CatalogSentry — Interactive Demo

Watch it check that your feed agrees with itself.

Most feed validators check that a field exists and is the right type. CatalogSentry checks something else: does the title's "256GB" match the description's "128GB"? Do two SKUs sharing a GTIN know they're duplicates? Does a "variant" actually differ from its sibling?

This page is not a mockup. The products below are from a real, unmodified 995-product public e-commerce catalog (a Flipkart sample dataset) — not the repo's 5-product demo fixture — run through all 15 checks, every one enabled. Every finding you'll see below is quoted verbatim from that real run, not written for this page.

CatalogSentry is an early-stage tool, validated once end-to-end against this real 995-product public catalog — not yet against a real customer's own feed. It's live and callable on Apify Store today. This demo shows exactly what it does today, nothing more.
