Nido — Fast, Simple VM Sandboxes for AI Agents (Temporary & Persistent)

Spin up QEMU/KVM virtual machines directly from Claude for testing, sandboxing, or running isolated workloads. Built specifically for AI agents to programmatically manage VMs without manual intervention. You can create throwaway Linux instances for one-off tasks or maintain persistent environments that survive between sessions. Useful when you need actual compute isolation beyond containers, want to test across different distros, or need to run something in a clean environment that you can snapshot and discard. The automation-first design means operations are exposed as tool calls rather than interactive commands.
