Browser Use

  • The library is free; models and cloud browsers cost money
  • Telemetry is on by default and can include task text and addresses
  • Reusing your real Chrome profile can mean quitting Chrome first

Codex

  • In the desktop app only: not in Codex CLI or the IDE extension
  • Computer use is limited by region and missing on Linux
  • Its own browser uses a separate profile and can’t upload files for you
  • No MCP server for other agents

Yab, honestly

  • Mac only: macOS 15.4 or later, no Windows, iPhone or Android
  • New: first released in September 2026
  • Its AI needs a Claude or ChatGPT plan; ChatGPT’s free plan may work with low limits
  • WebKit, as in Safari: a site tested only in Chrome can misbehave
  • Closed source
