DealRaider - One search across second-hand marketplaces in Europe
by•
You check one marketplace, the seller is on another. DealRaider searches the second-hand sites it covers for your country and returns one list, sorted by price. Set an alert and it keeps watching — you hear about a new listing the moment it appears, even at 3am.

Hi Product Hunt 👋
I built this because I bought a used phone on the Dutch marketplace everyone uses, and found the same model two weeks later on another site for eighty euros less. It had been listed four days before I bought mine. Not hidden, not in some obscure corner — one site over, in my own language. I'd just stopped looking.
DealRaider doesn't stop looking. You give it a product and a price range, it searches the marketplaces it covers for your country, and comes back with one list sorted by price. Set an alert and it keeps watching in the background.
Some things that were harder than expected:
Every country writes prices differently. "1.299,00" here, "1,299.00" there, "170000 Ft" in Hungary with no separator at all. I lost a week to a bug where Hungarian prices were being read as zero.
Every language has its own word for "phone case", and short words hide inside longer ones — "capa" sits inside the Romanian word for storage capacity, so for a while every phone with its capacity listed was being thrown out as an accessory.
Sites break silently. They change their HTML and the scraper returns zero instead of an error. So there's a check that runs every night across every source and tells me which ones stopped working, before a customer notices.
It's a paid service, with day and week passes so you can try it for the length of one hunt. Honest about the limits too: a few marketplaces block bots outright and I can't reach those.
Happy to answer anything, and I'd like to hear where it falls short.
