Remember the last time you bought something at a discount, only to see it later for the same price without the discount? Or when the product costs more today than it did yesterday. Did you feel cheated? Are you ready to look behind the screen of manipulation and lies? Spycost helps you see when you’re paying more while thinking you’re paying less. It gives you the full price picture, so you can decide whether it’s actually worth it.
Hey Product Hunt 👋
I built Spycost because I couldn’t build a clear purchase priority list while being constantly hit with “attractive offers.”
I kept breaking my own priorities because I was buying less important things just because I saw a “discount”.
And later, I kept realizing that the discount I fell for was fake, or not nearly as good as it was presented.
I constantly felt stupid, like I had been robbed by thieves I opened the door for and invited into my home myself.
Spycost is a price tracker that shows you when you’re being fooled, or when the right moment to buy has finally come. At the end of the day, the final choice is still yours.
If you don’t need to buy something right here and now, but you’re only planning to buy it, this is the perfect option for you.
I built Spycost for myself, and I’ll be happy if it helps you too!

Great idea, I wonder do you guys also consider cashback like Rakuten or capital one shopping
"Raise the price first, then slap a discount on it" — feels like scammers all over the world are running the exact same playbook. I've honestly stopped trusting those flashy discount labels on shopping sites; too many times the "deal" was just the inflated price wearing a costume.
So I'm definitely going to give Spycost a try. Hoping this little spy-duck can see through the fake discounts for me and actually guard my wallet for once. Congrats on the launch, Hlib!
This is a very relatable problem. The product seems strongest if it turns “I bought too early” into a simple post-purchase routine rather than another tracker to manage. Do you monitor price drops automatically from receipts or orders, or does the user manually add each purchase?
I don't even trust discounts these days for this exact reason. Will try this out!
Context specific is the right call. What saved us when we stored scraped prices was writing the request context into the same row as the number, so region, currency and whether we were logged in all travelled with it. Before that we lost an afternoon chasing a price drop that turned out to be a different geo answering the same URL.
Love the idea, I've been burned by fake discounts before, but I also wonder how often the best price is worth waiting weeks or months for.
Congrats on the launch, Hlib.
Ran a quick manual QA pass over the site out of habit. One thing worth
checking right now: your Pricing section stays on "Loading available
plans..." and the plan data isn't in the served HTML, so the Pricing
link in your header currently leads to a section with no prices.
Found a few other bits too. Happy to send the write-up over if useful -
free, no strings.
The duck-spy branding got me before I even finished the tagline, nice touch. The thing I kept hitting when I built price scrapers is that a lot of retailers personalize or geo-vary the price now, and some quietly A/B test it mid-session, so 'the price yesterday' isn't one number, it's a spread. Do you snapshot from a fixed region and session so the history stays apples-to-apples, or could two people see different Spycost baselines for the same product? That's the part that decides whether the 'is this a real deal' call actually holds up over time.
Finally something that actually calls out fake discounts! So tired of "limited
time" sales that are always running. This is the kind of tool that makes
shopping way less stressful.
Strong pain point, beautiful solution, and a great launch :) Good job, amigo.
Next Feature Idea: call bullshit on "only X seats left, etc" :P
Price history tracking should be built into every e-commerce site but it never will be because it's bad for business.
this is a real problem, fake discounts are everywhere. genuinely curious about the mechanics though - to know a price history you'd need to have been tracking a product before the "discount" showed up. does it only work for stores/products already in your database, or is there a way to check a price you're seeing for the first time?
Congrats on the launch, Hlib — the spy-duck is perfect for this. One thing I’m genuinely curious about: when I add a product, do I see its price history from before I started tracking (so I can judge today’s “deal” right away), or does the history only build up from the moment I add it?
the duck-as-a-spy branding is doing a lot of work here, it's memorable. question on the price history itself - when I add a product I just found today, do you backfill history from somewhere, or does the chart only start from the moment I add it, so the "is this actually a good deal" signal takes a while to become useful?
This resonates with me. Last November, I waited weeks for a deal on a coffee machine. When the discount finally appeared, something seemed off. I checked a screenshot I had taken earlier, and the "sale price" was the same as it had been a month earlier. They had increased the price just to reduce it again. I really felt manipulated. I wish I had Spycost then. I'm definitely going to try your tool.
Nice concept! Does it work across most online stores, or are you focusing on specific retailers first?
Congrats on the launch! Is it capable of tracking a product CLASS, not just exact single product? A good example would be buying a coffee machine. You know a set of features/parameters you need, but you are open to look at multiple brands.
looks interesting product, what I feel as a difference is exposing the psychology of discounts 😉
Would love a browser extension version so it can auto-track prices while I shop instead of me having to look things up manually every time, would make it way easier to catch those sneaky price jumps in the moment.
