SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the complexity of running browser automation in production by giving you a safe, isolated Vercel Sandbox environment for headless Chrome and agent-driven workflows.

Core Features & Use Cases

  • Isolated browser execution: Launch Chrome inside ephemeral microVMs without local binary limits or shared host risk.
  • Persistent multi-step sessions: Keep browser state across commands for form filling, navigation, screenshots, and accessibility snapshots.
  • Production automation patterns: Use it for scheduled checks, scraping, UI validation, and other browser tasks in frameworks like Next.js, SvelteKit, Nuxt, Remix, and Astro.
  • Fast startup with snapshots: Prebuild sandbox images so browser sessions start quickly with Chromium and agent-browser already installed.

Quick Start

Ask the assistant to run your target website inside a Vercel Sandbox, perform the browser steps you need, and return the resulting screenshot, snapshot, or extracted data.

FAQPage Schema
How do I run headless Chrome in production without installing the browser locally?▼

Headless Chrome runs inside isolated Vercel Sandbox microVMs, eliminating local browser installations. This approach safely executes browser automation tasks in production environments by using ephemeral instances.

Can I keep browser state across multiple automation steps in Next.js or SvelteKit?▼

Yes, Vercel Sandbox supports persistent multi-step sessions for Next.js, SvelteKit, Nuxt, Remix, and Astro. Browser state is preserved across commands for form filling, navigation, screenshots, and accessibility snapshots.

Do I need Vercel authentication to run agent-browser commands in a sandbox?▼

Yes, Vercel authentication is required to create isolated Chrome sessions and execute multi-step agent-browser commands safely. You also need the @vercel/sandbox package to manage the microVM environment.

How do I speed up browser session startup for scheduled checks and scraping?▼

You can prebuild sandbox snapshots with Chromium and agent-browser already installed. This allows fast startup for scheduled checks, scraping, and UI validation by bypassing runtime environment configuration.

What are the limitations of running browser automation in Vercel Sandboxes?▼

Browser automation in Vercel Sandboxes runs within ephemeral microVMs, meaning sessions are isolated and eventually discarded. Complex workflows require prebuilt snapshots and proper Vercel authentication to function reliably.
