    How it sells itself

    Native Shopify preview links expire in 48 hours and drop template context the moment a visitor navigates to another page. Advanced Theme Preview fixes both. Generate secure, long-lived preview links that work on your real storefront with live products, collections, and pages. No dev store needed.

    Finally understand what's happening with your store's theme code without being a developer. Compare any two themes instantly and see exactly what's different between them - highlighted in a way that makes sense even if you've never seen code before.

    Key points
    • Generate secure preview links that expire in up to 5 days
    • Browse live products, collections, and pages on draft themes without a dev store
    • Selected templates persist across all pages during a preview session
    • Revoke preview access instantly or let links expire automatically
    • Side-by-side comparison of any two themes
    • Line-by-line highlighting of all changes
    • File-by-file breakdown showing which templates were modified
    • Works instantly with all Shopify themes
