Every app you uninstall leaves code behind, including scripts, styles, snippets, SEO tags, tracking pixels, orphaned metafields, and more. These still load in your theme long after the app is gone. Left unchecked, orphaned code slows your store, hurts SEO, and can interfere with how customers experience your site. Ghost Code recognizes 100+ apps by signature and tells you exactly which app left each fragment, in which file, at which line.
