GoKawiilIf you're an Amazon shopper, you've likely noticed fake brands flooding the website in recent years. A new extension made by developer Josh Pigford promises to hide the phony, cheaply made products and lets you shop like a normal person again.
The extension, called Knockoff, is available for Firefox, Chrome and all Chromium-based web browsers such as Microsoft Edge, Opera and Brave. Since Pigford launched the extension on Tuesday, it's gone viral, with tens of thousands of downloads. A few days before this week's launch, Pigford posted on X, "Built a little chrome extension that lets you dim (or hide!) all the crap, mass-produced, fake brands on Amazon." The post garnered 22,000 likes.
Knockoff is now live!
Filter out the knockoff crap brands on Amazon.
Sorry to brands like WNPETHOME, EHEYCIGA, YXYL, LU&MN, JOYIN, TOMY, GODONLIF, YOOJEE, LINGTENG, LANEIGE, VISCOO, BIODANCE, COOFANDY, BALENNZ, TOSY and LUENX.https://t.co/9mLk0EAsfG https://t.co/K07lMkepOW — Josh Pigford (@Shpigford) July 7, 2026
It works pretty simply. Once installed, any products from fake brands, dropshippers or otherwise suspicious vendors are marked and grayed out, highlighting the more reputable brands you might actually know. There's also an option to automatically hide the fake brands so you don't even have to see them at all.
In an interview with 404 Media, Pigford says that Knockoff is built on prior extensions that aim to do this, such as AmazonBrandFilter and Amazon Brand Detector. The extension, which runs locally, doesn't require an account, doesn't send data to any company servers and doesn't cost anything. It's also open source, and you can find the source code on GitHub.
The extension's functions are pretty simple to understand. If it's grayed out, it's likely a fake brand, but the extension does need some fine-tuning. Joe Hindy/CNET
