Keepa Review 2026 — Is It Worth $19/Month for Amazon Sellers?
Keepa prevents the most expensive mistake in retail arbitrage: buying inventory on a temporary price spike. Here's exactly what it shows, how to read the charts on a sourcing run, and the math on whether $19/month makes sense for your volume.
What Is Keepa?
Keepa is an Amazon price tracking tool that shows the historical price of any Amazon product over time. Founded in 2013, it has tracked prices on Amazon US, UK, Germany, Japan, and several other marketplaces — building one of the most complete price history databases for e-commerce products anywhere.
For retail arbitrage, one piece of Keepa data matters more than anything else: the 90-day price chart. If the current Amazon price is a temporary spike — caused by a competitor going out of stock or a brief demand surge — Keepa shows you that. Without it, you're making buy decisions on a snapshot that may not reflect where the price actually trades.
How to Read a Keepa Chart on a Sourcing Run
The Keepa chart has several colored lines. For retail arbitrage on a mobile sourcing run, focus on two:
Is $19/Month Justified? The Math
One bad buy from a price spike costs more than a year of Keepa. Here's the actual math:
| Scenario | Without Keepa | With Keepa |
|---|---|---|
| Buy price (clearance) | $22 | $22 |
| Amazon price (at time of buy) | $45 (spike — real price: $18) | $45 (but Keepa shows real: $18) |
| Decision | BUY ✗ | PASS ✓ |
| Price when you list | $18 (returned to normal) | N/A — you didn't buy |
| Net result | −$4+ loss per unit | $0 — capital preserved |
| Keepa monthly cost | — | $19 |
| Break-even | Keepa pays for itself by preventing 1 bad buy per month on ~$50 of inventory | |
Key Features for Arbitrage Sellers
- 90-day+ price history — the core feature. See every price move on a product for the past 3 months minimum.
- BSR history — not just current rank but how it's moved over time. Tells you if the product sells consistently or in unpredictable bursts.
- Number of sellers over time — spikes in seller count mean competition just increased. Drops mean sellers left and prices may rise temporarily.
- Browser extension — chart overlays directly on Amazon product pages in Chrome or Firefox. No separate tab needed.
- Price drop alerts — set a target price on any product and get notified when it hits. Useful for tracking items you couldn't buy profitably yet.
Keepa vs SellerAmp — Do You Need Both?
| Keepa ($19/mo) | SellerAmp ($19.99–34.99/mo) | |
|---|---|---|
| Keepa price charts | ✓ Full charts | ✓ Built-in (via Keepa API) |
| Mobile barcode scanner | ✗ | ✓ Primary feature |

| Browser extension on desktop | ✓ | ✓ |
| Best for | Desktop research | Mobile store sourcing |
Most sellers who use SellerAmp don't need a separate Keepa subscription — SellerAmp pulls Keepa charts directly into every mobile scan. If you do desktop research before sourcing trips, the standalone Keepa browser extension adds value. If you do everything on your phone in-store, SellerAmp alone covers it.
Verdict
Keepa is worth $19/month for any seller running more than one or two sourcing trips per month. The payoff is not features — it's the avoidance of one bad buy. For mobile-first sellers, SellerAmp includes Keepa and adds everything else you need. Start with the Amazon Seller App → add SellerAmp → add standalone Keepa only if you do significant desktop research.

Keepa tracks the price history of every product on Amazon over time. It shows you a chart of how the Amazon price, third-party seller prices, and Buy Box price have moved over the past 90 days, 180 days, or longer. This tells you whether the current price is normal, a temporary spike, or recovering from a dip.
Keepa costs €19/month (approximately $19–21 USD depending on exchange rate). There is no free tier for price history — the free version only shows limited data. A subscription gives full access to all charts, data exports, and the browser extension.
Yes for any seller doing more than one or two sourcing runs per month. The $19 monthly cost is justified by avoiding a single bad buy. A product that appears to sell at $45 on Amazon but was $18 last month will return to $18 — buying it at clearance for $22 produces a loss, not a profit. Keepa shows you that history before you commit.
Keepa has a mobile browser version but no dedicated iOS or Android app. For mobile sourcing, SellerAmp integrates Keepa charts directly into its scanner — so you see price history per scan without switching apps. Most sellers use SellerAmp (which includes Keepa) on their phone and the Keepa browser extension on desktop for deeper research.
For retail arbitrage targeting Amazon FBA, look for products where the Keepa BSR chart shows consistent ranking under 250,000 in their category without wild spikes. A product that bounces between 50,000 and 2,000,000 sells infrequently and unpredictably — avoid it. Steady BSR under 150,000 indicates reliable sales velocity.
