Shopify Theme Detector

TL;DR: This free Shopify theme detector identifies the exact theme any Shopify store is running, including the developer, price, and whether the merchant renamed it. It also detects 40+ installed apps. No browser extension needed. Paste a URL, get results in seconds.

How to tell what Shopify theme a website is using

There are three ways to detect a Shopify theme. The manual method involves opening DevTools, viewing the page source, and searching for Shopify.theme in the JavaScript. The extension method installs a Chrome extension like Wappalyzer or Koala Inspector. Both work, but both require effort every single time.

This Shopify theme detector automates the entire process. Enter a store URL, and the tool fetches two public Shopify endpoints: the /meta.json API (which confirms it's a Shopify store and returns store metadata) and the homepage HTML (which contains the Shopify.theme JavaScript object with the theme's unique store ID).

The tool then matches that store ID against a database of 300+ known themes and scans the page source for signatures of popular Shopify apps. You get a complete technology profile in one click.

How to use this Shopify theme detector

Enter a Shopify store URL in the input field above. You can type just the domain (like allbirds.com) or a full URL. The tool handles both.
Click "Detect Theme." The tool fetches the store's public metadata and homepage, extracts the theme information, and scans for installed apps.
Review the results. You'll see the theme name, developer, price, and category (free, paid, ThemeForest, or custom). If the merchant renamed the theme, both the display name and original name are shown.
Check store details. The store card shows the shop name, domain, myshopify domain, country, currency, product count, and accepted payment methods.
Browse detected apps. The apps section lists every app and integration detected from the store's page source, from analytics (Google Analytics, Meta Pixel) to reviews (Judge.me, Yotpo) to email marketing (Klaviyo, Omnisend).

Understanding Shopify theme categories

Free themes

Shopify maintains 14 free themes built by their in-house team. Dawn (ID 887) has been the default since Online Store 2.0. Other popular free options include Horizon, Sense, Craft, Origin, and Trade. These themes are fast, well-maintained, and sufficient for most stores. When this tool detects a free theme, it shows a green badge.

Paid Shopify Theme Store themes

The Shopify Theme Store lists 1,100+ paid themes from $100 to $420. Popular developers include Archetype Themes (Impulse, Motion, Expanse), Maestrooo (Prestige, Focal, Warehouse), Clean Canvas (Impact, Symmetry), Troop Themes (Broadcast, Streamline), and Out of the Sandbox (Turbo, Flex). Premium themes offer more sections, advanced filtering, and deeper customization than free themes.

ThemeForest themes

Themes sold through Envato's ThemeForest use IDs in the 99990000+ range. Minimog, Ella, and Kalles are among the most common. Some ThemeForest themes report a null theme_store_id, which makes them appear as custom themes. The tool's database includes the most popular ThemeForest themes.

Custom themes (null ID)

When theme_store_id is null, the store runs a custom-built theme not installed from any theme marketplace. This is common with Shopify Plus stores that commission bespoke designs. The Shopify theme detector will identify these as "Custom Theme" and still show all available store metadata and detected apps.

What is a Shopify theme store ID?

Every theme in the official Shopify Theme Store has a unique numeric identifier called the theme_store_id. Dawn is always 887. Impact is always 1190. Impulse is always 857. This ID is the same across every store that installs the theme.

This is different from the id field in Shopify.theme, which is a per-installation identifier unique to each store. If two stores both run Dawn, they share theme_store_id: 887 but have different id values.

The theme store ID is the most reliable way to identify a theme because merchants can rename themes in the Shopify admin. A store might display "Summer-2026-Final" as the theme name, but the theme_store_id still correctly identifies it as Dawn.

Why detect a competitor's Shopify theme?

Save research time. Instead of browsing hundreds of themes in the Shopify Theme Store, find what already works for successful stores in your niche and start from a proven design.
Budget accurately. Knowing whether a competitor uses a free theme or a $400 premium one helps you plan your own store setup costs.
Benchmark your tech stack. The Shopify app detector reveals what review apps, email tools, analytics, and payment options competitors use. That's a shortcut to building your own conversion stack.
Make informed redesign decisions. If your store's conversion rate is lagging, checking what themes top competitors use gives you data-backed options for your next redesign.

Limitations of this Shopify theme detector

Shopify only. Stores on WooCommerce, Magento, BigCommerce, or other platforms will return a "not a Shopify store" result.
Custom themes show limited info. When the theme_store_id is null (custom-built themes), the tool can't identify the theme name or developer. It still returns store metadata and detected apps.
App detection is pattern-based. Apps that load entirely server-side or use heavily obfuscated scripts may not be detected. The tool covers 40+ popular apps but not every app in the Shopify ecosystem.
Password-protected stores. Stores behind a Shopify password page block access to both the HTML and the /meta.json endpoint. The store must be publicly accessible.

Frequently Asked Questions

What Shopify theme is this store using?

Paste the store URL into this Shopify theme detector and click "Detect Theme." The tool identifies the theme name, developer, price, and whether it was renamed. Results appear in seconds, no browser extension required.

How do I detect what Shopify theme a store is using?

The fastest way is this tool. Enter a URL and the Shopify theme detector fetches the store's Shopify.theme JavaScript object and /meta.json endpoint, then matches the theme_store_id against a database of 300+ known themes. You can also check manually by viewing page source and searching for Shopify.theme.

Is this Shopify theme detector free?

Yes. Completely free with no usage limits, no account registration, and no browser extension required. Just paste a URL and detect.

Can I also detect Shopify apps on a store?

Yes. This tool doubles as a Shopify app detector. It scans the store's page source for signatures of 40+ popular apps including Klaviyo, Judge.me, Google Analytics, Meta Pixel, Yotpo, PageFly, Rebuy, and more. Detected apps are listed below the theme results.

How to tell what Shopify theme a website is using without a tool?

Open the store in your browser, right-click, select "View Page Source", and search for Shopify.theme. You'll see a JSON object like {"name":"Dawn","id":139441422,"theme_store_id":887,"role":"main"}. The theme_store_id (887 in this example) identifies the theme. Then look up that ID in a theme directory to find the theme name.

What does it mean when the theme store ID is null?

A null theme_store_id means the store uses a custom-built theme that was not installed from the Shopify Theme Store or ThemeForest. This is common with Shopify Plus stores that commission fully custom designs. The detector identifies these as "Custom Theme."

What Shopify theme does Allbirds use?

Try detecting it yourself! Paste allbirds.com into this Shopify theme detector to see their current theme, store details, and installed apps. Many large Shopify stores (Allbirds, Gymshark, ColourPop) use custom themes or heavily customized versions of premium themes.

Does this tool work as a Wappalyzer or BuiltWith alternative?

For Shopify stores specifically, yes. This tool provides deeper Shopify-specific analysis than general-purpose technology detectors: theme store IDs, rename detection, Shopify metadata, and payment method information. For non-Shopify websites, use Wappalyzer or BuiltWith instead.
