The browser that works for you, not against you.
Omni Browser is a private, fast and powerful open-source Android browser built on Mozilla’s GeckoView engine — with a stream sniffer, encrypted vault, Firefox extensions and zero telemetry.
Everything a power user wants. Nothing they don’t.
Omni packs a desktop-class feature set into a native Android app — without the tracking, the bloat or the paywalls.
