Teleport moves the whole app.
Teleport packs an app's session (open tabs, profile, sign-ins) into one session bundle and moves it from your Mac into a Space, a full desktop for your agents. Nothing is read until you approve, and sensitive items need Touch ID. The Space checks the bundle's SHA-256 before it opens the app.
On Space images, each bundle is also sealed end to end to that Space's own key, so not even Cua's relay can read the bundle.
How Teleport works
One desktop, a cursor each.
RCDP, Cua's remote desktop protocol, streams each Space to you and handles input separately from the picture, so you and every agent get a cursor of your own on the same desktop. Step in whenever you want to make a call yourself, like choosing the seat, then hand it back.
How streaming works
As many desktops as your computers can hold.
Start a Space on your Mac, on machines you own or in your own cloud, and find them all in one list. Each one streams to you as a live desktop, with low latency over QUIC when your machines are on the same network or can reach each other directly.
This Mac
macOS Spaces are virtual machines built locally with Lume. Linux images run too.
Machines you own
Add the Mac mini on the shelf or the Linux box under the desk.
Ready before your agents move in.
Each Space starts with permissions granted and tools installed, so your agent doesn't stop at a permission dialog. Connect Claude Code, Codex or another agent through the Cua MCP.

Questions, answered.
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 machines you own or in your own cloud.
Is it really free?
Yes, Spaces on your Mac and on machines you own are free, and the hosted relay is free during early access. Spaces in your own cloud are billed by your cloud provider. Pro and Teams are coming soon, with shared team machines, session handoff, keyvault sync and admin controls.
Do I need an account?
No. You can skip sign-in, and Spaces on your Mac or on a machine you add by its address work without an account. Sign in to cua.ai to reach your machines 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 machines 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.
