Introduction

What is ComputeSDK?

ComputeSDK is an open-source toolkit for running other people’s code in your applications. Think of it as the “AI SDK for compute” - providing a consistent TypeScript interface whether you’re using Railway, E2B, Vercel, Daytona, Modal, and more.

How It Works

ComputeSDK operates on three core concepts:

Sandboxes - Isolated compute environments where code executes safely
Providers - Cloud platforms hosting the sandboxes (E2B, Modal, Railway, etc.)
Gateway - ComputeSDK’s orchestration layer that unifies provider APIs

When you call compute.sandbox.create(), ComputeSDK:

1. Detects your configured provider from environment variables
2. Provisions a new sandbox on that provider
3. Returns a unified interface regardless of underlying provider
4. Handles provider-specific authentication, API quirks, and errors

This means you write code once and can switch providers by changing environment variables - no code changes required.

Why ComputeSDK?

🔄 Provider-agnostic - Switch between Railway, E2B, Vercel, Daytona, Modal and more without code changes
🛡️ Security-first - Isolated sandboxes protect your infrastructure
⚡ Developer experience - Simple, TypeScript-native API
🌍 Production-ready - Used by teams building the next generation of developer tools

Perfect for building:

• Code execution platforms - Run user-submitted code safely
• Educational tools - Interactive coding environments
• Data analysis applications - Process code with filesystem access
• AI-powered development tools - Let AI agents write and execute code
• Testing & CI/CD systems - Isolated test environments

Features

🚀 Multi-provider support - Railway, E2B, Vercel, Daytona, Modal and more
📁 Filesystem operations - Read, write, create directories
⚡ Command execution - Run shell commands directly
🛡️ Type-safe - Full TypeScript support with comprehensive error handling
📦 Simplicity - Auto detection of providers and simple setup

Quick Example

npm install computesdk

export COMPUTESDK_API_KEY=your_computesdk_api_key

export PROVIDER_API_KEY=your_provider_api_key

import { compute } from 'computesdk';

// computeSDK will auto detect the provider

// Create a sandbox
const sandbox = await compute.sandbox.create();

// Execute code
const result = await sandbox.runCode('print("Hello World!")');
console.log(result.output); // "Hello World!"

// Clean up
await compute.sandbox.destroy(sandbox.sandboxId);
