When to choose:
  • You want a visual GUI agent that understands native desktop screens and operates mouse/keyboard actions end-to-end via vision models.
  • You want an open-source multimodal desktop application for cross-application task automation on macOS, Windows, and Linux.
When to skip:
  • You only need web-browser-based automation; Playwright or Scrapling are much faster and more reliable via direct DOM.
  • Your environment lacks a capable GPU or reliable multimodal LLM API with high vision resolution support.
