SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides structured guidance for using Vercel Sandbox to execute untrusted code safely within ephemeral Firecracker microVMs, enabling isolated experimentation, AI-agent workflows, and browser automation.

Core Features & Use Cases

  • Ephemeral microVMs for on-demand, isolated code execution.
  • Supports agent-browser workflows and browser automation in a secure sandbox.
  • Guidance for integrating with Next.js, SvelteKit, Nuxt, Remix, Astro, and other frameworks to run code safely.

Quick Start

Import the sandbox package, create a sandbox instance, run your code inside it, and stop the instance when complete.

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 securely in an isolated environment?▼

Vercel Sandbox executes untrusted code securely inside ephemeral Firecracker microVMs, providing complete isolation for on-demand experimentation and AI-agent workflows without risking your host environment.

Can I use Vercel Sandbox for browser automation with AI agents?▼

Yes, Vercel Sandbox supports agent-browser workflows and browser automation tasks within a secure, isolated microVM, enabling AI agents to operate safely without risking the host system.

Does Vercel Sandbox work with Next.js, SvelteKit, and Astro frameworks?▼

Yes, Vercel Sandbox integrates with Next.js, SvelteKit, Nuxt, Remix, and Astro frameworks, allowing you to execute code and run development workflows safely within isolated microVMs.

What's the best way to manage sandbox lifecycle and credentials?▼

Use node-based controls to create, run, and stop sandbox instances, handle environment credentials securely, and utilize optional sandbox snapshots to achieve faster startup times for subsequent executions.

How do Firecracker microVMs provide isolation for code execution?▼

Firecracker microVMs provide isolation by creating ephemeral, lightweight virtual machines that act as secure boundaries, ensuring untrusted code executes independently without affecting the underlying host system.

When should I use ephemeral microVMs for isolated experimentation?▼

Use ephemeral microVMs when running untrusted code, testing AI-agent workflows, or performing browser automation that requires strict security isolation and a clean, temporary execution environment.
