Keepa
Amazon price and sales-rank history tracker used by shoppers and sellers to monitor long-run price and demand trends.
Keepa tracks and charts the history of Amazon listings: price over time (including Buy Box price by seller), and Amazon's Best Sellers Rank (BSR), which it uses as a public proxy for relative product demand rather than actual unit sales. It is available as a free browser extension that overlays price-history graphs directly on Amazon product pages, plus a web dashboard for tracking lists of products and setting price-drop alerts. Sellers use its longer historical charts and public API to gauge how a product's price and rank have moved over months or years, which is useful for competitive research and deal validation, though — like other tools built on public marketplace signals — its demand read-outs are estimates inferred from rank movement, not confirmed sales counts.
