Chromium is downloaded automatically when you use Render mode. No separate installation needed.

Supported platforms for Chromium:

The first Render mode call downloads Chromium (~160MB) to ~/.b4n1web/chromium/. Subsequent calls reuse it.

# Add to PATH
export PATH="$HOME/.local/bin:$PATH"
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc

chmod +x ~/.local/bin/b4n1web

Check internet connection. Chromium is downloaded from Google’s storage. For offline environments, pre-download and place in ~/.b4n1web/chromium/.

Ensure you’re using the correct binary for your platform:

uname -m  # x86_64 or aarch64
