Best for
  • Developers experimenting with browser automation.
  • Users who want AI browser capabilities in Chrome, Edge, or Electron.
  • Users who need access to Composio integrations.
  • Frontend developers who want AI-assisted web debugging and performance analysis
  • Scenarios that need browser automation and performance diagnostics in the same tool
Not for
  • Users seeking a documented MCP server transport or standard client configuration.
  • Users unwilling to provide a Google API key.
  • Production environments requiring confirmed official maintenance or a known license.
  • Cases that only need to scrape page text without performance analysis or complex interaction (a lighter scraping tool is a better fit)
Required permissions
  • Requires browser-extension access to perform screenshots, clicks, typing, scrolling, and navigation on web pages.
  • Requires a Google API key; Tool Router mode additionally requires an optional Composio API key.
  • May access user-controlled web content and data from configured integrations.
  • Requires a local Chrome browser instance to run
  • navigate_page can visit any URL; type_text/fill_form and similar tools can enter arbitrary content into the page
Risks and side effects
  • Browser automation may perform sensitive actions; the project provides confirmation dialogs for actions such as checkout and payment.
  • The handling risk for API keys, web content, and integration data depends on configuration and usage.
  • The license is listed as unknown, so specific commercial or redistribution rights should not be assumed.
  • Browser automation tools can access and manipulate the content of open pages — use only in a trusted development/test environment
  • performance_start_trace and similar tracing tools continuously record browser activity — avoid leaving them running on pages containing sensitive information
