Cua has released an open-source infrastructure for Computer-Use Agents that solves a persistent problem in UI automation. Traditional automation tools take complete control of a user's session, moving cursors, stealing focus, and disrupting workflow. Cua Driver provides a background interface for macOS that lets AI agents interact with applications without interrupting the user's experience, addressing a fundamental challenge in desktop automation.

The project spans multiple components including agent-ready sandboxes for any OS, a cooperative computer-use environment called CuaBot, and benchmarking tools for evaluation. The team overcame macOS API limitations by leveraging SkyLight's SLEventPostToPid to create trusted input events that Chromium accepts without dropping clicks at the renderer boundary, solving a technical hurdle that previously blocked background automation in web applications.

Users have implemented Cua for diverse workflows including demo recording, visual bug reproduction, personal assistant automation, and extracting context from applications without APIs. The project supports various applications from native macOS tools to Chromium-based browsers, CAD software, and design tools, with different interaction strategies tailored to each application type. The MIT-licensed project offers a comprehensive solution for developers building AI agents that need to interact with desktop environments.
