Vinegar

Vinegar is a browser extension for online shopping that shows brand ownership chains as a person browses product pages. It is meant to help shoppers see who ultimately owns the products they buy, including when a product traces back to a major parent company.

The extension automatically extracts brand names from product pages and uses them to query a registry-backed, community-supported database. It lays out the ownership chain from brand to parent companies, and it can show source links and financial figures where available. Vinegar also includes avoid lists: when a product connects to a company on the list, it surfaces a clear warning. A separate mega conglomerate flag appears when a major parent company sits in the chain, and the interface can mark whether the chain is registry-backed or includes community-submitted context. The site also says each ownership claim links to public sources such as Wikipedia, filings, or press releases, and that a premium feature will offer independent alternatives, though that feature is marked as coming soon.

Vinegar is delivered as an extension that sits in the browser, and the page says it can be used on online retailers as normally browsed. The pricing shown includes a Free plan at $0 forever or $29.99 per year, with brand ownership lookup on Amazon, verified brand and ultimate parent data, conglomerate revenue flags, avoid lists for up to three companies, source links on every claim, and a revenue highlight for collapsed companies. A Premium plan is listed at $3.49 per month or $29.99 per year and adds multi-platform support for Walmart, Target, and more, a full ownership chain, unlimited avoid lists, and a brand search and history page. The page also identifies the product as being by Convoke LLC and says it is an index rather than an authority.
