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.
