Give Every Agent a Cloud Desktop

Built for Claude Code, Codex, OpenClaw, and any computer-use agents.

c/ua is an open-source framework that enables AI agents to control full operating systems within high-performance, lightweight virtual containers. It delivers up to 97% native CPU speed on Apple Silicon and works with any language models.

The Problem

For Computer-Use AI agents to be genuinely useful, they must interact with your system's native applications. But giving full access to your host device is risky - and not ideal. What if the agent's process gets compromised, or the LLM hallucinates and leaks your data? And practically speaking, do you really want to give up control of your entire machine just so the agent can do its job?

In short: How can AI agents interact with operating systems, desktop applications, and browsers without jeopardizing security or sacrificing performance?

Solution: An End-to-End Framework

We combined Apple's Virtualization.Framework with an agent-friendly interface to create:

How It Works

c/ua brings together three powerful components into one unified framework stack:

1. Lume - Our high-performance Virtualization layer leverages Apple's Virtualization.Framework to spin up macOS or Linux environments.

2. Computer-Use Interface (CUI) - This layer lets any process or AI agent - no matter which framework it's built on (like AutoGen, LangGraph, etc.) - see the screen and interact with Lume VMs just like a human would. It supports actions such as clicking, typing, scrolling, and extracting the visual accessibility tree.

3. Computer-Use Agent (CUA) - Built on top of CUI, this general agent framework runs intelligent workflows within these VMs. It's compatible with popular LLM providers like OpenAI, Anthropic, as well as open-source tools like Ollama, LM Studio, and OpenRouter.

An AI agent built with c/ua operates within a virtual environment to:

  • Navigate and interact with any application's interface
  • Read screen content and perform keyboard/mouse actions
  • Switch between applications and self-debug when needed
  • Operate in a secure sandbox with controlled file access

All of this occurs in a fully isolated environment, ensuring your host system, files, and sensitive data remain completely secure - while you continue using your device without interruption.

What Can You Build with c/ua?

c/ua lets AI agents use real desktop apps - just like a human.
