About AMZBase - Free Amazon Product Research Tool

AMZBase is a free product research tool for Amazon sellers. It renders ranking, offer, listing and chart-link data directly on Amazon search, category and product detail pages, so research data is available without leaving the page. • No registration • No login • All settings stored locally • No collection of Amazon account information or browsing history Search and category page data cards — at-a-glance information, no need to open the product detail page. On Amazon search results, category pages and Best Sellers lists, AMZBase renders a data card under each product, displaying: • ASIN, with a one-click copy button • Best Sellers Rank, including the subcategory rank where applicable • Lowest Fulfilled-by-Amazon (FBA) offer price • FBA seller count • A "Sold by Amazon" indicator when Amazon itself is on the offer list • A green indicator when an FBA offer sits at least 30% above the lowest offer (a possible arbitrage signal) Data cards render automatically once the page loads.
