E2B

Overview

E2B solves a critical problem: how do you let an AI agent run code without risking your system? E2B provides isolated cloud sandboxes that spin up in ~150ms, execute any code, and destroy instantly.

How It Works

1. Create sandbox — Spins up in ~150ms
2. Execute code — Python, JavaScript, Bash, or any language
3. Get results — stdout, stderr, files, artifacts
4. Destroy — Clean up automatically

Use Cases

• Code generation — Let agents write and test code safely
• Data analysis — Run pandas, matplotlib in isolation
• Research — Execute computational experiments
• Education — Safe code execution for AI tutoring

Getting Started

from e2b_code_interpreter import Sandbox

sandbox = Sandbox()
result = sandbox.run_code("print('Hello from sandbox!')")
print(result.text)
sandbox.kill()

Example

sandbox = Sandbox()
code = """
import pandas as pd
data = pd.DataFrame({'x': range(10), 'y': [i**2 for i in range(10)]})
print(data.describe())
"""
result = sandbox.run_code(code)

Alternatives

• CUA — Desktop sandboxes for computer-use agents
• Docker — Self-managed containers
• Modal — Serverless compute platform
