CapabilitiesStorage
Separate volumes
Storage that lives on after the machine is deleted and can be attached to a new one.
Short answer: 8 of 16 providers offer it fully: Blaxel, Daytona, Lizard, Modal, Runtime, Tensorlake, Vercel Sandbox and boxd. With a catch: Cloudflare Sandbox, E2B and Morph. Checked 29 October 2026.
Who offers it
Part of Storage: disk, volumes and what persists, which explains why it matters.
Fully: Blaxel, boxd, Daytona, Lizard, Modal, Runtime, Tensorlake and Vercel Sandbox. With a catch: Cloudflare Sandbox, E2B and Morph. Not at all: Agent 37, Boat, InstaBox, Sandboxer and Sprites.
- BlaxelYes
Note: Only one volume attaches to a sandbox, and it attaches to one sandbox at a time.
docs-confirmed “Blaxel Volumes provide persistent storage that survives sandbox destruction and recreation.” Source
- boxdYes
Note: A disk attaches to one machine at a time and lives on one host.
docs-confirmed “A disk is standalone storage that outlives the machine it is attached to.” Source
- DaytonaYes
Note: Volumes are network filesystems, not block disks, so a database table store is a poor fit.
docs-confirmed “Volumes are FUSE-based mounts that provide shared file access across Daytona sandboxes.” Source
Note: A volume attaches to one sandbox at a time and lives on one node.
docs-confirmed “Persistent Volumes keep data after a sandbox stops.” Source
Volumes survive the sandbox and are not included in snapshots.
docs-confirmed “Volumes are backed by multiple underlying cloud providers to guarantee high availability.” Source
Each volume attaches at a path, read-write or as a read-only snapshot.
docs-confirmed “A create attaches up to four volumes, each at a path such as `/data`, in one of two modes” Source
- TensorlakeYes
A Cloud Volume can be mounted on one or more sandboxes, read-only if you choose.
docs-confirmed “Mount durable, shareable Tensorlake filesystems into sandboxes at boot, on warm-pool claims, or on a running sandbox” Source
A drive outlives the sandbox and can be attached to another.
docs-confirmed “A drive defaults to 1 TiB when you do not set a size (1 GiB for Hobby).” Source
The catch: There is no separate disk that outlives the machine; a bucket can be mounted, and a snapshot lasts 30 days.
docs-confirmed “Mounted buckets outlive every instance” Source
- E2BWith a catch
The catch: Volumes exist but are in private beta and need access from support.
docs-confirmed “Volumes are currently in private beta.” Source
- MorphWith a catch
The catch: The volume is object storage reached over S3, not a disk attached to the machine.
docs-confirmed “Morph Volumes are persistent S3-compatible storage for build caches, release artifacts, checkpoints, and shared datasets.” Source
- Agent 37No
No separate volume product; the instance disk is the only storage.
inferred “The whole disk persists, like a VM.” Source
- BoatNo
No separate volume product.
inferred “A saved snapshot is a copy of a sandbox disk that you save under a name.” Source
- InstaBoxNo
One disk per machine; no separate volume.
docs-confirmed “A machine has one disk, `/data` (home is `/data/home`), 20 GiB by default.” Source
No separate volume product; the machine's own disk is the only storage.
inferred “"Disk" is space for your files, added on top of the OS image” Source
- SpritesNo
No attachable or shared volume; storage belongs to the Sprite.
inferred “The split is simple: disk persists, memory does not.” Source
