Developed by Ecosia GmbH (a B-Corp known for its tree-planting search engine), Ecosia Browser is based on the Chromium engine and includes Ecosia’s search bar by default. It emphasizes sustainability and privacy: it advertises “the world’s greenest AI” and includes a dashboard for tracking the number of trees planted via searches. The browser is optimized for performance and energy efficiency (claiming faster page loads and a battery-saving mode). Built-in privacy features include a privacy panel that warns users about unsafe websites and offers controls over cookie and tracking settings. Ecosia Browser also offers automatic HTTPS upgrades. As an example, the site notes it has no vendor-lockin (open source) and its parent company donates most of its profits to reforestation projects. The browser is available on desktop and mobile platforms for consumers who want a combination of privacy and environmental benefits.
