As answered by people managing Diffee and DealSonar.
DealSonar's answer:
Choose DealSonar if you want speed and clarity together: continuous monitors across the marketplaces resellers actually use, instant alerts (Dashboard, Email, Discord, Telegram), and sold comps with profit estimates instead of alerts alone. It is built as a web dashboard for UK, US, and EU resellers, with a 7-day free trial on paid plans.
DealSonar's answer:
Resellers, flippers, and side hustlers who source on Facebook Marketplace, Vinted, eBay, and OfferUp, then sell on eBay or other channels. Typical users hunt phones, laptops, consoles, trainers, and other high-turn categories across the UK, US, and EU
DealSonar's answer:
DealSonar combines multi-marketplace monitoring with deal judgment in one workflow. You get alerts for Facebook Marketplace, Vinted, eBay, and OfferUp, plus eBay sold comps and profit estimates on matching listings, so you can decide whether to buy before you message the seller.
DealSonar's answer:
DealSonar started from the same problem most local resellers hit: good deals disappear while you manually refresh Marketplace. The product was built to watch searches continuously, alert the moment a listing matches, and surface comps and margin so you can act in seconds, not after the item is gone.
DealSonar's answer:
Next.js / React (web app) Supabase (auth and data) Stripe (billing) Optional Chrome extension for messaging workflows
