Local Sandboxes

Create and use isolated computers on your own hardware.

The Cua Sandbox SDK represents one isolated computer. In the local path, a runtime on your own hardware creates and runs that computer; you do not need a hosted Fleet pool or claim.

Start with Create and manage a local Sandbox to choose a supported runtime, create a Sandbox, reconnect when needed, and clean it up. Check Sandbox runtime support before choosing an operating system or image kind.
