TagGuard

Know exactly which Shopify apps still use script tags — before Shopify pulls the plug.

Shopify is deprecating script tags.

2026-10-01 — scriptTagCreate fails. Apps still shipping script tags can no longer be installed on new stores.
2027-03-01 — script tags stop running on every storefront. Anything not migrated dies silently.

Source: official changelog. Merchants get no built-in audit view — that's what TagGuard is for.

Audit your store in 30 seconds (free, open source)

npx scripttag-audit login                 # one-time OAuth
npx scripttag-audit scan --store my-store.myshopify.com

Lists every script tag, classifies it (affected / already dead / unknown), guesses the vendor behind it, and tells you the migration path (web pixel vs app embed). Exit code 1 while affected tags remain — CI-gate friendly.

What you get

Full inventory of the store's script tags with display scope and install dates.
Vendor attribution for 85+ common hosts (analytics, chat, popups, reviews, SMS…).
Per-tag migration plan — including skeleton code and ready-to-send vendor inquiry emails.
CI gate — fail builds while affected tags remain, re-run until green.
