Free vs paid price trackers: which should you use in 2026?

Yes, there are good free price trackers: Keepa and CamelCamelCamel for Amazon, plus the price alerts built into comparison sites such as idealo or leDénicheur for the products they list. For a one-off Amazon purchase, they are often all you need. A paid tracker starts to make sense when you follow several products at different retailers, want history and alerts in one place, or have already been caught by a "deal" that wasn't one.

This guide reviews the free options, what they don't do, and helps you decide without pushing you to pay if you don't need to.

What free price trackers are available?

Here are the main free options for shoppers in France and Europe, as described by their publishers at the time of this update:

Free option	Where it works	Price history	Alerts	Main limitation
Keepa (free version)	Amazon, including Amazon.fr and other countries	Yes, detailed charts	Price drop and back in stock, with a free account	Amazon only; advanced data is reserved for the paid Keepa Pro plan
CamelCamelCamel	Amazon, including Amazon.fr	Yes, charts	Email when the price drops	Amazon only
Comparison-site alerts (idealo, leDénicheur…)	Retailers listed on that comparison site	Depends on the site (leDénicheur shows a history)	Yes, free, often with a target price	Only products and offers the site lists
Retailer wish lists and favourites	One retailer at a time	No	Varies by site, rarely with a target price	No overview, no reliable history
Manual tracking (spreadsheet, notes)	Anywhere	Whatever you write down	None	Time spent and things forgotten

What don't free price trackers do?

Free tools are very good within their own scope. The trouble is everything outside it:

• They are siloed. Keepa and CamelCamelCamel only look at Amazon. If the same vacuum is cheaper at Cdiscount, they won't see it.
• Comparison sites only track what they list. A product or retailer missing from their catalogue can't be watched, and you can't just paste the link of any product page.
• Your watches are scattered. One alert on Keepa, another on a comparison site, a favourite at a retailer: there is no single place to see where your planned purchases stand.
• They show a chart, not a decision. Reading price history takes some practice: spotting the usual price, the spikes, the recurring drops. Drawing the conclusion is up to you.
• They don't tell you when a discount is misleading. An inflated "was" price is still yours to check, using our method to spot a fake discount.

None of this is a deal-breaker. But each gap is paid for in time, or in price drops you never notice.

What does a paid price tracker add?

A paid tool is only worth it if it fills those gaps. Taking the example we know best, here is what UniverTrack actually does, and what it doesn't:

• A link is enough: you paste a product link from Amazon, Cdiscount or another online store (as long as the product page can be read), without depending on a comparison site's catalogue.
• Automatic checks and dated history: the price is checked on a regular schedule; history starts on the day you begin tracking, except on Amazon, where past history can be shown.
• A "good time to buy" indicator that sums up the chart, plus email alerts when your target price is reached.
• Depending on the plan: fake-discount detection and an AI buying assistant (Malin), grouping the same product added from several retailers on one page with the best offer (Pro), back-in-stock alerts (Expert).

To be clear about the limits: the tool does not automatically search every shop for a product, and it has no official integration with Fnac, Darty or Boulanger. It tracks the links you add.

Free or paid: which fits your profile?

Your situation	Our recommendation
One purchase a year, on Amazon, no rush	Free is enough: Keepa or CamelCamelCamel with an alert
A mainstream product well covered by comparison sites	Free is often enough: an idealo or leDénicheur alert
A big purchase (TV, appliance) available at several retailers	Paid is useful, at least for the duration of the purchase
A list of several products to watch over time	Paid recommended: everything in one place
You distrust struck-through prices on Black Friday or during sales	Paid, with fake-discount detection
You very rarely shop online	No need to pay

When is a free price tracker really enough?

Let's be straight: if you buy one or two products a year, those products are on Amazon and you're in no hurry, you probably don't need a subscription. Open a free Keepa or CamelCamelCamel account, set an alert at a sensible price using the history, and wait. Our guide to Amazon price history shows how to read those charts.

Likewise, for a very common product (a well-known smartphone, a games console), the free alerts on comparison sites already cover plenty of retailers.

When does paying for price tracking make sense?

The maths changes as soon as one of these applies:

1. You follow several products at once (furnishing a home, holiday gifts) and juggling three tools makes you lose track.
2. The product sells outside Amazon and isn't well covered by comparison sites, or you want to watch one specific listing at one specific retailer.
3. The purchase is expensive: on a product costing several hundred euros, a single drop caught in time can cover the cost of the tool. We run the numbers, with examples, in is a price tracker subscription worth it?
4. You're done reading charts: an indicator and an alert tell you when to act.

How much does a paid price tracker cost?

Prices vary a lot depending on who the tool is for. Keepa Pro, built mainly for Amazon sellers and advanced data, is listed at €29 a month on Keepa's website. UniverTrack's plans, built for shoppers, range from €3.99 a month (Découverte, up to 10 products) to €19.99 a month (Expert, unlimited products), with 2 months free on annual billing. Full details are on the pricing page. For a point-by-point comparison, see UniverTrack vs Keepa.

Try a paid tracker risk-free: the free trial

The best way to decide is to test it on a real purchase. Every UniverTrack plan starts with a 14-day free trial, with no commitment. A payment method is requested at sign-up, but if you cancel from your Account page before the trial ends, the paid subscription does not start. Two weeks is often enough to see whether the alerts save you time, and whether the tool spots drops you would have missed.

Put it into practice: choose and test in 10 minutes

1. Paste the link of the product you plan to buy (Amazon, Cdiscount or another online store).
2. Set a realistic target price, based on the history and the "good time to buy" indicator.
3. Get the email alert and buy when the price is genuinely good, or let it pass.

For a single big purchase, the Découverte plan is enough. If you hunt deals across many products or worry about fake discounts, Malin is the better fit; if you compare the same product across several retailers, look at Pro. Compare plans on the pricing page, then start your 14-day free trial.
