# E2B

> Open-source, secure environment for running AI-generated code in isolated sandboxes.

E2B provides a platform to run AI-generated code securely within isolated environments. It offers SDKs for both Python and JavaScript/TypeScript allowing the creation of sandboxes where code can be executed safely.

## What is E2B?
[E2B](https://www.e2b.dev/) 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](https://www.npmjs.com/package/e2b) or [Python SDK](https://pypi.org/project/e2b).

## 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](https://e2b.dev).
2. Get your API key [here](https://e2b.dev/dashboard?tab=keys).
3. Set environment variable with your API key
```
E2B_API_KEY=e2b_***
```

### 3. Start a sandbox and run commands

JavaScript / TypeScript
```ts
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
```py
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()`](https://e2b.dev/docs/code-interpreting)/[`run_code()`](https://e2b.dev/docs/code-interpreting), install the [Code Interpreter SDK](https://github.com/e2b-dev/code-interpreter):

```
npm i @e2b/code-interpreter  # JavaScript/TypeScript
pip install e2b-code-interpreter  # Python
```

```ts
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](https://e2b.dev/docs).

### 6. E2B cookbook
Visit our [Cookbook](https://github.com/e2b-dev/e2b-cookbook/tree/main) to get inspired by examples with different LLMs and AI frameworks.

## Self-hosting

Read the [self-hosting guide](https://github.com/e2b-dev/infra/blob/main/self-host.md) to learn how to set up the [E2B infrastructure](https://github.com/e2b-dev/infra) on your own. The infrastructure is deployed using Terraform. 

Supported cloud providers:
- 🟢 AWS
- 🟢 Google Cloud (GCP)
- [ ] Azure
- [ ] General Linux machine
```
