You spot a product on Amazon France at 34,99 €. Looks reasonable, but is it? That same item might be 27 € on Amazon Germany today, or it might have been 22 € last month and is now artificially inflated ahead of Prime Day. Without a price history tool that covers all 13 major Amazon EU marketplaces at once, you are essentially shopping blind. Histozon is a free Chrome extension that overlays full price history charts directly on every Amazon product page, across FR, DE, IT, ES and UK, and lets you compare prices cross-country in seconds, no account, no spreadsheet, no guesswork.
What Histozon does for Amazon shoppers in Europe
Histozon is a browser extension built specifically for the European Amazon ecosystem. While most price-tracking tools were designed around Amazon.com and bolt on EU support as an afterthought, Histozon treats the 13 Amazon stores, Amazon.fr, Amazon.de, Amazon.it, Amazon.es and Amazon.co.uk, as first-class citizens.
The core features include:
- Price history charts going back up to 90 days on tracked products, showing new, used and Amazon-fulfilled price lines separately
- Cross-country price panel that shows the current price for the same ASIN on all 13 stores simultaneously, with live currency conversion
- Price drop alerts via browser notification when a product hits your target price on any of the 13 marketplaces
- All-time low / all-time high badges displayed inline on the Amazon product page
- Deal score that rates the current price against its historical range (0 to 100)
Everything is visible without leaving the Amazon product page. No copy-paste of ASINs into a third-party website, no tab-switching between five different national stores.
How Histozon tracks prices across 13 Amazon stores
Each time you open a product page on any supported Amazon marketplace, the extension reads the ASIN and queries Histozon's price database in the background. The database is updated multiple times per day for products with active user interest, and at least once every 48 hours for the full catalogue.
The price chart rendered on the page shows three distinct data lines:
- Amazon price (sold and dispatched by Amazon)
- New price (lowest third-party new offer)
- Used price (lowest used offer, condition "Good" or better)
Data depth varies by product age and tracking history: most popular electronics and household items have 12 to 90 days of data available. Niche products added recently may start with 30 to 90 days.
For the cross-country panel, Histozon resolves the equivalent ASIN on each of the 13 stores, because Amazon sometimes uses different ASINs for the same product across markets, and fetches the current price for each. Currency conversion uses the ECB daily rate, so the comparison is always apples-to-apples in your local currency.
Drop alerts are stored locally in the extension and fired by your browser, meaning no email address is required to use the alert feature on the free tier.
The cross-EU comparison feature (what sets Histozon apart)
This is the feature that no mainstream price tracker replicates properly. When you visit a product on Amazon.fr, a compact panel appears below the main price block showing the current price on Amazon.de, Amazon.it, Amazon.es and Amazon.co.uk, all converted to euros (or to GBP if you browse from .co.uk).
Why does this matter in practice?
- The same Sony headphones frequently cost 15 to 40 € less on Amazon.de than on Amazon.fr, and both ship to France with Prime
- Kitchen appliances from Italian brands are often cheapest on Amazon.it
- Amazon.co.uk after the pound's fluctuation can be surprisingly competitive even accounting for VAT differences
- Seasonal promotions are not always synchronised: a product on sale in Germany is not necessarily on sale in Spain the same week
The panel includes a direct link to the product on each marketplace, so you can add it to your cart there in one click. For EU residents with a Prime membership valid in multiple countries, or for anyone willing to order from a neighbouring marketplace, this feature alone can pay for years of Pro subscriptions.
No other free tool in 2026 offers this five-country live comparison embedded directly inside the Amazon product page. Keepa covers multiple marketplaces but requires manual switching; CamelCamelCamel has no embedded extension cross-comparison at all.

How to use Histozon (step-by-step)
Getting started takes under two minutes:
- Step 1, Install the extension from the Chrome Web Store (search "Histozon" or use the button on histozon.com). It works on Chrome, Edge and any Chromium-based browser.
- Step 2, Navigate to any product page on Amazon.fr, Amazon.de, Amazon.it, Amazon.es or Amazon.co.uk. The Histozon panel loads automatically below the price block, no configuration needed.
- Step 3, Read the price history chart. Hover over any point to see the exact price on that date. Look for the all-time low badge to know whether today's price is genuinely good.
- Step 4, Check the cross-country comparison panel. If another marketplace shows a lower price, click the link to go directly to that listing.
- Step 5, Set a price alert (optional). Click the bell icon, enter your target price and the extension will notify you when the product drops to that level on any of the 13 stores.
No account creation is required to use the core history chart and cross-country panel. Creating a free account unlocks synced alerts across devices and access to your tracking history dashboard.
Who benefits most from Amazon price comparison across EU countries
The tool is useful for a wider range of people than you might expect:
- Everyday shoppers who want to avoid paying full price for electronics, home appliances or toys, especially in the weeks before Christmas or Prime Day when prices fluctuate daily
- Deal hunters and bargain communities who share price drops on forums, Histozon's deal score and all-time low badge make it easy to verify whether a "deal" is genuinely exceptional
- Amazon resellers and FBA arbitrage sellers who need to track buy prices across multiple EU marketplaces before sourcing stock
- Expats and cross-border shoppers living near a national border who routinely compare FR and DE, or ES and FR, before ordering
- Small business owners purchasing office supplies or equipment who want to source from the cheapest EU Amazon marketplace that still offers business invoicing
The cross-EU arbitrage guide on our blog covers the reseller use case in detail, including VAT implications by country.
Histozon vs Keepa (the real differences)
Keepa is the most established Amazon price tracker and has deep data going back many years. It is a solid tool, but several key differences matter for EU shoppers in 2026:
- Price: Keepa's useful features (chart access, API, alerts) sit behind a 19 €/month subscription. Histozon's core features, history chart, cross-country panel, drop alerts, are free.
- Cross-country panel: Keepa shows history per marketplace but does not display a side-by-side five-country comparison embedded in the product page the way Histozon does.
- Ease of use: Keepa's interface is data-dense and targeted at power users. Histozon is designed for the mainstream shopper who wants a quick "is this a good price?" answer without reading documentation.
- Data depth: Keepa wins on historical data volume, years of granular price points. Histozon covers 90 days for most products, which is sufficient for the vast majority of purchasing decisions.
Full breakdown on the Keepa alternative page.
Histozon vs CamelCamelCamel (key differences)
CamelCamelCamel (3Camels) is the other major free tracker, popular for Amazon.com and with limited EU support:
- EU focus: 3Camels was built for Amazon.com and the EU experience remains secondary. Histozon was built EU-first.
- Embedded extension: 3Camels requires you to visit their website and paste an ASIN or URL. Histozon works inline on the Amazon page with zero extra steps.
- Cross-country comparison: 3Camels has no equivalent feature. This alone is a decisive difference for any shopper active across multiple EU Amazon stores.
- Alerts: Both offer price drop alerts; Histozon's are browser-native (no email required for the free tier), while 3Camels requires an email address.
See the full comparison on the CamelCamelCamel alternative page.
Free vs Pro (what you get at each tier)
Histozon follows a free-first model. The free tier is genuinely useful and not artificially crippled:
- Free: full price history chart (up to 90 days), full cross-country comparison panel, up to 30 active price alerts, deal score badge, all-time low / all-time high indicators. No account required for chart and comparison.
- Pro: unlimited active alerts, alert sync across devices, bulk tracking dashboard (monitor up to 500 ASINs simultaneously), CSV export of price history, priority data refresh (products tracked by Pro users are updated more frequently), and early access to new marketplace additions.
Pro pricing is available on the Histozon website. For most individual shoppers, the free tier covers every day-to-day need. Pro is aimed at resellers, deal community curators and power users tracking large product catalogues.
Privacy (what data Histozon collects)
The extension reads the ASIN of the product page you are currently viewing in order to retrieve price history data. It does not read your Amazon account details, your order history, your search queries or any other page content. ASINs are sent to Histozon's servers to query the price database, this is technically necessary for the tool to function.
No personally identifiable information is collected in the free tier without an account. If you create an account to sync alerts, your email address is stored and tied to your alert list. Full details are in the privacy policy on histozon.com. The extension does not use third-party advertising trackers.
Frequently Asked Questions
Which Amazon marketplaces does Histozon support?
Histozon currently supports 13 Amazon stores: Amazon.fr (France), Amazon.de (Germany), Amazon.it (Italy), Amazon.es (Spain) and Amazon.co.uk (United Kingdom). The cross-country comparison panel shows live prices from all 13 stores simultaneously whenever you visit a product page on any of these marketplaces. Support for additional European countries is planned for future updates.
How far back does the price history go?
For most popular products, electronics, home appliances, books, toys, price history goes back 12 to 90 days. Products with lower search volume or recently added to Amazon may have shorter history, starting from the date Histozon first began tracking them. Data depth continues to grow over time as the database matures. The chart always shows the full available history range for each product.
Is Histozon really free, or is the free version limited?
The core features, price history chart, cross-country comparison panel, deal score and all-time low badge, are completely free with no account required. The free tier allows up to 30 active price drop alerts. Pro unlocks unlimited alerts, multi-device sync, bulk tracking for up to 500 ASINs and CSV export. The free tier is not a trial; it does not expire and does not require a credit card.
Does Histozon work for used and third-party seller prices?
Yes. The price history chart shows three separate data lines: the Amazon-sold price, the lowest new third-party offer and the lowest used offer (condition "Good" or better). You can toggle each line on and off to focus on the price category relevant to your purchase. The cross-country comparison panel shows the lowest available new price (Amazon or third-party) for each marketplace.
Can I use Histozon on browsers other than Chrome?
Histozon is available on any Chromium-based browser, including Google Chrome, Microsoft Edge, Brave and Opera. A Firefox version is in development. Safari is not currently supported. The extension installs in seconds from the Chrome Web Store and works immediately on all 13 supported Amazon marketplaces without any configuration.
How does the cross-country comparison handle currency differences?
The extension uses the European Central Bank daily exchange rate to convert all prices into the currency of the marketplace you are browsing. If you are on Amazon.fr, prices from .de, .it and .es are already in euros and shown as-is; the Amazon.co.uk GBP price is converted using the current EUR/GBP rate. The conversion rate used and its date are displayed in the panel so you can verify the calculation independently.
