Volumes
Volumes are in private beta — ask at support@e2b.dev. Known limits today: file locking, performance with many small files, and file ownership.
Three ways to use one#
Shared — One volume mounted into many sandboxes: a dataset, a cache, a model.
Dedicated — One volume per sandbox, so a user's workspace survives across sessions.
Standalone — No sandbox at all: upload and download through the SDK.
Create and mount#
import { Volume, Sandbox } from 'e2b'
const volume = await Volume.create('my-volume')
const sandbox = await Sandbox.create({
volumeMounts: {
'/mnt/my-data': volume,
},
})from e2b import Volume, Sandbox
volume = Volume.create('my-volume')
sandbox = Sandbox.create(
volume_mounts={
'/mnt/my-data': volume,
},
)Inside the sandbox the files are plain files at /mnt/my-data. Outside it, the SDK manages, reads, writes, uploads and downloads — see E2B's volume guides.
