Vanadium Browser — Hardened Chromium for GrapheneOS (2026)

Vanadium is the default privacy-hardened browser on GrapheneOS. Built on Chromium with enhanced security, no telemetry, and strict site isolation.

What is Vanadium?

What Is Vanadium?

Vanadium is the default web browser included with GrapheneOS, the privacy-focused Android operating system. Built on Chromium, Vanadium strips out Google services and telemetry while adding hardened security features that go beyond what stock Chromium or Chrome offer.

Key Features

Vanadium includes hardened memory allocator integration, stricter site isolation, and reduced attack surface compared to standard Chromium. It blocks third-party cookies by default, disables JavaScript JIT compilation for security (with an option to re-enable it per-site), and uses a hardened WebView implementation.

The browser is intentionally minimal — no sync features, no account integration, no telemetry. This is by design, as GrapheneOS prioritizes security and privacy over convenience features.

Who Uses Vanadium

Vanadium is primarily used by GrapheneOS users who want a browser that matches their OS-level privacy stance. It appeals to security researchers, privacy advocates, and anyone who wants the most hardened Chromium-based browser available on Android.

Limitations

Vanadium is only available on GrapheneOS — you cannot install it on standard Android. It lacks extension support, sync features, and many convenience features found in browsers like Brave or Firefox. The strict security defaults can break some websites.
