Snapshots

Create, list, and delete snapshots — the frozen disk images sandboxes boot from.

A snapshot is a frozen disk image built from a base OCI image plus your setup steps. Once built, it’s reusable forever — every sandbox you launch from it boots in under 100 ms because the upper layer is pre-populated.

If you’re coming from Docker: a snapshot is the equivalent of an image. See Concepts for the full mapping.
