Auto Theme Sync moves Liquid, JSON, CSS and JavaScript files between themes inside one Shopify store. Pick a source theme and one or more target themes, choose the files to sync, and review a colour-coded diff before anything is written. Per-file progress streams live and the app respects the Admin API rate limit so large theme syncs never hammer your store. Add scheduled sync, automatic backups and one-click rollback so a sync can be reverted from history.

• Diff preview for every file before syncing
• Multi-target sync — push the same change to every staging theme at once
• Sync history with one-click rollback
• Scheduled sync — hourly, daily, or weekly profiles
• Smart rate-limiting and automatic retry on transient API errors
