Helium DRM Fixer

A CLI tool that fixes DRM issues in the Helium browser by copying WidevineCdm from Chrome (or other Chrome-based browsers).

Why Helium DRM?

Helium browser often has issues with DRM-protected content because it doesn't include WidevineCdm. This tool automatically copies WidevineCdm from your Chrome installation to Helium, enabling basic Widevine support for sites that accept it.

Installation

bun install

Usage

bun run cli.ts

Or after building:

bun run build
./dist/fix-helium-drm

How It Works

1. Finds Chrome WidevineCdm: The tool searches for your Chrome (or other Chromium-based browser) installation and locates the WidevineCdm directory.
2. Finds Helium installation: Locates your Helium browser installation.
3. Copies WidevineCdm: Copies the WidevineCdm files from Chrome to Helium.
4. Automatic download: If Chrome is not found locally, the tool will download it from GitHub releases (Windows only).

Limitations

This tool only makes Helium able to load Widevine. It does not change Helium's Chromium build, browser identity, codecs, HDCP support, Widevine certification, or Verified Media Path status.

That is why DRM can work on some sites, such as YouTube or Crunchyroll, but still fail on stricter services such as Netflix or Amazon Prime Video. Those services can require an approved browser, output protection, VMP, or other license-server checks that copying WidevineCdm cannot satisfy.

Features

• Automatic Chrome/Helium detection
• Automatic Chrome download if not found (Windows only)
• Download caching with checksum verification
• Progress tracking for downloads
• Cross-platform support (Windows, macOS, Linux)
• Type-safe TypeScript implementation

Custom paths

If this script fails to find your browser, you can specify the path to it manually:

sudo bun run cli.ts --chrome-path /usr/bin/google-chrome-stable --helium-path /usr/bin/helium-browser

You can find the path on your system by running which google-chrome-stable on macOS and Linux.

Development

# Run tests
bun test

# Lint code
bun run lint

# Auto-fix lint issues

Troubleshooting

"Helium browser not found"

Ensure you have Helium browser installed. Download it from https://helium.is/.

"Chrome not found"

The tool will automatically download Chrome. If this fails, install Chrome manually from https://www.google.com/chrome/.

"Failed to copy WidevineCdm"

Make sure you have write permissions to the Helium application directory.
