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.

JavaScript / TypeScript

npm i e2b

Python

pip install e2b

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

E2B_API_KEY=e2b_***

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!

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

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

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

Read the self-hosting guide to learn how to set up the E2B infrastructure on your own. The infrastructure is deployed using Terraform.
