bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal

  • Natural Language Commands: Execute browser actions like clicking buttons or extracting data using plain English instructions.
  • AI Integration: Supports state-of-the-art models from OpenAI and Anthropic for advanced automation tasks.
  • Flexible Automation: Choose between traditional code and AI-driven commands based on the task’s complexity.

under the hood

  • Built on TypeScript and fully compatible with Playwright.
  • Provides three primary APIs: act, extract, and observe for streamlined automation.
  • Supports both local and remote browser sessions, with optional integration into Browserbase’s infrastructure.
