Iridium Browser is a privacy-focused browser based on Chromium, developed as a software project of Red Cool Beans UG. The project describes it as a browser that prevents partial queries, keywords and metrics from being sent to central services unless the user approves. Iridium is distributed only as source-code tarballs, so organisations compile and run it on their own computers, and its changes are visible in a public Git repository.
Red Cool Beans UG is a German company, so the operator is established in the EU. The vendor's site does not describe a cloud service for browsing, so the browser keeps its data on the user's own device. The vendor does not name a licence, so the product is not presented as open source. For a European organisation, Iridium is an EU-operated, locally run Chromium variant that can be audited through its public source code, though its support level and release cadence should be assessed before deployment.
