What we track

Three signals that matter.

PRICE-DROP ALERTS

Never miss a markdown

The moment a competitor drops a SKU price — even by a dollar — you get an email and Slack ping with the old price, new price, and a direct link to the product.

NEW-PRODUCT DETECTION

Be first to know

ShelfLens crawls competitor Shopify catalogs daily. When a rival adds a new SKU — a new flavor, a new form factor, a new category — you know before any press release.

AD-CREATIVE TRACKING

See what's working for them

We reverse-engineer competitor Facebook pixels to surface every new ad creative they test. Know when they pivot messaging, launch a promotion, or double down on a winning angle.
