Show HN: Cua Driver — Drive Any macOS App in Background Without Stealing Cursor — 132 Points on HN

GitHub / Hacker News·medium signal

Cua open-sourced an MIT-licensed macOS driver that lets any agent (Claude Code, Codex, custom loops) drive native apps in the background without stealing cursor, focus, or Spaces. Built on SkyLight's private SLEventPostToPid API and yabai's focus-without-raise pattern. Ships vision, AX tree, and SoM capture modalities — AX mode skips Screen Recording entirely. Agent-agnostic via MCP or shell. 132 points, 32 comments.
