Installation
Summary

Browser automation with persistent page state across sequential scripts.

  • Two modes: standalone Chromium (default) or extension mode connecting to user's existing Chrome browser with authentication already in place
  • Discover page elements via ARIA snapshot accessibility tree, then interact using element references; alternatively read source code to write direct selectors
  • Small, focused scripts that run incrementally—each script does one action (navigate, click, fill, check), then you evaluate state and decide next steps
  • Built on Playwright Page API with helpers for waiting (page load, selectors, URLs), screenshots, and error recovery through persistent page state
