OpenClaw-ready

Sandboxes work out of the box with OpenClaw and computer-use operator frameworks. Deploy autonomous desktop agents without extra infrastructure — just point your agent at a sandbox and go.

#!/bin/bash

# 1. Boot up an OpenClaw-ready sandbox
cua sb launch ubuntu

# 2. Connect OpenClaw Gateway
cua sb exec curious-fox openclaw start

# 3. Dispatch agent task
cua sb exec curious-fox openclaw agent \
    --model claude-3-5-sonnet \
    --task "Book cheapest flight SFO→MAD"

Capabilities

Built for computer-use agents and more

OpenClaw-ready

Native support for OpenClaw and computer-use operator frameworks. Deploy autonomous desktop agents to sandboxes with zero extra configuration.

Real GUI, not headless

Every sandbox has a full desktop with browser, file manager, and native apps. Your agent sees exactly what a human would see.

Branch and replay

Snapshot a running sandbox. Fork it into parallel sessions. Replay agent trajectories from any checkpoint.

Lightweight or full-OS

Start with lightweight GUI sandboxes for speed, or use full-OS sandboxes when you need a custom kernel and images.

Watch sandboxes live

Stream the desktop to your browser in real time. See what your agent sees, debug visually, intervene when needed.

Sub-minute cold start

Linux sandboxes boot in under 60 seconds. macOS sandboxes are pre-warmed for near-instant allocation. Resume from snapshot in under a second.

Cua Cloud

Cloud desktops for AI agents

Linux, Windows, macOS, Android.

Start building.

Free sandbox minutes included with every account.
