Catalog Sentry Run audit

Free to see the drift. $49 to watch it.

The public audit reads what your storefront already serves. Catalog monitoring is the Shopify app that compares that against what Google and Meta actually hold - billed inside Shopify, 14-day trial, $49/mo.

Public catalogue audit
$0 no install
  • Paste a Shopify domain. We read /products.json plus one product page.
  • Missing types, images, thin copy, SKU-less variants, published-but-out-of-stock, missing Product schema.
  • No login, no cookie, nothing stored. Agents can call the same scan at /api/audit.
Run the free audit

A snapshot cannot see Merchant Center disapprovals or ID rewrites under live ads. That is the paid half.

Catalog monitoring
$49 /month
  • Shopify Billing, 14-day trial. No Polar, no Lemon Squeezy, no extra card form.
  • Coverage: products the store publishes that the channel is not holding.
  • Change: offer IDs rewritten under live campaigns, silent sync stalls.
Open the Shopify app Email me when listing is live

The App Store listing is not public yet (apps.shopify.com/catalog-sentry is 404). Installs go through the app host while that listing is in review.

What you are not buying

There is no $99 one-off report and no $19/mo waitlist SKU on this page. Those were a draft that never shipped. The chargeable plan that exists in the app is Catalog monitoring at $49/mo.

Connecting Google Merchant Center and Meta still needs a human signup. The free audit and the Billing trial do not.

Questions before you install.

The same answers sit in the page JSON-LD, so a crawler and a merchant read the same thing.

How do I install Catalog monitoring?

Open the app host at app.catalogsentry.com and install through Shopify. Billing is inside Shopify: 14-day trial, then $49/mo. The public App Store listing is still in review, so the app host is the install path until that listing is live.

Do I need to install anything for the free audit?

No. Every Shopify store serves its catalogue publicly at /products.json. We read only what your storefront already gives to anyone who asks, plus one product page to check its structured data. Nothing is connected and nothing is stored.

What does the trial cost, and how do I cancel?

The trial is $0 for 14 days. After that Shopify Billing charges $49 every 30 days. There is no Polar, Lemon Squeezy, or extra card form. Cancel from Shopify admin the same way as any other app.

What is the difference between this and a Shopify feed app?

Feed apps build and submit your product feed, and they are good at it. They look at one snapshot. They cannot tell you that your product IDs were rewritten yesterday, that your catalogue silently stopped syncing, or that your product pages are invisible to AI shopping assistants.

What Shopify access does the app need?

read_products and read_publications, so it can compare what you publish. Connecting Google Merchant Center and Meta still needs a human signup. The free audit and the Billing trial do not.

Start the 14-day trial.

Catalog monitoring is $49/mo after, billed inside Shopify. Cancel from Shopify admin. The public listing is still in review; install from the app host meanwhile.
