A real VM, not a container
Get root on a VM with its own kernel, so Docker, Kubernetes, and systemd just work.

Drive it with AI
Let Claude, Codex, or any MCP client start this playground and run commands in it.
Read the docs →
Expose HTTP(S) ports
Give any web app running inside the VM a public URL - for yourself or to share with others.

Private networking
VMs reach the internet via NAT with no public IP; several VMs share bridge networks.

Ephemeral or persistent
By default, VMs are destroyed when the session ends; enable persistence to keep the disks for next time.
