Wakes on a socket

Any TCP connection. No SDK, no client library, no wrapper.

Sleeps to 0 B

Idle sandboxes cost no memory. Volume intact, back in a second.

One committed file

sandbox.json, or a built-in template with nothing on disk.

Snapshot & fork

Seed once, fork many. The migration runs a single time.

Docker or Kubernetes

The same spec local or in a cluster. sbx doctor tells you.

Live dashboard

sbx ui — cpu, memory and a trace, per sandbox.
