Stop buying into dead listings.
Will it sell? Is it saturated? Will I make money?
Every other tool hands you the same list as 43 other people, then stays silent on the one thing that kills the deal.
You find a product, the margin looks great, you buy 200 units, and by the time they land, eight more sellers have piled on and the price has tanked. Numbers alone never told you the window was already closing. SatScore does.
Live in under a minute
No setup, no spreadsheet. Three steps and the numbers follow you around Amazon.

Real fees, real margin, real break-even on every product page. Exact Amazon fees when you link your seller account. No spreadsheet.
SatScore saturation gauge
A 0-100 score: FRESH, WARMING, HOT or COOKED. Know whether the gold rush is still open or already over before you commit.
BUY / RISKY / SKIP verdict
One color-coded call that folds profit, eligibility, saturation, hazmat and Amazon-on-the-listing into a single glance.
Risk signals built in
Hazmat, oversize, sales velocity, buy-box lock and 'is Amazon competing', flagged before you spend a cent.
Stalk any seller
One click puts a competitor's whole storefront under surveillance, so you see what they source next, pushed to Discord, Slack or Telegram.
Export to your lead bank
Save a deal to Arbitrage Stalker with cost and source URL in one click, then track it from found to sold.
The thing no other extension has
SatScore: is this product fresh, or already cooked?
One 0-100 score, computed from FBA seller count, offer-count velocity, buy-box price trend and demand stability. It tells you how much profitable runway is left before the crowd floods the listing. That is the exact failure that wrecks most online-arbitrage buys.
And it doesn't stop at one product. On Amazon search and storefront pages, every tile gets a SatScore badge, so you spot the fresh lanes before you open a single listing.
Lots of profitable runway left. Few sellers, stable price, healthy demand. Move before the crowd shows up.
A price, a rank, a guess.
Profit, saturation and the verdict, instantly.
Sellers are already finding leads with it.
Unprompted, on live calls. Real Amazon sellers in the community, in their own words.
I've been using Arbitrage Stalker a lot lately. I got one storefront in there and, oh my god, it's just a gold mine.
I've used Arbitrage Stalker with a retail monitor and found a couple of items I hadn't looked at before. There were some nice leads. So I'm happy.

Questions, answered
Is it actually free?+
Yes. Free to install, and it runs on a free Arbitrage Stalker account with no card. The on-page profit, fees, SatScore and the buy/skip verdict cost you nothing, and verifying your email gets you 1 AI APEX Read to try, free. Link your Amazon account and the free Reads become 3 every month. Unlimited reads, storefront stalking and crowd alerts live on the paid plans.
Do I need an account?+
A free account, yes. It takes about ten seconds the first time you open the extension, no card. It powers the live SatScore, your lead banks and the verdict.
Why link my Amazon account?+
Two reasons. It pulls your exact Amazon fees instead of estimates, and it unlocks 3 free AI APEX Reads a month. It also keeps the free AI fair: one Seller account gets one free allowance, so nobody farms endless free reads with throwaway logins. It is a standard SP-API connection you authorize and can revoke any time.
What is the AI APEX Read?+
A one-tap AI verdict on any product: is it a buy, and what could kill it. It reads the price history, saturation, competition and risk signals, then gives you the call in plain English. You get 1 free to try when you verify your email, then 3 a month once you link Amazon. Paid plans run from 100 to 1,200 a month.
What data does it read?+
Only Amazon product and search pages, exactly what any shopper sees. It never reads your passwords, payment info, or any other tab. Linking your Seller account for exact fees is a standard SP-API connection you authorize and can revoke any time.
Does it slow Amazon down?+
No. It's a lightweight Manifest V3 extension that injects a single panel and gets out of the way. It dims itself when Amazon opens its own popovers so it never fights for your attention.
Which marketplaces does it work on?+
Amazon US, CA, UK, DE, FR, ES, IT, MX, JP and AU.
How is this different from SellerAmp?+
They show you data and margin math, and their trial wants a card up front. Arbitrage Stalker is free to run, scores saturation (the SatScore), gives you a buy/skip verdict, and puts any competitor's storefront under live surveillance. You get the numbers, plus whether the window is still open and who else is circling.
