How it works

Three steps, zero effort

Vigilante runs quietly in your browser. You shop the way you always do — it does the rest.

01

You shop normally

Browse any online store. Vigilante watches the product page in the background — privately, on your device.

02

It spots the markup

Using product images and identifiers, Vigilante recognizes when an item is dropshipped or resold above its source price.

03

You buy direct

It shows the original source listing and the real price, so you can decide to buy from the source and save.

The markup, measured

Same lamp. Two prices.

A real match from our pipeline: a sunset projection lamp sold on a dropship storefront for $39.95 — and listed by its source seller for $8.74. Most of the sticker price is markup.

Why Vigilante

Built to be trustworthy

We only show a source when we're confident it's the same product — and we're upfront about how we make money.

Verified matches only

Source links are based on shared product images and identifiers — not guesswork — so you see real matches, not look-alikes.

Private by design

It sends two things: the page address and the product's barcode number. Not the price you're paying, not your cart, not your card, not the rest of your browsing. Open your network tab and check — that's the whole request.

Right at the moment

Vigilante checks the moment a product page loads — and again at cart and checkout. One look as the page settles, then it's out of the way unless something's wrong.

How we make money — openly

When you buy through some of the source links Vigilante surfaces — including AliExpress affiliate links — we may earn a small commission. This never changes the price you pay, and we only show a source we believe is genuinely cheaper. Every recommendation discloses the affiliate relationship right on the card. That's the whole model: we win when you save.

Stop overpaying for dropshipped products

Add to Chrome — it's free

What Chrome will ask you

Installing shows a permission prompt about reading site data — every shopping extension needs it. Vigilante only reads the product details on checkout pages: title, price, product code, image. It never runs on banks, email, or anything that isn't a store. Nothing about you is ever sent anywhere.
