brow v1.0.0

Standalone Playwright CLI for agent browser automation. Launches a real Chromium instance with an agent-friendly API — structured commands for common actions, eval escape hatch for full power.

Highlights

  • Ref-based element addressing — snapshot shows [N] refs for interactive elements, click/fill by ref
  • Auto-snapshot on mutations — click, fill, select return updated page state automatically
  • Smart snapshots — table-aware markdown, inline list compression, adaptive node caps
  • Persistent profiles — survive logins across sessions
  • State save/restore — snapshot and restore cookies, localStorage, sessionStorage
  • Parallel tool execution — concurrent tool calls in agent loops
