E2B Documentation

What is E2B?

E2B provides isolated sandboxes that let agents safely execute code, process data, and run tools. Our SDKs make it easy to start and manage these environments. Start a sandbox and run code in a few lines:

npm i e2b

pip install e2b

import { Sandbox } from 'e2b'

const sandbox = await Sandbox.create() // Needs E2B_API_KEY environment variable
const result = await sandbox.commands.run('echo "Hello from E2B Sandbox!"')
console.log(result.stdout)

from e2b import Sandbox

sandbox = Sandbox.create()  # Needs E2B_API_KEY environment variable
result = sandbox.commands.run('echo "Hello from E2B Sandbox!"')
print(result.stdout)

E2B building blocks

A quick overview of the core building blocks you’ll interact with when using E2B.

Sandbox — A fast, secure Linux VM created on demand for your agent, which you can pause and resume as needed
Template — Defines what environment a sandbox starts with
Persistence — Pausing a sandbox saves both its filesystem and its memory, and paused sandboxes are kept indefinitely until you kill them

How to use the docs

The documentation is split into three main sections:

Quickstart — Step-by-step tutorials that walk you through creating your first E2B sandboxes.
Examples — In-depth tutorials focused on specific use cases. Pick the topics that match what you’re building.
SDK Reference — A complete technical reference for every SDK method, parameter, and configuration option.

Working with an AI coding agent? These docs are served for machines too. Point your agent at the docs MCP server at https://docs.e2b.dev/mcp (public, no authentication needed), or give it https://docs.e2b.dev/llms.txt for the full page index. Every page also serves its Markdown source at the same URL with .md appended.
