vercel-labs/agent-browser v0.21.0

on GitHub

Minor Changes

• c6de80b: ### New Features

  • batch command -- Execute multiple commands from stdin in a single invocation. Accepts a JSON array of string arrays and returns results sequentially. Supports --bail to stop on first error and --json for structured output (#865)
  • iframe support -- CLI interactions and snapshots now traverse into iframe content, enabling automation of cross-frame pages (#869)
  • network har start/stop command -- Capture and export network traffic in HAR 1.2 format (#874)
  • WebSocket fallback for CDP discovery -- When HTTP-based CDP endpoint discovery fails, the CLI now falls back to a WebSocket connection automatically (#873)

  Improvements

  • --full/-f refactored to command-level flag -- Moved from a global flag to a per-command flag for clearer scoping (#877)
  • Enhanced Chrome launch -- Added --user-data-dir support and configurable launch timeout for more reliable browser startup (#852)

  Bug Fixes

  • Fixed /json/list fallback when /json/version endpoint is unavailable, improving compatibility with non-standard CDP implementations (#861)
  • Fixed daemon liveness detection for PID namespace isolation (e.g. unshare). Uses socket connectivity as the sole liveness check instead of kill(pid, 0), which fails when the caller cannot see the daemon's PID (#879)
  • Fixed Ubuntu dependency install accidentally removing system packages (#884)
