":"Label","schema_version":"3.6.0", "theme_store_id":773,"role":"main"}

The theme is Label. It is not "Bearie Store eCommerce eBooks and News". That is the store's nickname for it.

What you gain over the detector: the version number and the asset structure, which tell you how current and how modified the build is. What you give up: two to five minutes per store, a tolerance for scrolling through minified HTML, and any help finding the listing afterwards. It also comes up blank on the same locked and headless stores, so it is a sharper tool, not a stronger one.

Worth learning anyway. Once you have read three of these you will understand how Shopify themes are put together, which makes every later conversation with a developer shorter. If minified source is new to you, start here.

Method 3: Browser Extensions

An extension sits in your toolbar and reads every page you visit, so you never type a URL anywhere. Wappalyzer, BuiltWith and a handful of Shopify-specific add-ons all work this way.

What is actually on the Chrome Web Store — we searched it on 10 September 2026, because listings in this category get renamed and delisted often:

If you want a store's apps as well as its theme, an extension is the right tool — that is the one job extensions do that this page's detector does not. The detector above answers the theme question; the two "Inspector" extensions above also list installed apps and pixels.

What they are good at:

And what you pay for that:

Where extensions get it wrong, and why: the failure is structural, not sloppiness. An extension reports a theme by matching what it reads against a bundled list of theme names. Two things break that:

• Renamed themes. An extension that surfaces the 名称 field reports "[ASCENO 2024] Prestige" or "[DNAM Theme July 2026]" — technically what the store published, useless as an answer. Only schema_name gives the real theme.
• List lag. A theme released after the extension's last update is not in its list, so a brand-new theme comes back as "unknown" or "custom" even when it is a $400 listing you could buy today.

Both are the same reason source-code reading (Method 1) beats every extension when accuracy matters: schema_name そして theme_store_id come from the store itself, so there is no list to be out of date.

Best for: Users who want passive detection while browsing multiple stores, or need broader technology stack information beyond just themes.

Which One Should You Actually Use?

Start with the detector. It is faster, it needs nothing installed, and it hands you the price and the link, which is the part you were going to look up next anyway. Keep the page source for the cases the detector cannot reach, and for when you need to be certain rather than fast.

The gap only really shows up at volume. One store either way is a wash. Twenty stores is the difference between an afternoon and a coffee break, and a proper competitive sweep is fifty.

結論

Use the detector first; keep Method 1 in your back pocket.

The detector at the top of this page gives you, in about five seconds and with nothing to install: the theme, whether it is official or custom, its current price, and a link to the listing. That covers the everyday question.

Reading Shopify.theme yourself (Method 1) is the one thing worth learning on top, for three situations the detector cannot cover for you:

• The store is password-protected or geo-blocked from where the detector runs, but loads for you
• You want schema_version to see how old a store's theme release is
• You want to prove a theme is unbuyable before quoting a client — theme_store_id: null is the receipt

Everything after that is a research question, not a detection question: which theme suits your catalog, and what you can change without buying a new one.
