Deno Sandboxes

ID	deno
Category	Sandboxes
Features	None
Dependencies	session_storage

Run code in cloud-based Deno sandboxes. Create isolated Linux microVMs, execute commands, and manage files. Each sandbox is scoped to the session and supports configurable memory and network policies.

Experimental: This capability may change in future releases.

Notes

• Sandboxes are isolated Linux microVMs with network access (subject to allow_net)
• Sandboxes are automatically tracked for the session; use deno_manage_sandbox to delete when done
• File operations target the sandbox filesystem, not the session workspace
