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
bash
npm install computesdk
bash
# .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
typescript
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:
typescript
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
typescript
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.
