What is E2B?

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

Note

This repository contains the core E2B SDK that's used in our main E2B Code Interpreter SDK.

Run your first Sandbox

1. Install SDK

JavaScript / TypeScript

npm i @e2b/code-interpreter

Python

pip install e2b-code-interpreter

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. Execute code with code interpreter inside Sandbox

JavaScript / TypeScript

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

const sandbox = await Sandbox.create()
await sbx.runCode('x = 1')

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

Python

from e2b_code_interpreter import Sandbox

with Sandbox() as sandbox:
    sandbox.run_code("x = 1")
    execution = sandbox.run_code("x+=1; x")
    print(execution.text)  # outputs 2
