GitHub·high signal

Cua provides open-source sandboxes, SDKs, and benchmarks for building AI agents that control full desktops across macOS, Linux, Windows, and Android, backed by Y Combinator. The April 2026 cua-driver release lets any coding agent (Claude Code, Codex, custom harnesses) drive native Mac apps in the background without stealing cursor or focus, hitting up to 97% native CPU speed on Apple Silicon. Every session records as a replayable trajectory, with CLI and MCP server support for Claude Code, Cursor, and custom clients.
