If you sell payments, delivery or software to online shops, the platform a shop runs on is a useful place to start. Shopify and Magento shops have different needs, different budgets and different partners. A list built around the right platform saves your team from calling the wrong businesses.
This UK guide shows how many UK online shops use each platform, how to check a single website for free, and 3 ways to build a full list, from free search tricks to list tools and B2B data.
Key takeaways
- TAMI AI counts 114,447 UK online shops on Shopify and 8,757 on Magento, out of 423,906 with an add-to-cart and online payments (November 2026).
- You can check a single site for free. Shopify sites load files from cdn.shopify.com, and Magento sites set cookies that start with "mage-".
- Free search tricks find some shops but miss most. List tools and B2B data tools find them at scale.
- The most useful lists combine the platform with other filters, such as payment provider, shipping carrier and country, and include the right contacts.
- Before you email, check the list is current and follow the UK rules on emailing businesses.

Magento's count is much smaller than Shopify's, which makes a Magento list short enough to work through account by account.
How to tell if a website uses Shopify
You can check one site in under a minute, for free:
- Look at the page source. Right-click the page and choose "View page source", then search for
cdn.shopify.com. Shopify shops load their images and files from that address. - Check the footer. Some shops still show "Powered by Shopify". Many remove it, so a missing line doesn't rule Shopify out.
- Try the products page. Adding
/products.jsonto a shop's address often shows its product list as data. This isn't an official Shopify feature, and some shops block it, so treat it as a quick hint rather than proof.
How to tell if a website uses Magento or Adobe Commerce
Magento (Adobe Commerce is the paid version) sets its own cookies when you visit a shop. Open your browser's developer tools (F12 in Chrome), go to Application, then Cookies, and look for names such as mage-cache-storage, mage-messages or X-Magento-Vary. These are on Adobe's own list of default storefront cookies, so their presence is a strong sign the shop runs Magento.
Method 1: Free search tricks
For a small list, a search engine can help:
site:myshopify.complus a product word, such assite:myshopify.com candles, finds shops still using their original Shopify address."Powered by Shopify"plus a product word finds shops that kept the footer line.
These tricks are free, but they have limits. Most established shops use their own web address and remove the footer, so you'll miss far more than you find. There's no reliable equivalent trick for Magento. You'll also need to check every result by hand and find the contacts yourself.
Method 2: Technology list tools
Technology list tools scan millions of websites and let you download every site using a platform. The main options, with their lowest public prices on 13 November 2026:
| Tool | What you get | Starting price |
|---|---|---|
| BuiltWith | Lists of sites by technology, with contact names and export | $295 a month (2 technologies) |
| Store Leads | Ecommerce store lists by platform, with filters | $75 a month (Premium; 2 platforms) |
| Wappalyzer | Lead lists by technology, plus single-site lookups | $250 a month (Pro) |
| Datablist | Company lists by technology, credit-based | $25 a month (Starter, 5,000 credits, per its own guide) |
All prices are in US dollars, from each vendor's own website. As a worked example, a list covering both Shopify and Magento fits within the 2-platform limit of Store Leads Premium ($75 a month) or BuiltWith Basic ($295 a month). On Datablist's Starter plan, 5,000 credits at 5 credits per website covers about 1,000 websites a month.
These tools are good at finding websites. What they show next to each site varies: some give contacts, some give traffic, and most count websites rather than companies, so 1 business with 3 shops can appear 3 times.
Method 3: B2B data with platform, payments, carrier and contacts
If your goal is a list your sales team can work, a B2B data tool can combine the platform with the other facts that decide whether a shop is a good fit. In TAMI AI, for example:
- Choose the platform: Shopify, Magento or both.
- Narrow the market: United Kingdom, add-to-cart, online payments, and a size range.
- Add a fit filter: the payment provider at checkout (see our count of UK online shops by payment provider), or the shipping carrier they use today (see our logistics lead generation guide).
- Add the people: the head of ecommerce, operations or payments, with verified contact details.
For example, a payments company might look for UK Shopify shops that don't yet offer a "buy now, pay later" option. A 3PL might look for the 8,757 UK Magento shops, then keep only those that ship to several countries. For more on finding shops by what they use, see our guide to finding ecommerce merchants. To check one shop at a time, our Chrome extension shows its platform, payments and carriers in 1 click.
Shopify vs Shopify Plus, and Magento vs Adobe Commerce
Shopify Plus is Shopify's plan for larger businesses. From the outside, most Plus shops look like any other Shopify shop, so most tools, ours included, can only reliably tag a small number as Plus. The rest are counted as Shopify. If Plus matters to you, use size filters such as online turnover alongside the platform.
Magento comes in 2 main forms today: Magento Open Source and Adobe Commerce (the paid version). Shops still on the old Magento 1 are running software that no longer gets updates: Adobe's security bulletin of 22 June 2020 said support for Magento 1 was ending that month, with the final security patches. Shops still on Magento 1 may be looking for a new platform, and new partners with it.
Before you email the list
2 checks before your first email:
- Is the list current? Shops change platforms, close and move. A list from 6 months ago will contain shops that have moved on. Re-check before you send, or use data that updates.
- Are you following the UK rules? The ICO's guidance on business-to-business marketing says the PECR consent rule for marketing emails doesn't apply to corporate subscribers, such as limited companies. You must say who you are and give a valid way to opt out. Sole traders and some partnerships are treated like individuals, so they generally need to have given consent. A named person's business email is still personal data under UK GDPR. The ICO notes its guidance is under review after the Data (Use and Access) Act.

Frequently asked questions
How do I know if a website uses Shopify?
View the page source and search for "cdn.shopify.com". Shopify shops load their files from that address. A "Powered by Shopify" line in the footer is another sign, but many shops remove it.
How can I get a list of Shopify websites?
For a few shops, search "site:myshopify.com" plus a product word. For a full list, use a technology list tool such as BuiltWith, Store Leads, Wappalyzer or Datablist, or a B2B data tool such as TAMI AI that adds contacts and other filters.
How do I find Shopify Plus stores?
It's hard, because most Plus shops look like ordinary Shopify shops from the outside. The most practical way is to filter Shopify shops by size, such as online turnover, to focus on the larger businesses most likely to be on Plus.
How do I tell if a site runs Magento or Adobe Commerce?
Open your browser's developer tools and check the site's cookies. Names such as "mage-cache-storage" or "X-Magento-Vary" appear on Adobe's own list of Magento cookies.
Are there free ways to find Shopify stores?
Yes, for small lists: search operators such as "site:myshopify.com" and "Powered by Shopify", and checking the page source of a single site. They miss most established shops, so paid tools are needed for a full list.
How do I find the contact details for a store?
Technology list tools vary in the contacts they include. B2B data tools add named decision makers, such as the head of ecommerce, with verified email addresses and phone numbers.
Final thoughts
Shopify runs on about 1 in 4 UK online shops and Magento on about 1 in 50. Free checks will tell you what a single site uses. Platform data is one kind of technographic data. For a list your team can work, combine the platform with the payment providers, carriers and countries that make a shop a good fit, and add the right people.
