SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @vercel/sandbox.

What problem does it solve?

Vercel Sandbox guidance helps you execute untrusted or AI-generated code in isolation so your app and infrastructure stay protected from unsafe behavior.

Core Features & Use Cases

  • Ephemeral Firecracker microVM execution: Run code in a short-lived VM with a tight isolation boundary.
  • Browser automation in isolation: Execute agent-browser + headless Chromium workflows for tasks like screenshotting and accessibility/snapshot capture.
  • Fast startup via sandbox snapshots: Preinstall system dependencies and tools so sandbox runs start in sub-second time.
  • Secure execution configuration: Use Vercel OIDC credentials on Vercel or explicit Vercel tokens for local control.

Quick Start

Create a Vercel Sandbox execution helper for your project, then run your untrusted code or agent-browser commands inside the sandbox with an optional snapshot for faster boot.

Frequently Asked Questions about vercel-sandbox

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

FAQPage Schema
How do I safely execute untrusted or AI-generated code in isolation?▼

Safely executing untrusted code requires ephemeral Firecracker microVMs that provide a tight isolation boundary, which you can create using the Vercel Sandbox package's Sandbox.create() method.

Can I run headless Chromium and browser automation tasks inside a secure sandbox?▼

Yes, headless Chromium browser automation can run inside the Vercel Sandbox using agent-browser workflows, allowing isolated execution for tasks like screenshotting and accessibility snapshot capture.

How do I speed up microVM startup time for frequent code execution?▼

MicroVM startup time can be reduced to sub-second speeds by using sandbox snapshots, which preinstall system dependencies and tools so execution environments boot instantly.

What authentication is required to run Vercel Sandbox locally?▼

Running Vercel Sandbox locally requires explicit Vercel tokens for authentication and environment control, whereas deployments on Vercel can automatically use Vercel OIDC credentials.

Does Vercel Sandbox work for server-side tool execution in agent workflows?▼

Yes, Vercel Sandbox is designed for server-side tool execution and scheduled agent workflows, providing strict run boundaries and secure isolation for dynamic command execution.
