E2B

What is E2B?

E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.

Run your first Sandbox

1. Install SDK

JavaScript / TypeScript

npm i e2b

Python

pip install e2b

2. Get your E2B API key

1. Sign up to E2B here.
2. Get your API key here.
3. Set environment variable with your API key

E2B_API_KEY=e2b_***

3. Start a sandbox and run commands

JavaScript / TypeScript

import Sandbox from 'e2b'

const sandbox = await Sandbox.create()
const result = await sandbox.commands.run('echo "Hello from E2B!"')
console.log(result.stdout) // Hello from E2B!

Python

from e2b import Sandbox

with Sandbox.create() as sandbox:
    result = sandbox.commands.run('echo "Hello from E2B!"')
    print(result.stdout)  # Hello from E2B!

4. Code execution with Code Interpreter

If you need to execute code with runCode()/run_code(), install the Code Interpreter SDK (JavaScript / Python):

npm i @e2b/code-interpreter  # JavaScript/TypeScript
pip install e2b-code-interpreter  # Python

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

const sandbox = await Sandbox.create()
const execution = await sandbox.runCode('x = 1; x += 1; x')
console.log(execution.text)  // outputs 2

5. Computer use with Desktop

For mouse, keyboard, screenshot, application, and desktop streaming APIs, install the Desktop SDK (JavaScript / Python):

npm i @e2b/desktop  # JavaScript/TypeScript
pip install e2b-desktop  # Python

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()
await desktop.launch('google-chrome')
const screenshot = await desktop.screenshot()

7. E2B cookbook

Visit our Cookbook to get inspired by examples with different LLMs and AI frameworks.

Self-hosting

Read the embed deployment guide to learn how to set up the E2B runtime on your own. The infrastructure is deployed using Terraform.

Supported cloud providers:

• 🟢 AWS
• 🟢 Google Cloud (GCP)
• 🟢 Azure
