Finding Out What Theme You Are Currently Running
You are staring at your store, trying to figure out if you are using Dawn, Horizon, Impulse, or some random custom template your previous agency slapped together three years ago. It happens all the time, especially when you inherit a site, buy an existing business, or built something in a massive rush and totally forgot what design you actually paid for. Figuring out what theme is running behind the scenes isnt just about satisfying your curiosity, it is actually pretty important if you want to install new apps, hire a developer, or upgrade your layout without breaking everything on your site.
The good news is that finding your theme name and version is simple. You can use our free tool, glance at your Shopify backend, or peek directly at the page code if you want to feel like a hacker for five minutes. Using a method like this, you will know what you are at moving forward and you can stop guessing every time you read an app installation guide that asks for your template name.
Option 1: The Super Quick Search Tool
If you dont want to log into your admin panel or click around menus, the fastest trick is using our shopify theme detector. We built this tool to save people time, and it is pretty handy, if we dont say so ourselves. All you need to do is copy your store homepage link, paste it into the search box, and hit check.
Our tool inspects the public files on your website, scans the underlying javascript variables, and tells you the exact theme name alongside whether it is an official theme from the store or a custom build. It takes about two seconds, which means you dont have to waste ten minutes looking through admin settings just to answer a simple question. It is particularly useful if you manage multiple storefronts or if you are looking at a competitor website and wondering what theme that is so you can steal their styling ideas for your own shop.
Option 2: Checking Inside Your Shopify Dashboard
If you already have your dashboard open in another tab, you can locate your template details right inside the settings menu. First off, head over to the left sidebar and click on Online Store, which automatically drops you onto the Themes tab. Right there at the top of the screen, you will see a card showing your Current Theme.
If you are using a default design from Shopify and nobody changed the label, the name will be listed right under the preview image. You will see something like Dawn or Spot or Publisher. However, developers love renaming theme files to things like Live Theme Final V2 or Site Backup Do Not Touch. If your developer renamed your theme, reading that card wont immediately help you work out the original foundation code.
To bypass custom titles, click the small three-dot menu icon next to the Customize button and select View details. If the theme was downloaded directly from the official Shopify Theme Store, this details page will reveal the original system title, the developer who built it, and usually a link to the original documentation. If that section is missing or blank, it means your store is running an unlisted design downloaded from a third party market or a bespoke code build written entirely from scratch.
Option 3: Inspecting Source Code Like a Developer
For anyone who likes seeing how things work in the background, you can find your design identity straight from your browser view. You dont need any special developer permissions or backend logins for this method, which means it works on any site on the internet.
Open your store in Chrome, Firefox, or Safari. Right click anywhere on the page canvas and hit Inspect or View Page Source. A giant wall of code will pop up on your screen. Dont panic, you don’t need to read any of it. Just press Ctrl and F on Windows, or Command and F on Mac, to open the page search bar, and type in Shopify.theme.
You will usually see a small block of javascript that looks like this:
Shopify.theme = {"name":"Dawn","id":12345678,"theme_store_id":888,"role":"main"};
The name key tells you the title of the layout, while the theme_store_id gives you a massive clue about where it came from. If there is an official store ID number attached, it is a verified theme from the official directory. If the ID says null or is missing entirely, it was uploaded via a zip file from an outside source or built by an agency.
Why Knowing Your Layout Version Actually Matters
Why bother checking this at all? Beyond general curiosity, your theme identity dictates almost everything about how your store functions on a technical level. Shopify rolled out a massive architecture update called Online Store 2.0 a while back, which completely changed how app blocks and page sections work. Older themes, often called Vintage themes, handle code completely differently than modern designs.
When you try to install popular modern apps for upsells, customer reviews, or custom fields, those apps need to know if you are on an OS 2.0 framework like Dawn or an older legacy system like Vintage Brooklyn or Supply. Installing modern app integrations onto an ageing, legacy theme can cause code bloat, slow down your loading times, or completely ruin your mobile shopping experience. Once you know your base template, you can easily read app setup docs and make sure everything is compatible before clicking install.
Knowing your theme version also helps immensely when you hit a bug and need technical support. If you contact an app support team or post on the community forums asking for help with a broken image gallery, the very first thing anyone will ask is what theme you are using. Knowing the precise name and parent version allows developers to spot known bugs quickly and give you a straight answer straight away.
What To Do If Your Theme Says Custom
Sometimes you run a lookup check or look in your admin area only to discover your active theme is labeled as Custom or Unknown. That isn’t necessarily a bad thing, but it does mean you have to treat website updates slightly differently than standard stores.
A custom label usually happens for two reasons. Either a freelance coder built a bespoke theme ground up for your brand, or an agency took a standard base layout like Impulse or Horizon and heavily edited the liquid code files directly inside the editor. When you edit core liquid code files, Shopify disconnects the file from auto-update systems to protect your code from being overwritten during updates.
If you find yourself running a heavily modified or custom layout, keep these tips in mind before making major site changes:
- Never hit the update button without creating a duplicate copy of your live store first so you have a quick backup if things break.
- Be cautious when installing apps that automatically edit theme code, because they might place snippets in outdated file paths that your custom theme doesn’t use anymore.
- Keep a document of all custom features your store relies on, such as custom drawer carts, mega menus, or custom page templates, so you don’t accidentally lose them if you switch layouts down the road.
Upgrading or Switching to a Fresh Look
Once you figure out what template you are on, you might realise it is severely outdated, missing built-in features, or just looking a bit old fashioned compared to modern brand stores. If your current theme is more than two years old, upgrading to a modern Online Store 2.0 layout is one of the best moves you can make for store speed and conversion rates.
Modern designs include rich sections on every single page, built-in filter options, native slide out carts, and faster image loading out of the box. That means you can usually delete half of your paid monthly apps because the core layout handles those functions natively now. If you decide it is time for a change, simply browse the theme directory, preview designs inside your admin panel without publishing them, and transfer your content over safely behind a dev preview window while your existing site stays live to customers.
Frequently Asked Questions
Can I check what theme another store is using?
Yes, you can easily check any public site by pasting their domain into our theme detector tool. The tool reads public script tags and stylesheet identifiers to display the theme name instantly without needing any back-end permissions.
Why does my Shopify admin just say Custom Theme?
Your theme will display as custom if a developer built it from scratch or heavily modified an existing layout’s source code. When core code structure is edited, Shopify stops tracking the original theme store identifier to avoid breaking custom functionality during automated updates.
How do I know if my layout is Online Store 2.0?
Go to your store editor under Online Store and click Customize. If you can add sections and blocks to any page layout including product and collection pages rather than just the homepage, you are running an Online Store 2.0 compatible theme.
