We build privacy-focused browsers that do not track your behavior, collect your data, or monetize your attention.
Echo Technology stands for transparency, simplicity, and user control — without compromise.
To create software that respects people — not treats them as products.
A clean, fast, and honest web experience, even on older or low-power hardware.
Echo Technology builds Surf Browser on top of ungoogled-chromium — an open-source Chromium base without Google services.
Our focus is not on deep source-level patching, but on careful configuration, sane defaults, and predictable browser behavior.
Surf Browser is optimized for reduced background activity, lower resource usage, and strong compatibility with modern websites — without added telemetry, advertising frameworks, or hidden online services.
We believe privacy should be practical. That is why Surf Browser avoids extreme changes that break websites or user workflows.
* Chromium and ungoogled-chromium are independent open-source projects used as technical foundations. Echo Technology does not control upstream development and focuses on transparent configuration, distribution, and user experience.
Search is a core part of everyday browsing. That is why Surf Browser uses a privacy-respecting search engine by default.
Surf Browser uses Presearch as its default search engine.
Private search powered by Presearch
Presearch is a decentralized search platform focused on privacy and transparency. It does not build personal profiles or sell behavioral data.
Presearch is a third-party service. Echo Technology is an independent project and is not owned or operated by Presearch.
