What is a Space?
A Space is a full desktop for your agents: a virtual machine or container they can use and you can watch. It runs on your Mac, on computers you own or in your own cloud.
Is it really free?
Yes. Spaces on every computer you connect, Teleport, sharing a Space with named people and the hosted relay up to 2 live sessions and 20 remote hours a month are free. Spaces you reach on your own network don’t use the relay. Spaces in your own cloud are billed by your cloud provider. Pro is $18 a month, and Teams is $30 per seat a month with shared team computers, roles and device approval.
Does Cua host or rent the computers?
No. Spaces run on computers you own or rent yourself: your Mac, other computers you connect, or VMs in your own cloud account. Your cloud provider bills you for those VMs. Cua provides the app, the sharing and the relay that lets your devices reach your computers.
Do I need an account?
No. You can skip sign-in, and Spaces on your Mac or on a computer you add by its address work without an account. Sign in to cua.ai to reach your computers through the relay, share a Space or run Spaces in your own cloud.
What do I need to run it?
A Mac with macOS 26 or later. macOS Spaces are virtual machines that need Apple silicon. Linux Spaces run as containers through Docker or Podman.
Which agents can use a Space?
Claude Code, Codex, Cursor, Gemini CLI, Cline, Kiro and OpenClaw connect through the Cua MCP server, and the installer can set them up for you. Inside a Space, the agent works the desktop's apps through Cua Driver.
How does Teleport keep my apps and sign-ins safe?
Nothing leaves your Mac until you approve it on the consent screen, and macOS asks for Touch ID or your password before cookies and sign-ins are read. The Space checks the bundle's SHA-256 before it opens the app, and on Space images the bundle is sealed end to end to that Space's own key.
What does the relay do, and what can it see?
The relay lets your devices reach your computers without port forwarding, and Spaces on your Mac or reached directly never go through it. It terminates TLS, so it can read the desktop stream, input and files as they pass through, but it doesn't store them. Teleport bundles on Space images are sealed end to end, so for those it forwards only ciphertext.
Does Cua Spaces collect telemetry?
Yes, anonymous usage data is on by default: features used, Space types, durations and error categories, plus the app and OS version and a random install ID that isn't linked to your account. It never includes screen content, file names, URLs, cookies, sign-ins, Teleport bundle contents or prompts, and location lookup from your IP is turned off. Turn it off with the switch in Welcome or Settings, cua telemetry off or DO_NOT_TRACK=1, and it's off in CI unless you turn it on.
Is Cua Spaces open source?
Cua Spaces is source-available under FSL-1.1-MIT: you can use and change it for anything except a competing product, and each release becomes MIT two years after it ships. Cua Driver and Lume are MIT. All of it is in trycua/cua on GitHub. Pro and Teams pay for the hosted service around it: the relay above the free allowance, team computers, roles and device approval, with audit history coming soon.
