Every week, thousands of sales reps, agency owners, app developers, and growth hackers face the same question:
“Is this store actually built on Shopify?”
With headless builds, custom storefronts, and Shopify Plus customization at an all-time high, the answer isn’t always obvious.
So we manually tested every major Shopify detector in late 2025 across the same list of:
- 100 real stores
- 20 countries
- From Taylor Swift’s merch to micro Korean DTC brands
We measured:
- ⚡ Speed
- 🎯 Accuracy
- 💰 Free-tier usefulness
- 🧩 Theme/app detection
- 🌐 API quality
- 🔧 Real-world usefulness (sales, outbound, audits)
Here are the only 9 tools worth using in 2025.
