Drives for Vercel Sandbox are now in public beta

Drives for Vercel Sandbox are now available in public beta on Hobby, Pro, and Enterprise.

A Drive is persistent storage that you mount as a directory in a Vercel Sandbox. It isn’t tied to a single sandbox, so you can reuse the same Drive across runs and different sandbox instances.

Use Drives to preserve an agent's workspace or on-disk memory, or to reuse datasets, models, and dependency trees.

Copy link to headingCreate and mount a Drive

Create or retrieve a Drive and mount it at a path when starting a sandbox. Read and write files through the sandbox filesystem at that path.

1
import { Sandbox, Drive } from '@vercel/sandbox';
2

3
const workspace = await Drive.getOrCreate({ 
4
  name: 'agent-workspace', 
5
});
6

7
const sandbox = await Sandbox.create({
8
  mounts: { '/data': workspace },
9
});

Anything stored under /data remains on the Drive after the sandbox stops.

Copy link to headingShare Drive data across sandboxes

A Drive supports one read-write mount at a time. After the Drive has been written to, multiple sandboxes can read from it concurrently by mounting point-in-time, read-only snapshots.

1
import { Sandbox, Drive } from '@vercel/sandbox';
2

3
const workspace = await Drive.getOrCreate({
4
  name: 'agent-workspace',
5
});
6

7
// The Drive must have been written to at least once.
8
const [reviewSandbox, testSandbox] = await Promise.all([
9
  Sandbox.create({
10
    mounts: { '/data': workspace.snapshot() },
11
  }),
12
  Sandbox.create({
13
    mounts: { '/data': workspace.snapshot() },
14
  }),
15
]);

Each snapshot reflects the Drive at the moment it's mounted. Later writes aren’t included; mount a new snapshot to access them.

Copy link to headingLimits and pricing

Each sandbox can mount up to four Drives at separate paths. Drives default to a maximum size of 1 TiB (1 GiB on Hobby) and can be configured up to 16 TiB, with higher limits available by request.

Drives are available in every Sandbox region. Each Drive stays in the region where it was created. Sandboxes that mount it must run in that region and can’t use failover regions.

Drive pricing is based on storage, reads, and writes, with rates varying by region. In iad1, storage costs $0.05 per GB-month, reads $0.0015 per GB, and writes $0.004 per GB. Hobby includes 15 GB of Drive storage and 30 GB each of reads and writes per month. See Sandbox pricing for regional rates and plan details.
