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

Install TagGuard on the Shopify App Store → — free, read-only, scans your script tags and theme files from the admin.

Prefer the terminal? The open-source CLI does the same audit locally:

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

Reads your live storefront HTML (the surface that sees tags injected by other apps), plus your theme's liquid files, and classifies each script — affected, already dead, theme-embedded, or app embed. It maps the vendor and the migration path (web pixel vs app embed); exit code 1 while affected tags remain — CI-gate friendly. Password-protected and bot-protected storefronts may need a manual check.

What you get

Storefront + theme inventory — app-injected tags from the live HTML, hard-coded theme scripts, and per-theme app embed switches (ON/OFF).
Vendor attribution for 86 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.
