Keepa is an Amazon price tracking and data service that serves two audiences: individual consumers who want to time purchases to genuine price drops, and Amazon sellers/researchers who need deep historical data to evaluate product opportunities. The browser extension is free; the Premium subscription (approximately $19/month or $189/year) unlocks the features that matter most for professional use.
For casual Amazon shoppers, the free Keepa extension alone is sufficient to show basic price history and avoid the common Amazon trick of inflating then "discounting" prices. For deal hunters or sellers, Keepa Premium is genuinely transformational.
What Keepa shows — free version
- Price history charts on every Amazon product page. See the last 90 days, 180 days, 1 year, or all-time pricing.
- Amazon vs third-party seller pricing. Distinguish when Amazon is direct-selling vs third-party shipping.
- Buy Box history. See which seller has historically won the Buy Box.
- Deal alerts (limited). Save products and receive email alerts when prices drop (quota-limited on free tier).
Keepa Premium unlocks
- Unlimited deal alerts. Track hundreds of products simultaneously.
- Sales rank history. See how a product's Amazon rank has moved over time — critical for sellers evaluating opportunities.
- ML-inferred demand estimates. Approximated monthly sales volume on products (useful for sellers; interesting for shoppers).
- Product finder / research tools. Filter Amazon's catalog by criteria (sales rank range, review count, price band, category).
- Seller database. Identify seller reputation, feedback trends, multi-listing analysis.
- API access. Programmatic queries for integration with sellers' internal workflows.

Who should pay for Keepa Premium
- Amazon sellers or arbitrage researchers.
- Deal hunters tracking 25+ products concurrently with strict price-drop alerting.
- Consumers who buy frequently and want comprehensive price-history data before large purchases.
Who should stick with free Keepa
- Occasional Amazon shoppers who just want "is this actually a deal?" price history on individual products.
- Casual shoppers with limited alert needs.
Who should use CamelCamelCamel instead
- Strict consumer-side users who want straightforward price tracking without seller-focused features.
- Users who never plan to upgrade to paid and want the cleanest free-tier experience.
Power user tips
- Set realistic alert thresholds. Alerts at "20% below current" catch most meaningful drops; alerts at "1% below current" generate noise.
- Use sales rank trends (Premium). A product at 95th percentile price with rank climbing suggests an arbitrage window about to close.
- Leverage the data for returns. If Amazon drops the price within 30 days of your purchase, Amazon will often price-match; Keepa data supports the claim.
- Bulk-upload watchlists. Premium supports CSV import for hundreds of ASINs at once.
Common pitfalls
- Historical lowest-ever isn't actionable in isolation. A product at its lowest-ever price might still be a bad deal if the item is outdated or the seller is liquidating.
- Third-party seller noise. Keepa shows all seller pricing, which can inflate apparent volatility. Filter to "Amazon" or "Buy Box" pricing for realistic consumer data.
- Keepa only tracks Amazon. For cross-merchant price comparison, combine with Capital One Shopping or manual comparison.
FAQ
Is $19/month worth it for a consumer?
Depends on spend. If you spend $500/month on Amazon and can use historical data to avoid even one bad timing decision, Keepa Premium pays for itself. If you spend $100/month, the free version is sufficient.
Can I buy Keepa Premium for just one month?
Yes. Monthly subscription billing is month-to-month. Cancel anytime; service continues to the end of the billing period.
Does Keepa work outside the US?
Yes. Keepa supports Amazon US, UK, Germany, France, Italy, Spain, Japan, and others. Each regional Amazon has its own price history.
Does Keepa scrape / violate Amazon's terms?
Keepa operates using Amazon's official Product Advertising API and public price data. Amazon has historically tolerated such services; Keepa has operated for 10+ years without significant disruption.
