Docker Cloud Sandboxes Docker Cloud Sandboxes extend microVM-based isolation for AI coding agents from local laptops to Docker-managed cloud compute. Developers can start agents locally, move them to the cloud with one command, run unattended for hours or overnight, and scale many parallel sandboxes without provisioning infrastructure. The product includes pre-built kits for agents such as Claude Code and Codex, MCP gateway, secret injection, and network policies, with pay-as-you-go compute billed by the second.
