App Stack Doctor

Find leftover app code, render-blocking scripts and overlapping apps, with the exact line to fix.

Uninstalled apps often leave code in your theme that keeps slowing every page, and it is easy to end up paying for two apps that do the same job. App Stack Doctor scans your theme and storefront in under a minute and gives you a 0-100 health score with a prioritised list of issues: leftover code from removed apps, scripts that block your page from rendering, apps pasted into your theme, switched-off apps you may still be paying for, and overlapping apps.

• Finds leftover code from uninstalled apps, down to the file and line
• Flags render-blocking app scripts and heavy apps by size
• Spots overlapping apps and estimates what you could save
• Read-only: never edits your theme or adds code to your store
• Health score and history so you can track improvements
