ThemeSweep

Finds & safely removes dead code left by uninstalled apps — with backup & one-click rollback.

When you uninstall an app, it often leaves code behind — orphaned snippets, dead scripts, unused CSS, and leftover Liquid buried in your theme, weighing down every page. ThemeSweep scans your active theme, finds that dead code, and attributes each finding to the app that left it. You review a clear report first — nothing changes without your approval. Then remove it in one click, on a duplicated theme with a full backup and one-click rollback, or quarantine it to comment code out instead.

• Automatic dead code detection — Scans your entire theme to find JavaScript, CSS, Liquid, and orphan files left behind by uninstalled apps
• Safe one-click cleanup — Creates a full theme backup before every cleanup. Choose remove or quarantine mode. Preview changes before publishing
• Instant rollback — Restore your theme to its pre-cleanup state with one click. All backups retained for 30 days
