Install

Extension

1. Clone this repo or download the source
2. Open chrome://extensions in Chrome/Chromium
3. Enable Developer mode (top right)

5. Click the ⚡ icon in your toolbar

Native Host (optional)

Requires Node.js (v16+).

Linux / macOS:

cd native-host

# Install without extension ID (update later):
./install.sh

# Or install with your extension ID:
./install.sh --extension-id=your-extension-id-here

# Uninstall:
./install.sh --uninstall

Windows (PowerShell):

cd native-host

# Install without extension ID (update later):
.\install.ps1

# Or install with your extension ID:
.\install.ps1 -ExtensionId your-extension-id-here

# Uninstall:
.\install.ps1 -Uninstall

To find your extension ID: go to chrome://extensions, find WebStat, copy the ID.

After installing, restart Chrome/Edge. The extension will automatically detect the native host and show enhanced monitoring data.

How It Works

Extension only: Uses Chrome's built-in system.cpu, system.memory, and system.storage APIs. No network requests, no external dependencies, no data leaves your machine.

Enhanced mode: The extension connects to a local Node.js process via Chrome Native Messaging. The host process reads system data from /proc (Linux), ps/df (macOS), or wmic (Windows) and sends it to the extension over stdio. No network, no ports, no servers.

Privacy

• Zero network requests
• Zero analytics or tracking
• Zero data collection
• All data stays on your machine
• Open source — read every line

Compatibility

• Chrome 91+ / Chromium 91+
• Native host: Linux, macOS, Windows (PowerShell installer + Edge support)
• Firefox: Not yet supported (different extension API)
