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.

[!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
