E2B — Ejecución de Código en Sandbox para IA

Eres un experto en E2B, la plataforma en la nube para ejecutar código generado por IA en sandboxes seguras. Ayudas a los desarrolladores a dotar a los agentes de IA de la capacidad de ejecutar código, instalar paquetes, leer/escribir archivos y ejecutar procesos largos en entornos aislados en la nube — cada sandbox es una VM ligera que arranca en ~150ms con Linux completo, sistema de archivos y red.

¿Qué es E2B — Ejecución de Código en Sandbox para IA?

E2B es una plataforma en la nube diseñada para ejecutar código generado por IA de forma segura dentro de sandboxes aisladas. Permite a los desarrolladores otorgar a sus agentes de IA la capacidad de ejecutar código Python o JavaScript, instalar paquetes mediante pip, realizar operaciones de archivos y ejecutar procesos prolongados en entornos ligeros tipo VM que arrancan en aproximadamente 150 milisegundos. Esta habilidad es especialmente útil para asistentes de codificación como Claude Code, Cursor o Codex, ya que les permite delegar la ejecución de código real a un entorno seguro y controlado. El flujo de trabajo típico implica la creación de una sandbox, la ejecución de código (con soporte para bibliotecas populares como NumPy, Pandas y Matplotlib), la manipulación de archivos (lectura/escritura) y la eventual destrucción del sandbox para garantizar la seguridad. E2B también ofrece características avanzadas como plantillas de sandbox personalizadas, tiempos de espera configurables y acceso a internet, lo que lo convierte en una herramienta ideal para integrar en marcos como LangChain, CrewAI o Mastra.

¿Qué hace E2B — Ejecución de Código en Sandbox para IA?

Eres un experto en E2B, la plataforma en la nube para ejecutar código generado por IA en sandboxes seguras. Ayudas a los desarrolladores a dotar a los agentes de IA de la capacidad de ejecutar código, instalar paquetes, leer/escribir archivos y ejecutar procesos largos en entornos aislados en la nube — cada sandbox es una VM ligera que arranca en ~150ms con Linux completo, sistema de archivos y red.

Capacidades Principales

import { Sandbox } from "@e2b/code-interpreter";

const sandbox = await Sandbox.create();

// Ejecutar Python
const result = await sandbox.runCode(`
import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame({"x": range(10), "y": [i**2 for i in range(10)]})
plt.figure(figsize=(8, 5))
plt.plot(df.x, df.y)
plt.title("Crecimiento Cuadrático")
plt.savefig("/tmp/chart.png")
print(f"Puntos de datos: {len(df)}")
`);
console.log(result.text);     // "Puntos de datos: 10"
console.log(result.results);  // [{ type: "png", data: "base64..." }]

// Instalar paquetes sobre la marcha
await sandbox.runCode("!pip install scikit-learn");
await sandbox.runCode(`
from sklearn.linear_model import LinearRegression
model = LinearRegression().fit([[1],[2],[3]], [1,2,3])
print(model.predict([[4]]))
`);

// Operaciones con archivos
await sandbox.files.write("/home/user/data.csv", csvContent);
const output = await sandbox.runCode("import pandas as pd; print(pd.read_csv('/home/user/data.csv').head())");
const fileBytes = await sandbox.files.read("/tmp/chart.png");

// Ejecución de JavaScript/TypeScript
const jsResult = await sandbox.runCode(`
const response = await fetch('https://api.github.com/repos/e2b-dev/e2b');
const data = await response.json();
console.log(data.stargazers_count);
`, { language: "javascript" });

await sandbox.kill();

Instalación

npm install @e2b/code-interpreter

Mejores Prácticas

  1. Arranque en 150ms — Las sandboxes se inician casi instantáneamente; créalas por solicitud para aislamiento
  2. Paquetes preinstalados — NumPy, Pandas, Matplotlib disponibles por defecto; instala más con pip
  3. Entrada/Salida de archivos — Sube datos, descarga resultados; las sandboxes tienen acceso completo al sistema de archivos
  4. Gráficos como base64 — Los gráficos de Matplotlib/Plotly se devuelven como imágenes base64; renderízalas en tu interfaz de usuario
  5. Plantillas personalizadas — Crea plantillas de sandbox con paquetes preinstalados para un inicio más rápido
  6. Tiempo de espera — Establece un tiempo de espera en la sandbox; se elimina automáticamente después de la duración; previene procesos descontrolados
  7. Red — Las sandboxes tienen acceso a internet; obtén datos de APIs, descarga datos, instala desde PyPI
  8. Integración con agentes — Úsalo como herramienta en agentes de LangChain/CrewAI/Mastra; la IA escribe código, E2B lo ejecuta
