Find the code uninstalled apps left behind in your Shopify theme.
Free public scan. No signup. Paste your store URL and see what's still loading.
How it works
Paste your store URL
Any Shopify storefront — your .myshopify.com address or your custom domain.
We scan the public pages
We fetch your homepage and check every script, comment, and CSS class against our database of known Shopify app code patterns.
See what's loading
You'll see which apps are loading code on your store, grouped by app, with confidence ratings. If you don't use those apps anymore, that's residue dragging your store down.
Common questions
What's "leftover code"?
When you uninstall a Shopify app, Shopify revokes the app's access instantly — which means the app can't remove the code it injected into your theme. That code keeps loading on every page forever, slowing your store down and adding nothing.
Is this safe? Do you change anything on my store?
The public scanner doesn't touch your store at all. We just fetch the same HTML any visitor sees and check it against our database. We don't need any login or permission.
Why doesn't this find everything?
Public storefront HTML only shows what's currently being rendered. The really painful residue is often in theme files (snippet files, asset files, sections) that you can only see if you have full theme access. That's what the Shopify app version does.
Why is this free?
Because surfacing the problem is most of the battle. Once you can see what's loading on your store, you'll know whether you need to act. If you do, the Shopify app is $9/month to clean it up automatically.
