Keepa charts the price history of Amazon products across 11 stores and pings you when a price drops or stock comes back. Shoppers use it to spot fake deals, and sellers use its sales rank and Buy Box history to judge demand. Its prices couldn't be read, so check those on keepa.com first. - **Value for money: C.** No price on record: Keepa's pricing loads only inside its web app, which our reader couldn't open. With nothing published to compare, it sits at C, the grade for no stated price. - **Free plan and trial: B.** The site, browser extensions and phone apps are free for price history charts and price-drop alerts. That's plenty for shoppers. Which seller data needs a paid subscription isn't confirmed, so sellers may hit a limit we can't see. - **Features: C.** It does price and market history fully: charts going back years, price and stock alerts, sales rank, Buy Box and offer history, a barcode scanner and an API. It's data only, though, with no profit, inventory, listing or ad tools. - **Ease of use: A.** 4.8 from 1,539 App Store ratings. Add the extension and the chart sits on every Amazon product page, and the phone app checks prices by barcode in a shop. - **Platforms and integrations: B.** Web, extensions for Chrome, Firefox and Edge, and iPhone, iPad and Android apps, plus a developer API. There's no desktop app, which is what an A needs here. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Keepa's own pages on 18 October 2026, and its App Store rating. keepa.com shows nothing outside its web app, so we checked its App Store listing instead, which still lists it free. Not based on using the product, and shorter than our full reviews. ## Where it stands among Amazon seller tools - Keepa's GPA of 2.8 is higher than 16 of the 16 other Amazon seller tools we grade. - It stands best on ease of use (A, above 16 of 16) and worst on features (C, above 1). The category's chart of price against score: https://toolgpa.com/charts/amazon-sellers ## Keep it, or make your own? **Keep it.** To replace Keepa you would be making data from Amazon's seller tools and years of sales estimates. That is not a weekend's work, with an AI app builder or without one. It is one of the better ones too: its GPA of 2.8 is higher than 16 of the 16 other Amazon seller tools we grade. - You could not: Data from Amazon's seller tools and years of sales estimates. - You could not: Scanning barcodes with a phone camera or a scanner. - You could not: A real app for iOS and Android. Something home-made would be a web page. - You could not: It plugs into other products, Amazon, Google Chrome and Mozilla Firefox among them, and has an API. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
