QUICK ANSWER
Yes — Keepa Power User at €19/month is the most cost-effective tool in any serious UK FBA stack. The free version hides Sales Rank history, which is the one data point that actually drives sourcing decisions. Without it you're guessing whether a product sells. With it, you're making informed decisions in 60 seconds. The subscription pays for itself in the first deal you correctly avoid because you spotted a problem the free version would have hidden.
This is a tool review, not a tutorial. If you want the chart-reading playbook — green line, blue line, OOS, buy-box rotation — that lives in the Keepa Tutorial UK. This piece focuses on the value question: what does the paid version unlock, and is it worth the spend?
What Keepa actually is
Keepa is the price-and-sales-rank database for Amazon. Every product on every Amazon marketplace has a complete price history, sales rank history, offer count history, and buy-box history archived in Keepa's backend. The browser extension overlays this on Amazon product pages; the website hosts deeper search and analytics tools.
Two main use cases for FBA sellers:
- Validate a deal you're already considering. Pull up the Keepa chart, check sales velocity, watch for Amazon dominance, confirm the price you're seeing is durable. 60 seconds, walk away from 70% of bad deals.
- Source new deals from scratch. Use Product Finder to query Amazon's catalogue against criteria you define — sales rank, price band, offer count, OOS frequency — and surface ASINs that match a sourcing thesis. This is the underused side of Keepa.
Free vs Power User — what €19 unlocks
Keepa's free tier is a tease. It shows you the price chart and calls it a day. Without Sales Rank history you have no way to know whether a product actually sells, which means you can't make a sourcing decision with the free version no matter how clever the rest of your process is.
Here's what Power User adds:
- Sales Rank history — the single most important data point. Without it, you're guessing.
- Product Finder — the database query tool. Filter by sales rank, price, offer count, OOS%, brand, category, and dozens more. Save and rerun queries.
- Advanced chart features — full chart range (free is limited), additional data overlays (review counts, price drops, BSR drops over time), buy-box analysis depth.
- Price drop and availability alerts — get notified when a product hits a target price or comes back in stock. Useful for restocks and OOS-arbitrage opportunities.
- API access — if you build internal tooling, Keepa's API is genuinely well-designed. Pull historical data programmatically into spreadsheets, dashboards, or custom analytics.
- Higher token allowance for API and Product Finder queries.
HONEST TAKE
Free Keepa is essentially marketing for paid Keepa. It shows you what's missing without fixing the gap. If you're sourcing on Amazon at all and not subscribed, you're playing on hard mode for no good reason.
The features I actually use daily
1. The Keepa chart (in-extension overlay)
Browser extension overlays the chart directly on every Amazon product page. Open ASIN, glance at chart, decision. The fastest sourcing flow in any tool I use. The chart-reading tutorial covers the specifics.
2. Product Finder for sourcing leads
Product Finder is where Keepa stops being a validation tool and becomes a sourcing tool. I run three saved queries weekly:
- RA candidates — UK marketplace, sales rank under 50K in a category I know, offer count 5–15, OOS% over 10%, last sale within 7 days.
- A2A flips — products where Amazon has been the dominant seller and price has been stable for 90+ days, with a multipack version available at a per-unit discount.
- Replenishables — sales rank stable over 180 days with minimum 30 sales/month, no Amazon-as-seller dominance, single brand.
Most Keepa users never touch Product Finder. That's a mistake — it's the closest thing to a "find me deals" button Amazon FBA has.
3. Price drop alerts
Set alerts on ASINs you'd buy at a target price. Keepa emails or pushes when the price drops. Useful for restocking the same SKU when a supplier promo lands.
4. The deal page
Keepa's main "Deal" page is a feed of recent price drops across the marketplace. I rarely use it directly — too noisy — but it's a useful pulse-check on category dynamics. Better used as a barometer than a sourcing tool.
5. Browser extension cross-references
On any Amazon page the extension shows the offer history, recent buy-box winners, the rank chart, and seller-by-seller appearance. Three clicks, full picture. This combined with SellerAmp SAS handles 95% of validation decisions.
Product Finder — the part most sellers ignore
If you only learn one thing from this review, learn this: Product Finder is the underused side of Keepa Power User. Most sellers buy the subscription for the chart, never figure out Product Finder, and ignore 60% of what they're paying for.
The mental model: Product Finder is a SQL query against Amazon's catalogue. You define filters (sales rank between X and Y, price between A and B, offer count under C, OOS% over D, brand not in [E, F, G]), Keepa runs the query, you get a list of matching ASINs. Save the query, rerun it weekly, you have a continuously refreshed lead list.
Build three saved queries that match your buying thesis and Product Finder turns into the most consistent source of leads in the UK FBA stack. The Method FBA Operating System ships with the exact filter recipes I use, including the brand-exclusion lists that turn a generic search into a clean lead list.
Pricing — what €19/month actually costs
Power User at €19/month (annual billing reduces this slightly). UK sellers pay roughly £16/month at current FX. That's the equivalent of one missed deal a quarter.
Keepa offers higher tiers (Business, Enterprise) which mostly increase API token allowances. For 99% of FBA sellers, Power User is the right tier — only upgrade if you're hitting API limits, which you'll know if it happens.
Alternatives
CamelCamelCamel. The original Amazon price tracker. Free. Decent for casual price tracking. Lacks sales rank history, Product Finder, and the depth of analytics. Fine if you're not actually sourcing FBA stock — useless if you are.
SellerAmp SAS. Pulls Keepa data inline alongside its own fee/profit analysis. Pairs with Keepa rather than replacing it. Most serious UK sellers run both.
Direct Amazon data. Seller Central shows historical pricing for products you've sold. Useless for products you haven't yet sold, which is most of them when you're sourcing.
BuyBotPro. An automated decision tool that uses Keepa as its underlying data source. If you want fewer manual chart reads, BBP can speed up high-volume sourcing — but you still need Keepa underneath it.
Bottom line: there's no real Keepa replacement for serious sourcing. Everything else either uses Keepa data or solves a different problem.
When NOT to subscribe
Honest answers, not "everyone needs it":
- You're not actually sourcing yet. If you're still in research mode and haven't placed your first order, free Keepa for browsing is fine. Subscribe the week before your first sourcing session, not now.
- You only sell private label. If your model is design-and-launch your own brand, you mostly care about your own listings — Seller Central and Helium 10 cover that better. Keepa is overkill.
- You source exclusively wholesale with established suppliers. If you have direct supplier relationships and source the same SKUs every month, the chart matters less than your supplier pricing. Power User is still useful for new SKU evaluation but not as critical.
My verdict
Keepa Power User is the highest-ROI single subscription in any UK Amazon FBA stack. €19/month, no contract, cancel anytime. If you're sourcing — RA, OA, A2A, wholesale evaluation — it's the bedrock data layer. Skip every other tool before you skip Keepa.
The two practical recommendations: (1) subscribe before your first real sourcing session, not after, and (2) invest a Saturday afternoon learning Product Finder properly. Doing both will collapse the time-from-zero-to-first-profitable-deal more than any other single tool decision you can make.

VISIT KEEPA →Frequently asked questions
Is Keepa worth €19 a month for UK Amazon sellers?
Yes — Sales Rank history alone justifies it. Free Keepa hides this data, which makes the free version actively misleading for sourcing. The Power User cost is recouped the first time you correctly avoid a bad deal.
What's the difference between free Keepa and Power User?
Free shows price history and the chart overlay. Power User adds Sales Rank history, Product Finder, advanced filters, alerts, full chart range, and API access. For sourcing, Power User is required.
Can I use Keepa for UK Amazon (amazon.co.uk)?
Yes. Set the default domain to amazon.co.uk in Keepa settings. UK data quality is excellent and matches US-marketplace depth.
What's better than Keepa for Amazon UK?
Nothing, currently. CamelCamelCamel is the closest free alternative but lacks the critical Sales Rank data. SellerAmp SAS pairs with Keepa rather than replacing it.
How does Keepa Product Finder work?
Database query tool — filter Amazon's catalogue by sales rank, price, offer count, OOS%, brand, category, and dozens more criteria. Save filters, rerun queries, surface matching ASINs. Underused by most Keepa subscribers.
