SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @vercel/sandbox, ms.

What problem does it solve?

This Skill solves the security and environment-consistency risks associated with running untrusted code or complex build processes on your local machine or production servers.

Core Features & Use Cases

Isolated Execution: Run untrusted code, scripts, or binaries in ephemeral, sandboxed Linux environments.
DevOps & Testing: Spin up temporary development servers, run integration tests, or perform build tasks in a clean, reproducible environment.
Use Case: When you need to test a potentially risky script or build a project with specific system dependencies without polluting your host OS, this Skill provisions a dedicated MicroVM to handle the task safely.

Quick Start

Use the sandbox skill to create a new node24 environment and execute the npm install command inside it.

FAQPage Schema

How do I run untrusted code in an isolated Linux environment?▼

To run untrusted code in an isolated Linux environment, this Skill provisions ephemeral, sandboxed Linux MicroVMs using the Vercel Sandbox SDK, ensuring secure execution without polluting your host OS.

Can I spin up temporary development servers for integration testing?▼

Yes, you can spin up temporary development servers for integration testing. This Skill creates ephemeral dev servers within isolated MicroVMs to run build tasks and tests in clean, reproducible environments.

Does Vercel Sandbox support network-restricted execution environments?▼

Vercel Sandbox supports network-restricted execution environments. It provisions isolated Linux MicroVMs designed to satisfy constraints for resource-constrained, network-restricted, and persistent execution.

What is the best way to execute build pipelines without risking local machine security?▼

The best way to execute build pipelines without risking local machine security is using isolated Linux MicroVMs. This Skill handles complex build processes and untrusted scripts safely away from your production servers.

How do I create a node24 environment to execute npm install commands?▼

You can create a node24 environment and execute npm install commands by using the sandbox Skill to provision a dedicated MicroVM, facilitating secure, isolated system-level task execution.

Why use microvm isolation for executing untrusted scripts?▼

MicroVM isolation is used for executing untrusted scripts because it provides a secure, ephemeral Linux environment that prevents environment-consistency risks and protects your host OS from potentially risky operations.
