🔒 Security Considerations
- Secrets: AES-256 encrypted, never logged in plaintext, only keys logged
- Environment: Sensitive env vars masked in info display
- WebDriver: Runs locally by default, configure remote carefully
- CORS: Restricted to dashboard origins by default
- File Uploads: Limited to 50MB, disabled by default
- Rate Limiting: Built-in 429 handling, implement upstream if needed
- Redaction: Frame redaction for recording privacy
- Session Isolation: Each browser/db session is isolated

- Platform Services: The node-windows/node-linux/node-mac packages are platform-specific and marked as optional dependencies.
- Browser Requirements: Chrome/Chromium required for browser automation features.
🛠️ Troubleshooting
Common Issues
Server fails to start
- Check Node.js version (18+ required, 20+ recommended)
- Verify port is not in use:
lsof -ti:3000
- Check environment variables in
.env
Browser automation fails
- Install Chrome/Chromium
- Check if running in headless mode
- Verify WEB_DRIVER_REMOTE_URL if using remote
Dashboard not loading
- Build dashboard:
cd dashboard && npm run build

dashboard/dist/
- Verify CORS settings
Tools not appearing
- Check server logs for registration errors
- Verify sessions are being created properly

/tools
endpoint to debug
WebSocket connection fails
- Check firewall settings
- Verify WebSocket is enabled in config
- Test with simple WebSocket client
Service installation fails
- Windows: Run PowerShell/Command Prompt as Administrator
