DealSonar watches Facebook Marketplace and Vinted for you and pings you the moment a profitable listing appears. Set a monitor once (keyword, price range, condition, location radius) and DealSonar does the rest: AI filters out junk and wrong models, eBay sold comps show what the item actually sells for, and a profit calculator does fees and postage before you message the seller. Alerts via email, Discord, or Telegram.
I flip secondhand gear. The whole game is speed: the good listings on Facebook Marketplace and Vinted are gone in minutes, and the only way to catch them was refreshing the same searches all day on my phone.
So I built DealSonar. You set a monitor once, what you're hunting, your price range, condition, how far you'll travel and it watches both marketplaces for you. When something lands, you get a ping with the three things you actually need to make the call:
• What it sold for on eBay recently (real sold comps, not asking prices) • Your profit after fees and postage • Whether it's the real thing or noise AI filters out wrong models, parts-only listings, and scams
Alerts go to email, Discord, or Telegram, so you get them wherever you already are.
I'd genuinely love to hear what you'd want it to monitor and if you flip things yourself, what your current process looks like. Happy to answer anything in the comments today.
