Soldometer : See how much any Amazon listing sells,right on the page

Hey Product Hunt 👋

I'm Brent — I sell and flip products on Amazon myself, and Soldometer is the tool I kept wishing existed.

Every buying decision starts with the same question: "is this listing actually selling?" Answering it usually meant guessing from the Best Sellers Rank, or paying for heavyweight research software built for big operations. I wanted something lighter and more honest: open a listing, see a sales estimate, decide.

So I built Soldometer. It's a Chrome extension that estimates any listing's monthly units and revenue, right on the Amazon page. The headline number is anchored on Amazon's own "bought in past month" badge — the closest thing to ground truth Amazon shows publicly — with a rank model as backup when there's no badge. It also adds estimates to listings as you browse search results, shows who holds the Buy Box, and runs a quick profit check against your own price and margin targets.

One thing I care about: Amazon doesn't publish exact competitor sales, so I don't pretend otherwise. Everything is labelled an estimate, and the site explains how they're derived.

It's free to install, and the first 1,000 members are Founding Members — free forever. No card; you just claim a spot with an email.

Feedback that would help most:

• If you sell on Amazon — do the estimates look right on products whose sales you actually know?

• Is the email activation step a fair trade for free-forever, or a dealbreaker?

• What's the first thing you'd want it to do that it doesn't?

Thanks for taking a look — I'll be here all launch day answering everything.
