Volumes are persistent, team scoped filesystems that you can attach to a sandbox at launch. You can attach a volume to multiple sandboxes, and a volume is synced across writes. A volume persists even after all sandboxes are stopped, so you can completely isolate your data needs from your sandbox compute.

Quick Start

  1. Create a volume.
  2. Mount it when creating a sandbox.
  3. Read and write files at the mount path.

Why Volumes

Use volumes when you need data to outlive a sandbox and be reused later:
  • Persistent workspaces for agents.
  • Reusable caches across runs.
  • Shared read only data mounted into multiple sandboxes over time.

Volume Lifecycle

  • Create volumes via SDKs, volume endpoints, or hx volume.
  • Mount volumes during sandbox creation
  • Access files through the mounted path with normal sandbox filesystem operations.
