Dipper and Keepa are two of the most talked-about price trackers — but they are built for different jobs. Keepa is the definitive tool for Amazon price history. Dipper is an AI price tracker for almost any store. This guide compares them honestly so you can pick the right one (or use both).
Quick verdict: Choose Keepa if you live on Amazon and want the deepest possible price history and seller data. Choose Dipper if you buy across many stores and want one tracker that works everywhere, tells you when a price is actually a good deal, and can even find a cheaper option. They complement each other well.
What is Keepa?
Keepa is an Amazon-focused price-tracking service made up of a website, a browser extension, and an API. Its signature feature is the interactive price-history graph it overlays on every Amazon product page — showing the Amazon price, third-party new and used prices, and the sales rank over months or years. Keepa also offers price-drop and availability alerts, a product finder, deal listings, and a paid data subscription used heavily by Amazon sellers and resellers for research and automation.
Keepa's strength is depth. For Amazon specifically, nothing tracks history as far back or in as much detail. If you are an FBA seller, a reseller sourcing on Amazon, or a shopper who wants to know exactly how an Amazon price has moved over the last two years, Keepa is exceptional — and largely irreplaceable.
Its limitation is also its focus: Keepa only works on Amazon. Open a product on Walmart, Target, eBay, Nike, Zara, or a small Shopify store, and Keepa has nothing to show — it isn't built for those sites.
What is Dipper?
Dipper is an AI price tracker built around a simple idea: read the price from the page you're already viewing. Because the Dipper browser extension runs in your real browser, it can capture the price on almost any store — including stores that block ordinary price-scraping bots. You click once to start tracking, choose how you want to be alerted, and Dipper watches the price for you.
On top of tracking, Dipper adds two things most trackers don't: Smart Track, an AI that compares the live price to its real history and tells you when a drop is genuinely a good deal (not a fake "sale"), and Find cheaper, which searches the web for the same or a similar product at a lower price. Alerts arrive by email, browser push, or Telegram.
Dipper vs Keepa: feature comparison
| Feature | Dipper | Keepa |
|---|---|---|
| Stores supported | Almost any store (Amazon, Walmart, Target, eBay, Etsy, Zara, Nike, Shopify…) | Amazon only (all Amazon marketplaces) |
| Amazon price history depth | Tracks from when you add it (current price forward) | Best in class — years of granular history |
| Deal intelligence (is it a real deal?) | Yes — Smart Track AI deal scoring | Manual, from reading the history graph |
| Find a cheaper option elsewhere | Yes — AI cross-store search | No |
| Alert channels | Email, browser push, Telegram | Email, app, some Discord/Telegram community bots |
| Browser extension | Yes (1-click add on any product page) | Yes (Amazon overlay) |
| Seller/reseller research (API, CSV, product finder) | Basic; consumer-focused | Extensive — a core strength |
| Free tier | 5 products, daily checks, no card | Free graphs + basic alerts; data subscription paid |
| Best for | Everyday shoppers & resellers tracking across many stores | Amazon power users & FBA sellers who need deep history |
Where Keepa wins
- Amazon price history depth. Years of granular data, third-party and used prices, and sales-rank history. Unmatched for Amazon research.
- Seller tooling. The API, CSV exports, and product finder are built for FBA sellers and resellers operating at scale on Amazon.
- Maturity. Keepa has been the Amazon standard for years and has a large, data-rich ecosystem.
Where Dipper wins
- Works on almost any store. The single biggest difference. Dipper isn't limited to Amazon — it tracks Walmart, Target, eBay, Etsy, Zara, Nike, Shopify shops and more, because it reads the price you see.
- Tells you when it's actually a deal. Smart Track scores the price against its real history so a fake markdown never fools you.
- Finds a cheaper option. Dipper's AI searches other retailers for the same or a similar product at a lower price.
- Alerts your way. Email, browser push, or Telegram — and back-in-stock alerts that actually work.
- One-click simplicity. Click the icon on any product page and you're tracking — no spreadsheets, no per-store setup.
Pricing comparison
Both offer a free way in. The difference is what "paid" buys you: Keepa's subscription is aimed at data/seller use; Dipper's plans are aimed at tracking more products more often.
| Plan | Dipper | Keepa |
|---|---|---|
| Free | 5 products, daily checks, email alerts, no card | Price-history graphs + basic Amazon price-drop alerts |
| Paid entry | Plus — $12/mo (40 products, 6-hour checks, unlimited Smart Track) | Keepa Data — ~€19.90/mo (API, product finder, exports) |
| Higher tiers | Pro $24/mo, Business $49/mo (more products, faster checks, team seats) | Higher API token allotments |

Which should you use?
Use Keepa if your world is Amazon: you're an FBA seller, a reseller sourcing on Amazon, or a shopper who wants the deepest possible Amazon price history and doesn't need to track other stores.
Use Dipper if you buy across many stores and want one tracker that works everywhere, tells you when a price is genuinely a good deal, alerts you the way you prefer, and can find a cheaper option. It's the better everyday tracker for most shoppers.
Use both if you're a serious deal-hunter or reseller — Keepa for deep Amazon research, Dipper for tracking everything else plus AI deal scoring.
Verdict
Keepa isn't beaten at what it does — Amazon price history — and probably never will be. But "the best price tracker" for most people isn't an Amazon-only tool. If you want to watch a jacket on Zara, sneakers on Nike, electronics on Walmart, and a deal on Amazon from one place, Dipper is the tracker built for that, with AI on top. For everyday shoppers and cross-store resellers, Dipper is the more practical choice; for Amazon specialists, Keepa remains essential. They're not really rivals — they're complements.
