Knockoff Extension Filters Out No-Name Brands on Amazon
A Chrome and Firefox extension called Knockoff cross-references Amazon listings against a 5,000-brand registry to gray out or hide shady, unbranded items. It offers Relaxed, Standard, and Strict modes, plus allowlists and blocklists, and runs locally without logging in or tracking. The article notes not all unknown brands are bad (Xteink is given as an example) and advises readers to check reviews, seller profiles, price history, and specs even when items are filtered.
