Spycost

In plain words

Spycost is a shopping tool that tracks price history to reveal whether discounts are genuine deals or manipulated pricing tactics. It shows users the full price context, including previous costs and price fluctuations, so they can determine if a purchase is actually a good value. The tool is designed for consumers who want to make informed shopping decisions by seeing beyond advertised discounts.

From the sources

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.

Track prices from any online store, view price history, and get instant price drop alerts. Never overpay again with SPYCOST.

SPYCOST automatically monitors prices across any online store, tracks price history , and sends price drop alerts the moment a better deal appears. The first version is coming to an end, but the idea behind SPYCOST is still alive. We are taking a pause to rethink the product and build the second version from scratch. We listened closely to our users and their feedback, and decided to rethink the direction of SPYCOST. This was not an easy decision, but we are shutting down the first version and starting work on a new second version from scratch. Please check this website from time to time for updates. As soon as the second version is available, we will announce it here. For any additional…from spycost.com

  I built a tool that watches webpages and exposes changes as RSSMar 2026 · sitespy.app · ▲320

  I built Site Spy after missing a visa appointment slot because a government page changed and I didn’t notice for two weeks. It watches webpages for changes and shows the result like a diff. The part I think HN might find interesting is that it can monitor a specific element on a page, not just the whole page, and it can expose changes as RSS feeds. So instead of tracking an entire noisy page, you can watch just a price, a stock status, a headline, or a specific content block. When it changes, you can inspect the diff, browse the snapshot history, or follow the updates in an RSS reader. It’s…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
