Category: library

Tags: macos-automation, computer-use, accessibility-api

Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 7, Utility: 7)

This project provides a local macOS API that mimics OpenAI's Codex Computer Use, enabling agents to control native apps and windows via HTTP without stealing the user's pointer. It combines accessibility and screenshot APIs to dispatch clicks, scrolling, and text input, making multi-window desktop automation possible entirely on-device.

Target audience: backend devs, devops, ai engineers
