Features & Specs

  1. Hourly Alerts

    We re-check every saved search and watched listing every hour, then email or push you the moment a price drops or a new match shows up. eBay batches its own alerts on its schedule.

  2. Deal Scoring

    See how a listing's price stacks up against similar active listings. Anything 20% or more below the average asking price gets flagged as a hot deal, 10 to 20% below as a good price.

  3. Price History

    Watch an item and we record its price every six hours, so you can tell whether it is drifting down or holding firm. eBay listing pages show you no price chart at all.

  4. Auction End Alerts

    Get a heads up when a watched auction enters its final 24 hours, plus optional countdown alerts at 1 hour, 30, 15, and 5 minutes that you set per item.

  5. Image Search

    Snap or upload a photo and we find matching eBay listings, so you can hunt for something you can picture but cannot name.

Questions & Answers

As answered by people managing FindersKeepers.app.
  1. What makes FindersKeepers.app unique?

    Two things eBay does not give you, in one place.

    Alerts run on a fixed hourly schedule instead of eBay's own batching, so you hear about a price drop or a new match while it is still actionable. And every item you watch gets a price history, recorded every six hours from the day you add it, which eBay listing pages do not offer at all.

    On top of that, listings are scored against similar active listings in the same search, so you see whether an asking price is actually good instead of just seeing a number. Twenty percent or more below the average is flagged as a hot deal.

    All of it is free, with no paid tier, and you can search eBay through FindersKeepers without an account or an eBay login.

  2. Why should a person choose FindersKeepers.app over its competitors?

    Because it covers the whole job for free, and it tells you when another tool is the better pick.

    Most eBay tools do one piece well. WatchCount reads real sold data. Madealert pushes alerts within seconds of a listing appearing. eBay's own saved searches are already built into the site you are shopping on. FindersKeepers puts hourly alerts, price history, deal scoring, auction countdowns, saved searches, seller watchlists, image search, and collection tracking together at no cost, on US and international eBay marketplaces.

    We also publish comparison pages against nine other tools, written in-house, including the parts where the other tool wins. Madealert beats our hourly check on speed and the page says so. That is the same standard the blog holds: every factual claim about how eBay works links to the eBay help page it came from.

  3. How would you describe the primary audience of FindersKeepers.app?

    Collectors and bargain hunters who shop eBay regularly. Trading cards, watches, coins, video games, vinyl, retired LEGO sets, Funko Pops, vintage clothing, ex-corporate hardware.

    These are buyers, not sellers. They already have a mental want list and a rough sense of what a fair price looks like, and they are tired of refreshing the same search, missing an auction by twenty minutes, or finding out later that the listing they passed on was actually underpriced.

    The common thread is caring about paying the right price for one specific thing, rather than browsing deals in general.

  4. Which are the primary technologies used for building FindersKeepers.app?

    Next.js on the App Router, with React and Tailwind on the front end, deployed on Vercel.

    Listing and pricing data comes from eBay's APIs. A scheduled job re-checks every saved search and watched item on a fixed hourly cadence, records watched-item prices every six hours, and computes deal scores against the comparable active listings in the same search. Alerts go out over email and web push.
