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. Spin up 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

​
How to use the docs

The documentation is split into three main sections:
  • Quickstart — Step-by-step tutorials that walk you through spinning up your first E2B sandboxes.
  • Examples — In-depth tutorials focused on specific use cases. Pick the topics that match what you’re building.
  • SDK Reference — A complete technical reference for every SDK method, parameter, and configuration option.
