Private Price comparison while you shop
Same item.
Lower price.
Nobody watching.
FairRobin is a price comparison extension. On a product page it finds the same item at other stores, puts exact matches first, then shows the price you would pay. No store pays for a higher spot. Comparing the page is free. A discount code appears only when a real one is printed on the page. If you are not ready to buy, it keeps an eye on the price for you.

What you could save
$830a year
You could save about $830 a year just by buying the same things from the store that charges less. The exact same item often costs more at one store than another, and most people never check.
18.8%
Usually, the exact same item cost about 19% more at one store than at another nearby.
Aparicio, Metzman & Rigobon, 2023
57%
For the same gadget online, the most expensive store charged 57% more than the cheapest one, on average.

You could save every year
$830
How we got $830: 18.8% of $4,415. It's an estimate from the public research above, not a number from FairRobin users. We don't track what you buy, so we can't see what you save. What you actually save depends on what you shop for and whether another store has it for less.
How it works
It works off to the side.
It works off to the side.
You keep shopping.
FairRobin never moves the buy button, takes over the page, or opens tabs in front of you. The lookups happen in the background.
See what you'd save
It checks Google, Amazon, Walmart, and Bing Shopping for the same item and tells you right away, like “You'd save $38 at Store B.” Only prices it actually saw are shown. A coupon appears only when a real code is on the page.
Hear when it drops
Choose “Tell me if it gets cheaper.” FairRobin rechecks every couple of hours and shows a Chrome notice when the price is lower.
An unbiased view
Ranked by price.
Ranked by price.
Not by who pays.
Lots of shopping tools earn money from the stores they send you to, so it's hard to tell whether a result is the best deal or just the best paying one. No store pays FairRobin, and we earn nothing when you click. Your subscription is our only income, so our only job is to show you the price.
- No paid placement. No store can buy a higher spot on the card.
- One rule for the order. Exact matches come first, then the lowest price you'd actually pay.
- We tell you to stay when it's best. If the page you're on is cheapest, the card says so.
- Clean links. No affiliate tags or cashback cookies, and tracking tags are removed.

Inside FairRobin
The parts you'll
The parts you'll
actually see.
These are layouts from the extension, with example items.
Every price you've checked, in one place.
Drops are highlighted in orange. Stop alerts, open the store, or remove an item, and the list tells you right away what happened.
One click from anywhere.
The toolbar icon counts the drops you haven't opened yet. Click it to bring the card back or open Your list.
A notice when it's cheaper.
It's an ordinary Chrome notice on this computer. There's no email, and we don't need your phone number.
The whole point
Checking a price shouldn't build a profile of you.
Most shopping tools pay for themselves by learning what you buy. FairRobin is built the other way around. The product, the price, and your list stay in this browser. A small model shipped inside the extension reads the page right on this computer.
- No account. Nothing to sign up for or log in to.
- Nothing you shop for is sent to FairRobin. It isn't sold or used for ads.
- No affiliate links. Tracking tags are removed from store links, and we aren't paid if you click.
- Your cart, email, and payment details are left alone. FairRobin only reads the product on the page.
- Site visits are measured. Google Analytics records the page and how someone arrived. No ad pixels, and no web fonts loaded from anyone else.

about the price.
What FairRobin does, in the same words as the product.
Price comparison app
FairRobin is a price comparison extension. On a product page it finds the same item at other stores, puts exact matches first, then shows the price you would pay. No store pays for a higher spot. Comparing the page is free.
Best price tracker without affiliate links
FairRobin does not use affiliate links. No store pays for a higher spot, and comparing the page is free.
How to know if a price is actually a deal
A price is a deal when the same item costs less somewhere else right now. A crossed-out number on the page is not proof.
Price history
The prices you ask FairRobin to remember stay on this computer. This site does not publish a catalog of other people's prices.
How price drop alerts work
You choose a price to watch. FairRobin rechecks it about every two hours on this computer and notifies you if it drops.
How to check a Black Friday price
A percent-off badge is not proof. Compare the same item at other stores, with exact matches first.
Compare the same product at other stores
Start from the page you already opened. Exact matches come first, then the price you would pay.
When this page is already the cheapest
If no other exact match costs less, FairRobin says so. Staying on this page is the result.
Sponsored listings and price comparison
A store's own sponsored listings stay in the list and are ranked by price. No store can buy a higher spot.
Watch a price without an account
The title, page, and price stay on this computer. Three watches are free.
Used and new are not the same price
A maybe-used mark comes from words on the listing. It is a hint, not a promise.
Shipping and tax in a price comparison
The card shows the item price. Shipping is unknown unless the store shows it. Tax is an estimate after a ZIP.
A lookalike is not the same item
A similar model, size, or pack count is marked. Exact matches come first.
When a discount code is real
A code appears only when the page prints the code and the amount. FairRobin does not invent coupons.
A price comparison that stays on your computer
The product, the price, and your list stay here. They are not sent, sold, or used for ads.
