Cua Spaces

Own compute

Shared desktops and programmable sandboxes on your own computers or cloud accounts.

Use Cua directly through its app, SDK or CLI. Sandbox Router does not currently route sandboxes to Cua Spaces.

From Cua Fleet to Cua Spaces

Cua ended its hosted Cloud/Fleets service on 18 October 2026. Spaces is its current offering for computers you supply. Existing links to Cua Fleet in this catalog now lead here.

Where it runs

Your computer, other computers you connect, or your own AWS, Google Cloud, Hetzner or Modal account. You pay the cloud provider for that compute.

Cua runtimes and compute locations ↗

Desktop and code

The SDK exposes screenshots, mouse and keyboard input, a clipboard, shell commands, files and PTY terminals. Spaces can be shared with people and agents.

Sandbox SDK interfaces ↗

Operating systems and isolation

Containers and VMs use host-dependent runtimes such as gVisor, QEMU and Lume. macOS VMs require Apple silicon; Linux and Windows VM support depends on the host and image.

Cua runtimes and compute locations ↗

Warm pools and lifecycle

The local daemon can keep sandboxes ready, with minimum and maximum ready capacity and idle expiry. Suspend, resume and restart are local operations; cloud sandboxes have cleanup time limits.

Lifecycle and local warm pools ↗

Connecting and sharing

Connect directly on your network or through Cua's hosted relay. Sharing supports viewers and editors; Teams adds shared computers, roles and device approval.

How Cua Spaces works ↗

Resource limits

CPU, memory, disk and capacity depend on your machines, cloud provider and runtime. There is no single Cua-hosted sandbox size or hourly compute rate to compare here.

Licensing

Spaces is source-available under FSL-1.1-MIT, with each release converting to MIT after two years. Cua Driver and Lume use MIT licenses.
