[ Universal Retailer · Free ]

Lights up on 50,000+ stores. Stays out of the way otherwise.

The retailer content script matches every URL outside Amazon. It probes our combined_pool database on each page — when it recognises a product, the panel auto-activates with the cheapest version of the same product across every store we sweep. When it doesn't, it stays completely silent. No clutter on pages it can't help with.

  • Matches https://*/* in the manifest — runs on every site
  • Probes pricelyzer.app on page load + SPA navigation to identify
  • Activates only when the URL is a known product page (no clutter)
  • Walmart, Target, Home Depot, Costco, CVS, BAM + 50K long tail
  • Same chrome as the Amazon panel — buy box, profit, gating, sources

[ Amazon · Product surface · Pro ]

A full sourcing panel on every product page.

With Pro mode on Amazon PDPs, a floating tab slides out with everything you'd otherwise tab over to a calculator for — buy box, net profit, exact fees, gating verdict, retailer-side arbitrage matches, and 30-day price + BSR history.

  • Live buy box + 30-day price & BSR history pulled per visit
  • Net profit + ROI computed against your account's fees
  • Live SP-API gating verdict, per condition (Pro only)
  • Retailer arbitrage matches scored from our 50K-store database
  • One click to fold into a Bulk Sourcing run or open in the cockpit

  • Scratch Category — current page + next 2 pages of pagination
  • Results stream into a bottom drawer as each ASIN clears
  • 2.2s inter-call delay respects Amazon's SP-API rate budget
