Choose your path

Cua Spaces: Install the app and run your first Space.
Cua Driver: Operate Calculator and verify its result.
Lume: Create a Tahoe VM and connect over SSH.
Cua SDK and CLI: Install cua and create a local sandbox.
CUA-S1: Explore small, specialized models for computer-use decisions.
Cua Bench: Create and verify a simulated task.

Bring your own agent and model, or explore CUA-S1 for specialized decisions. Cua provides the computer and automation tools. Computer-Use 2.0 describes an agent moving between code, APIs, and graphical interfaces within the same task.

Cua Spaces

Cua Spaces is a desktop app that gives your agents full desktops. Each desktop is a Space: a macOS VM built locally on your Mac, or a Linux or Omarchy image. Spaces run on your Mac, on other machines you own, and in your own cloud account (AWS, Google Cloud or Modal), and the app keeps them in your menu bar and notch.

Teleport. Move a signed-in app, such as Chrome or Slack, into a Space and it opens there still signed in. Your sessions stay in the Cua Keyvault, encrypted on your Mac, and reach a Space only after you approve.
Multiplayer. You and your agents work on the same desktop, each with your own cursor. Step in to make a choice, then hand the desktop back.
Agent-ready images. Spaces images ship with cua-spacesd, so agents get processes, files, screenshots and input as soon as a Space starts.

Install on macOS 26 or later

curl -fsSL https://cua.ai/install.sh | sh

On macOS the installer selects the Cua Spaces app by default and adds the cua CLI. You can also download the signed .dmg, or get the .pkg from the Cua Spaces 0.1.0 release.

Spaces is free for individuals. Pro and Teams plans are coming soon. The app is source-available under FSL-1.1-MIT.

Cua Driver

Give your agent tools to inspect and operate native desktop apps and browsers on macOS, Windows, and Linux. Connect through the CLI, MCP, or typed SDKs. Background delivery lets agents work without moving your pointer or taking focus when the app and platform support it; see platform support for the boundaries.

macOS / Linux

/bin/bash -c "$(curl -fsSL https://cua.ai/driver/install.sh)"

Windows (PowerShell)

irm https://cua.ai/driver/install.ps1 | iex

Your first result: connect your agent, ask it to compute 6 × 7 in Calculator, and have it verify that the app displays 42. The tutorial covers platform setup, permissions, and agent connection.

Two Cua Driver sessions select cells in LibreOffice Calc and objects in Inkscape on an Omarchy desktop while a terminal stays in the foreground. Watch the 50-second demo.

Lume

Create and manage local macOS and Linux VMs on Apple Silicon using Apple's Virtualization.Framework.

/bin/bash -c "$(curl -fsSL https://cua.ai/lume/install.sh)"

Your first result: create a vanilla macOS Tahoe VM from an Apple restore image, start it, and connect over SSH. The tutorial uses the Lume CLI directly and explains the unattended setup defaults.

Create your first Lume VM | Installation | CLI reference

Cua SDK and CLI

One SDK and one cua command for local VMs and containers, and for any machine that runs cua-spacesd.

macOS / Linux

curl -fsSL https://cua.ai/install.sh | sh

Windows (PowerShell)

irm https://cua.ai/install.ps1 | iex

In a terminal the script shows a short checklist: the cua CLI, the Cua Spaces app (default on macOS), the cua-driver MCP and skill for your agents, and hosting this machine. It then runs cua auth login, which signs you in and offers to install cua skills and the cua MCP server into your AI coding agents (Claude Code, Codex, Cursor, and others). Preselect items with sh -s -- --select cua-driver, or skip the checklist with --only cua-driver. See the installer options.

cua sb create ubuntu --name dev          # a gVisor container, set up on first use
cua sb exec dev uname -a
cua sb screenshot dev
cua sb rm dev

The same sandbox from Python:

from cua_sandbox import Image, Sandbox

async with Sandbox.ephemeral(Image.linux(), local=True) as sb:
    print((await sb.shell.run("uname -a")).stdout)

SDK: the same API in Python (pip install cua), TypeScript (@trycua/cua), Swift (Cua) and Kotlin (generated bindings), running embedded in your process or through a shared cua daemon.
Sandboxes need no agent inside. Readiness comes from the runtime and optional port probes. Images that ship cua-spacesd (port 3211) add processes, files, screenshots, input through cua-driver, and low-latency video and audio streaming.
Your own machines. cua host setup makes this machine reachable through the cua.ai relay with no port forwarding.
