E2B Sandboxes with ComputeSDK

Run code in E2B's Firecracker microVMs through ComputeSDK's unified API. E2B provides sub-second cold starts and secure isolation — ideal for AI code execution, data science, and educational platforms.

Setup

npm install computesdk

# .env
COMPUTESDK_API_KEY=your_computesdk_api_key
E2B_API_KEY=your_e2b_api_key

Get your ComputeSDK key at https://console.computesdk.com/register

Quick Start

import { compute } from 'computesdk';
// Auto-detects E2B from environment variables

const sandbox = await compute.sandbox.create();

const result = await sandbox.runCode('print("Hello from E2B!")');
console.log(result.output);

await sandbox.destroy();

Explicit Configuration

For multi-provider setups or when you want to be explicit:

import { compute } from 'computesdk';

compute.setConfig({
  computesdkApiKey: process.env.COMPUTESDK_API_KEY,
  provider: 'e2b',
  e2b: {
    apiKey: process.env.E2B_API_KEY,
  }
});

const sandbox = await compute.sandbox.create();

E2B Configuration Options

interface E2BConfig {
  apiKey?: string;              // Uses E2B_API_KEY env var if not set
  runtime?: 'node' | 'python'; // Auto-detects from code patterns
  timeout?: number;             // Execution timeout in ms
}

Runtime Detection

E2B auto-detects Python from print statements, import, def, and Python-specific syntax like f"strings". All other code defaults to Node.js.

Full API

ComputeSDK provides the same API across all providers: filesystem operations, shell commands, managed servers, overlays, terminals, and client access.
