Non-European but Open Source

The Open Source category highlights projects that, while originally developed in countries outside of Europe, allow anyone from around the world to contribute. These projects are not bound by geographic location—anyone, regardless of where they are based, can review, modify, and improve the code. The key factor is that the source code is available for anyone to examine, ensuring that the product can be independently verified and trusted, regardless of its origin. By featuring open-source projects, we promote transparency, collaboration, and innovation on a global scale.

Submit Suggestion

European web browsers are rarer than European search engines, but there are real options: Vivaldi and Opera from Norway, Mullvad Browser from Sweden, Ecosia Browser from Germany and community builds such as LibreWolf. Firefox is also listed as an open-source alternative that anyone can fork and self-build.

Privacy-focused browsers

Mullvad Browser is developed together with the Tor Project and aims to minimise tracking and fingerprints; it is open source, free of charge and runs on Linux, macOS and Windows.[1] LibreWolf is an independent, largely community-driven version of Firefox built from the latest Firefox stable source, with telemetry removed.[2] Firefox itself presents itself as an independent browser that blocks trackers.[3]

Feature-rich and everyday browsers

Vivaldi describes itself as an independent browser company based in Norway and Iceland.[4] It ships a built-in ad blocker, mail client, calendar, feed reader, tab stacks and page translation.[5] Opera was born in Oslo, which is still its home base.[6] Ecosia Browser funds tree planting and renewable energy.[7]

What to keep in mind

Most of these browsers are built on a Chromium or Firefox engine from outside Europe, so the benefit lies in the company, its data practices and its features rather than in a separate European engine. Check each product page for ownership and open-source status before you switch.
