A Sandbox Template names where an agent’s commands run: the Bashkit Virtual Workspace or a managed provider such as Daytona or E2B, with its credential source, durability and lifecycle. Editing a template creates a new immutable revision, and existing sessions keep the revision they started with. An agent’s sandbox policy decides whether a session can pick or override the template.

**In the UI:** open **Sandbox Templates** and select **New Sandbox Template**. The **Sandboxes** page lists every sandbox across providers and states, with a lifecycle timeline, a **Needs attention** filter and pause, resume and delete in the detail drawer. Both sit in the collapsible **Sandboxes** sidebar group.

**In code:** `GET /v1/sandboxes` lists the fleet; `/stats` and `/timeline` back the page.
