SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @vercel/sandbox, and includes scripts (resource) components.

What problem does it solve?

This Skill addresses the need for a secure, isolated environment for running code and experimenting with different configurations without affecting the host system.

Core Features & Use Cases

  • Isolated Execution: Run untrusted code in a microVM to prevent potential system vulnerabilities.
  • Ephemeral Environments: Easily create temporary environments that can be destroyed upon completion to maintain a clean, secure workspace.
  • Dev Servers: Start development servers with ease for testing in isolation, reducing risks to the main system.
  • Use Case: For developers who need to test new code or run experiments without the risk of affecting their main development environment.

Quick Start

Use the sandbox skill to create a new microVM with Node.js 24 runtime and expose port 3000, then connect to the development server.

FAQPage Schema
How do I create an isolated Linux MicroVM for running untrusted code?

You can create an isolated Linux MicroVM by using the provided SDK and CLI to run untrusted code safely. This prevents potential system vulnerabilities and stops code execution from interfering with your host system.

What is the best way to test development servers without affecting my main environment?

The best way to test development servers safely is by using ephemeral MicroVM environments. You can start isolated dev servers for testing and easily destroy the temporary environment upon completion to maintain a clean workspace.

Can I expose a specific port like 3000 when running code in a sandbox?

Yes, you can expose specific ports like 3000 when running code in a sandbox. The quick start demonstrates creating a MicroVM with a Node.js 24 runtime, exposing port 3000, and connecting to the development server.

Does the sandbox skill provide an SDK and CLI for scripting and managing environments?

Yes, the sandbox skill provides both an SDK and a CLI for scripting and managing isolated Linux MicroVMs. This allows you to automate the creation, management, and execution of these ephemeral environments.

When should I use a MicroVM instead of running code directly on my host system?

You should use a MicroVM when you need to experiment with different configurations or run untrusted code. It provides a secure, isolated execution environment that prevents interference with your host system or other projects.
