About the App Stack Doctor
App Stack Doctor scans your Shopify theme and storefront in under a minute to find leftover app code that slows down every page. Get a 0-100 health score with a prioritized list of issues including code from uninstalled apps, render-blocking scripts, and overlapping apps that waste your money.
The app identifies leftover code down to the exact file and line, flags render-blocking app scripts and heavy apps by size, and spots overlapping apps while estimating potential savings. It also detects apps pasted into your theme and switched-off apps you may still be paying for.
Completely read-only, App Stack Doctor never edits your theme or adds code to your store. Track your store's improvements over time with health score history and fix issues that impact your site speed and budget.
