DealHunter
Multi-marketplace deal alerts across 7 resale platforms
Monitors all 7 marketplaces — Facebook Marketplace, eBay, OfferUp, Mercari, Craigslist, Poshmark, and Depop — on every plan, including a free tier with no credit card. Get instant push notifications the moment a listing matches your saved search, so you reach deals before other buyers. Build precise filters with AND/OR and price-range logic plus seller and location exclusions. AI search assist turns plain English into exact filters. Use PHLAUNCH50 for 50% off Premium for 3 months.
Hey Product Hunt — JD here, solo founder of DealHunter.
Three years ago I was hunting for underpriced GPUs, Pokémon cards, and local marketplace flips, and I kept losing the best deals because they'd sell within minutes. I had seven browser tabs open, each with a different search syntax, and I'd still miss listings overnight.
So I built the tool I needed: one alert layer sitting on top of every resale marketplace.
DealHunter monitors Mercari, eBay, Facebook Marketplace, Poshmark, Craigslist, OfferUp, and Depop simultaneously. You create a saved search once, and the moment a matching listing appears anywhere, you get a push notification. No tab-checking, no missed deals.
A few things that make it different:
AI Search Assist Type "RTX 4090 under $900 near me, exclude broken or parts-only" or "sealed Pokémon booster boxes under market price" in plain English, and our AI converts it into precise keyword filters across every marketplace. Most alert tools force you to learn each platform's search syntax. We don't.
Burst-on-creation The second you save a search, every enabled marketplace fans out in parallel and results stream in within 40 to 100 seconds. You see the product working immediately, not in a 24-hour digest.
All plans include all 7 marketplaces No "this site is locked to the top tier" gating. Plan differences are saved search count, alert speed, and live search limits — never which marketplaces you can use.
Real-time push to web, iOS, Android, or email Customize cadence per saved search: instant for high-value items, hourly digest for casual hunts.
Plans: Free, Basic, Standard, and Premium. Free includes 1 saved search and 3 AI queries per day. Premium unlocks 20 saved searches, 100 live searches per day, and the fastest alert cadence.
Product Hunt launch offer: use code PHLAUNCH50 for 50% off Premium for the first 3 months. Valid through August 31, 2026.
I'll be in the comments all day.
Genuine question for the community: what's the most frustrating thing about deal-hunting or reselling for you right now? Platform-specific quirks, missing alert features, workflow pain — I'm taking notes for the roadmap.
