# E2B Documentation (/docs)

<!-- agent-signals: reading_time_min: 1 · est_tokens: 518 · updated: 2026-07-30 -->

## 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:

<CodeGroup>
```bash title="JavaScript & TypeScript"
npm i e2b
```

```bash title="Python"
pip install e2b
```
</CodeGroup>

<CodeGroup>
```javascript title="JavaScript & TypeScript"
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)
```

```python title="Python"
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)
```
</CodeGroup>

## E2B building blocks

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

* [**Sandbox**](/docs/sandbox) — A fast, secure Linux VM created on demand for your agent

* [**Template**](/docs/template/quickstart) — Defines what environment a sandbox starts with

## How to use the docs

The documentation is split into three main sections:

* [**Quickstart**](#quickstart) — Step-by-step tutorials that walk you through creating your first E2B sandboxes.

* [**Examples**](#examples) — In-depth tutorials focused on specific use cases. Pick the topics that match what you're building.

* [**SDK Reference**](https://e2b.dev/docs/sdk-reference) — A complete technical reference for every SDK method, parameter, and configuration option.
