How to Tell What Shopify Theme a Website Is Using: A Practical Guide for Busy Owners

Introduction
Want to know what Shopify theme a competitor or inspiration store is using — fast and without getting lost in code? This guide gives you practical, non-technical steps to identify a Shopify theme, spot custom work, and use the findings to improve your own store.
What you’ll learn: quick manual checks, the best automated tools, what the results mean, and what to do next so you can make smarter design and investment decisions.
The problem: why this matters
Choosing the right theme affects conversions, load speed, and how easy it is to add features. Yet many business owners either buy the wrong theme or assume a great-looking store must be fully custom. Knowing what theme a site uses helps you: - Benchmark layout and features. - Estimate development work needed to replicate a look. - Save money by choosing a theme that already supports essential features.
Quick, non-technical approach (the solution)
You don’t need to be a developer. Use this simple two-step approach: 1. Manual check with your browser. 2. Use a reliable theme detector to confirm.
Manual check (2–3 minutes) - Open the store in your browser. - Right-click and choose “View Page Source” (or press Ctrl/Cmd + U). - Use the page search (Ctrl/Cmd + F) and look for keywords: theme, Shopify.theme, or asset paths like /cdn/shop/t/. Why this works: many themes include their name or an internal ID in filenames or JavaScript variables. If you find Shopify.theme = { name: "Dawn", ... } — you’ve found it.
Automated detectors (fast and easy) - Try tools like What Store Theme or ShopThemeDetector, or ShopifyDevTools’ Theme Detector. Paste the store URL and read the results. - Use at least two detectors; cross-checking reduces errors.
What the results tell you (and what they don’t)
Detected info can include: - Theme name and developer (official or third-party). - Theme ID (useful to match in the Shopify Theme Store). - A “custom” label when an exact match isn’t found.
Limitations: - Custom or heavily modified themes may appear as “custom” or be misidentified. - Some merchants remove identifying comments or rename files to obscure the theme. - Automated tools aren’t foolproof — manual checks help validate.
Quick checklist to run right now
- [ ] Open the target store and view page source.
- [ ] Search for Shopify.theme, theme.css, or /cdn/shop/t/.
- [ ] Run the URL through 2 detectors and compare results.
- [ ] Look at visible features on the site (filters, mega-menu, product options) to match theme demos.
- [ ] Document your findings in a simple spreadsheet for later review.
Tips for a reliable read
- If detectors disagree, trust manual clues (asset filenames, Shopify.theme JS variable).
- Compare the target site to theme demos in the Shopify Theme Store — many official themes have live demos you can view.
- Remember: presence of a theme file doesn’t mean the look is unchanged — apps and custom CSS can alter appearance significantly.
Example: what to do if you see “custom”
If detectors return “custom”: 1. Check for brand-named CSS/JS files (these often indicate agency work). 2. Inspect the network tab (Developer Tools → Network) to see third-party scripts that could affect layout. 3. Decide if you want a fully custom build (more expensive, unique) or a standard theme plus customizations (cheaper, faster).
Ethics and next steps
Stick to public data only. Don’t attempt to access private areas or scrape large amounts of pages — that can violate terms of service and privacy expectations.
