Ecosia Browser is a free web browser developed by Ecosia GmbH (Berlin) emphasizing user privacy and sustainability. It includes a privacy panel that warns of unsafe sites and can auto-adjust cookie settings, as well as blocking trackers and ads by default. The browser integrates the Ecosia search engine (which uses ad revenue to fund tree planting) directly into the address bar. Ecosia Browser is also optimized for performance and energy efficiency, claiming faster page loads and reduced battery use than mainstream browsers. It is open-source, B-Corp certified, and designed as part of Ecosia’s mission to create a “better web” for users and the planet.
