What it does

When you uninstall an app it often leaves code behind in your theme. ThemeSweep scans your active theme, finds that leftover code and shows which app it probably came from. You review the report first; nothing changes without your approval. Remove it on a duplicated theme with a full backup and one-click rollback, or comment it out instead.

  • Finds leftover JavaScript, CSS, Liquid and orphan files from uninstalled apps
  • Shows the evidence for each finding before anything changes
  • Cleans up on a duplicate theme, with a full backup first
  • Roll back to the pre-cleanup theme in one click
