class HybridBrowserToolkit(BaseToolkit):
A hybrid browser toolkit that can switch between TypeScript and Python implementations. This wrapper allows users to choose between:
  • ‘typescript’: WebSocket-based implementation using TypeScript/Node.js
  • ‘python’: Pure Python implementation using Playwright directly
