Passportify

Digital Product Passports for Shopify — ESPR compliance, SHA-256 integrity, and a public mobile-first passport page.

Install Passportify from the Shopify App Store or your Shopify Admin. We never ask for your shop domain on this page.

Product compliance catalog. Create and edit DPP drafts linked to your Shopify products.
Cryptographic seal. SHA-256 field contract + Merkle anchor for anti-greenwashing trust.
Public passport page. Mobile-first /p/:passportId with QR for customers and auditors.

For local development, open the app from Shopify Admin via shopify app dev → press P (Preview), not the bare tunnel URL.
