Infinity Browser

What is Infinity Browser?

Infinity Browser is a platform that lets companies launch and operate their own branded, first-party web browser. It covers building and customising the browser, distribution and growth, monetisation and engagement, browser services and infrastructure, and AI-native capabilities such as an in-browser assistant. A related service, Infinity Upstream, takes over Chromium fork maintenance for teams that already ship their own browser, with desktop and Android in production. The company says a first version can be ready in 6 to 8 weeks. Partners named on the site include Ecosia, which built Ecosia Browser on the platform, and the Heart browser. It is aimed at search engines, media brands, fintech and consumer companies that want direct access to user context and revenue from search partnerships, advertising, affiliate deals and premium features. Pricing is not published; the site points visitors to a strategy call to scope the work.
