Everything ThemeSweep finds and fixes

A scanner built specifically for the dead-code Shopify apps leave behind. No false positives. No theme rewrites. Just a clean, fast theme.

Detection

• Per-app dead-code signaturesWe maintain a database of code patterns left by 200+ Shopify apps. When you uninstall an app, we know exactly what stub liquid blocks, snippets, and asset references it leaves behind.
• Asset auditFind CSS and JS files imported by uninstalled apps. Estimate the byte savings before you remove anything.
• Liquid block scannerFind <!-- BEGIN: app-name --> markers, theme.liquid header injects, and dead-template includes left behind by app uninstalls.
• Metafield orphansFind product/customer metafields written by apps that are no longer installed. Clean them up to reduce schema drift.

Speed impact

• Lighthouse before/afterWe run a Lighthouse audit before you clean up and again after, so you see the exact speed improvement.
• Asset weight trackerHow much KB you saved by removing each dead block. Cumulative weight of all theme cleanup wins.
• Mobile vs. desktop splitSpeed gains are biggest on slow mobile networks. We show you both.

Safety

• One-click theme backupBefore any cleanup, we duplicate your live theme. If anything looks off, restore in one click.
• Staging-theme cleanupYou can preview every change against an unpublished theme. No risk to your live store.
• Reversible cleanupsEvery removal is logged. Restore individual blocks or whole-theme rollbacks any time.
• Read-only by defaultThe first scan is purely diagnostic. Cleanups require explicit consent per block.
