## 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.
