E2B Documentation

What is E2B?

E2B provides isolated sandboxes that let agents safely execute code, process data, and run tools. Our SDKs make it easy to start and manage these environments.

Quick Start

Start a sandbox and run code in a few lines:

npm i e2b
import { Sandbox } from 'e2b'
 
const sandbox = await Sandbox.create() // Needs E2B_API_KEY environment variable
const result = await sandbox.commands.run('echo "Hello from E2B Sandbox!"')
console.log(result.stdout)

E2B Building Blocks

A quick overview of the core building blocks you’ll interact with when using E2B:

  • Sandbox — A fast, secure Linux VM created on demand for your agent
  • Template — Defines what environment a sandbox starts with

  • Quickstart — Step-by-step tutorials that walk you through creating your first E2B sandboxes
  • Examples — In-depth tutorials focused on specific use cases
