Sweeprice tracks competitor prices on 14 marketplaces (Amazon, Cdiscount, Fnac, ManoMano, Darty, eBay, Leroy Merlin, Boulanger, BUT, Conforama, La Redoute, Back Market, Etsy, Decathlon) and recommends a price for each of your listings.

You add a product by link, reference or barcode, or import a CSV, XML or Google Shopping feed. The same product is matched across marketplaces, so you see every competing offer, who holds the Buy Box and the price history in one place. You get an alert when a competitor drops its price, when you lose the Buy Box or when you leave the top 3.

Each rule has a floor price. The recommended price stays between that floor and your usual price. You can apply it yourself or let the rule run. If there is no direct competitor, Sweeprice can test the price in steps, or compare your listing with a substitute product you choose.

Connecting your seller account is optional. A Claude connector (MCP) lets you query your prices from Claude.
