E2B

Minor Changes

• 48e9249: Bump @npmcli/package-json from ^5.2.1 to ^7.0.5, clearing the last npm warn deprecated glob@10.5.0 warning printed on every @e2b/cli install (@npmcli/package-json@5 pinned glob@10; 7.0.4 moved to glob@13). Together with the e2b glob bump, a fresh npm install @e2b/cli is now warning-free and drops from 183 to 145 packages.

@npmcli/package-json@7 requires Node ^20.17.0 || >=22.9.0, so the CLI's Node 22 floor moves from >=22 to >=22.9.0. Node 20 support is unchanged (>=20.18.1 <21). Only the PackageJson.load/create/update/save API used by e2b template init is touched, and it is unchanged across the bump.

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:

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. Check docs

Visit E2B documentation.

6. E2B cookbook

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

Self-hosting

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