Shopify leftover app code checker
Uninstalling a Shopify app does not always remove every theme reference. Leftover code can slow pages, break UX, and confuse future edits.

App experiments often leave hidden theme debt.
- Old snippets and includes still referenced by theme files.
- Script tags, app embeds, or settings left active after uninstall.
- Theme comments and blocks that make future debugging harder.
Check before deleting anything from a theme.
- Duplicate the theme and search for app names, handles, domains, and snippet references.
- Review app embeds, custom liquid blocks, theme settings, and script references.
- Remove only confirmed dead references, then re-scan and test key journeys.
FAQ
Why does app code remain after uninstall?
Some apps add theme snippets, settings, or merchant-managed code that Shopify cannot safely remove automatically.
Can I just delete anything with an old app name?
No. Confirm the reference is unused first, because some stores keep shared scripts, pixels, or custom features tied to app names.
