See who owns the products you buy.
Vinegar is a browser extension that shows brand ownership in real-time as you shop, so you always know whose pocket your money goes into.
This product is owned by Nestlé, which you have added to your avoid list.
How It Works
You can browse online retailers exactly as you normally would.
As you do, our extension automatically extracts brand names from product pages and uses that to query our registry-backed, community-supported database for a complete ownership chain.
You can even set up an avoid list to warn you about specific companies.
Your avoid list
When a product connects to a company on your list, we surface a clear warning. The mega conglomerate flag also appears when a major parent company sits in the chain.
This product is owned by Company, which you have added to your avoid list.
Registry-backed & community sourced
These badges tell you whether the chain comes wholly from our registry or also includes community-submitted context you can review.
The ownership chain
We lay out the ownership chain from brand to parent companies, with source links and financial figures where we have them.
We use sources you can check
Where possible, each ownership claim points to a public source. Think Wikipedia, a filing, or a press release. We do this so you can verify it yourself, and everything is as transparent as we can make it.
Your data stays yours
We earn revenue through subscriptions, which pay for the service and unlock extended functionality for Premium users. We will never sell your data or track how you shop past what's necessary to function.
