E2B cloud sandbox is a secure and isolated cloud environment.

The sandbox allows you to:

• Access Linux OS
• Create, list, and delete files and directories
• Run commands
• Run isolated code
• Access the internet

Check docs here.

Use Sandbox.create to create a new sandbox.

Example

import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()
