This guide shows you four free ways to detect Shopify apps on any store. Use these methods to spy on competitor stores and find what apps they use.

Why Find Out What Shopify Apps a Store Uses?

Here's why this matters for competitor research:

• Learn from winners - See what apps top Shopify stores use
• Find new tools - Discover apps you didn't know existed
• Understand strategy - App choices show what a store focuses on
• Save money - Check if successful stores use an app before you buy it
• Find gaps - See what competitors aren't using

The average Shopify store uses 6+ apps.
