DeaLynx
Price history & real-deal alerts for French online stores
Keepa & CamelCamelCamel are great — but Amazon-only and US-centric. DeaLynx brings deep price history, a 0–100 deal score (that flags fake promos), price/stock alerts and cross-store comparison to French e-commerce: Amazon, Fnac, Cdiscount, Darty, Boulanger, Leboncoin… Plus a free, no-account browser extension that shows the verdict right on the product page. Track products and whole searches. Freemium. Would love your feedback 🙏
Hey Product Hunt 👋
I'm Mathieu, the maker of DeaLynx.
Like a lot of people, I kept getting burned online: buying something only to watch it drop 30% two weeks later, or seeing a "-50%" banner on a price that had quietly been inflated first. Keepa solved this beautifully… but only for Amazon. Everywhere else in France — Fnac, Cdiscount, Darty, Leboncoin — I was flying blind.
So I built DeaLynx: price & stock tracking across French e-commerce, not just one marketplace.
- 📈 Real price history on any product, so you can see if today's "deal" is actually a deal
- 🧠 A deal verdict at a glance (good price vs. inflated) based on the real curve
- 🔔 Alerts when a price drops or an item is back in stock
- 🧩 A browser extension (Keepa-style) that shows the history right on the product page while you shop
- 🔎 You can even track a whole search/listing, not just a single product
What changed the most during the build: I started Amazon-only, but quickly realized the real pain in France is the fragmentation across dozens of shops. That pushed me toward a hybrid scraping approach and a crowdsourced extension — each user browsing naturally helps keep prices fresh for everyone.
It's freemium, and today's launch is really about getting honest feedback from people who shop online a lot. What would make you actually trust a "good deal" badge? I'm reading every comment 🙏
