HYPEIBIZA checks the stock and prices of more than 60 sneaker and streetwear shops and publishes one page per product with the shops that carry it, their price, the sizes in stock and a 90-day price history. Free app for iPhone and Android with barcode scan and price-drop or restock alerts, a Chrome extension, a blog widget and an MCP server. English and Spanish. It sells nothing itself; some links pay a commission.
