Any OS. Any agent. Self-hostable.

Cua is an open-source platform for building, benchmarking, and deploying agents that can use any computer, with isolated, self-hostable sandboxes (Docker, QEMU, Apple Vz).

Cua - Agentic UI Automation & Code Execution

Build agents that see screens, click buttons, and complete tasks autonomously. Run isolated code execution environments for AI coding assistants like Claude Code, Codex CLI, or OpenCode.

# Requires Python 3.12 or 3.13
from computer import Computer
from agent import ComputerAgent

computer = Computer(os_type="linux", provider_type="cloud")
agent = ComputerAgent(model="anthropic/claude-sonnet-4-5-20250929", computer=computer)

async for result in agent.run([{"role": "user", "content": "Open Firefox and search for Cua"}]):
    print(result)

Cua-Bench - Benchmarks & RL Environments

Evaluate computer-use agents on OSWorld, ScreenSpot, Windows Arena, and custom tasks. Export trajectories for training.

# Install and create base image
cd cua-bench
uv tool install -e . && cb image create linux-docker

# Run benchmark with agent
cb run dataset datasets/cua-bench-basic --agent cua-agent --max-parallel 4
