Compare two or three theme versions at once. See what changed, and whether it's yours or new.
Theme Drift lets you compare two or three Shopify themes at once. With three, compare the original theme, your customized live theme, and a new theme version side by side. When a theme you've customized gets an update, it's hard to tell which changes are your own edits and which are new from the developer. This app shows all versions together, and flags any file where you and the new version changed the same thing, so you can bring your customizations forward safely.
