Palladium

Palladium is a privacy and security hardened variant of Chromium providing the WebView and standard browser for BenzeneOS. It is based on Vanadium from GrapheneOS with additional features and customizations.

Features

In addition to Vanadium's privacy/security hardening:

• Chrome Extension Support - Install extensions from Chrome Web Store
• Kagi Search Engine - Built-in as a search engine option
• Custom Search Engines - Add your own search engines manually (no OpenSearch auto-detection wait)
• Privacy Features - AMP removal, automatic cookie consent acceptance
• Edge Swipe Navigation - Configurable swipe gestures

Building

Prerequisites

• Linux build environment
• depot_tools
• ~100GB disk space

Setup

# Clone this repo
git clone https://github.com/BenzeneOS/Palladium.git
cd Palladium

# Fetch Chromium source (uses depot_tools)
fetch --nohooks chromium
cd src
git checkout 144.0.7559.59  # current stable version
gclient sync --with_branch_heads --with_tags -D

# Apply patches (in order)
cd ..
for patch in patches/*.patch; do
    git -C src am --keep-non-patch "$patch"
done

# Run gclient sync again to apply subproject patches via hooks
