About CommerceWatch

CommerceWatch is a historical product observation platform: a continuously-refreshed record of retail product observations across the open commercial web. We track which products exist, where they appear across retailers, and how that presence changes over time.

The platform serves institutional buyers — financial and quantitative research firms, market-intelligence teams, e-commerce analytics vendors, and manufacturers — who need a reliable, provenance-linked view of retail reality rather than a consumer price-checker.

Coverage figures are published openly as a measure of scale and data quality. The underlying observations — prices, retailer-level detail, and full historical series — are provided to licensed subscribers. Request access.
