Theme Drift: Compare & Diff
Subtitle
Compare two or three themes to catch conflicts.
Introduction
Compare two or three theme versions at once. See what changed, and whether it's yours or new.
Details
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.
