SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a secure, isolated environment to execute untrusted or AI-generated code, preventing potential harm to your system.

Core Features & Use Cases

  • Isolated Execution: Runs code within ephemeral Firecracker microVMs, ensuring complete isolation.
  • Runtime Support: Supports Node.js and Python runtimes.
  • Use Case: An AI agent generates a script to test a new feature. Use Vercel Sandbox to run this script without risking your local development environment.

Quick Start

Use the vercel-sandbox skill to run the provided nodejs code safely.

Frequently Asked Questions about vercel-sandbox

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run untrusted code safely in an isolated environment?▼

Isolated code execution works by running untrusted scripts inside ephemeral Firecracker microVMs. This mechanism ensures complete system isolation, preventing AI-generated or user-generated code from causing harm to your local development environment.

Can I execute Python and Node.js scripts generated by AI agents securely?▼

Yes, you can execute AI-generated Python and Node.js scripts securely. The sandbox environment supports both runtimes, allowing AI agents to generate and test feature scripts without risking your local development environment.

What is the best way to test AI-generated code without risking my local setup?▼

The best way to test AI-generated code safely is using a sandbox with Firecracker microVMs. This creates an isolated execution environment, ensuring untrusted scripts run ephemerally without risking your local development setup.

Does code execution in a sandbox support runtimes other than Node.js and Python?▼

Currently, the sandbox environment explicitly supports Node.js and Python runtimes for isolated code execution. While designed for experimentation, the metadata mentions no support for additional runtimes.

Why do I need a microVM to isolate untrusted code execution?▼

You need a microVM to isolate untrusted code execution because it provides a secure, ephemeral environment. This ensures that even if the code behaves maliciously, it remains completely contained within the Firecracker microVM.
