Vanadium

Hardened Chromium fork bundled with GrapheneOS — the most secure Android browser available.

Vanadium is GrapheneOS's custom browser built on Chromium with substantial hardening patches. It strips telemetry, disables Google services, enforces strict site isolation, and compiles with CFI (Control-Flow Integrity). Designed exclusively for GrapheneOS, it leverages OS-level exploit mitigations for defense-in-depth. Unlike other privacy browsers, Vanadium prioritizes security hardening over fingerprinting resistance — making it the browser of choice when you need a Chromium renderer that won't be the weak link in your mobile threat model.

Best for
