SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @vercel/sandbox, agent-browser.

What problem does it solve? Running headless Chrome from a Vercel-deployed app is blocked by serverless binary size limits and missing system libraries. This Skill spins up an ephemeral Vercel Sandbox microVM with Chromium and agent-browser pre-installed, so browser automation works from any Vercel framework without infrastructure changes. ## Core Features & Use Cases - Ephemeral Browser VMs: Create on-demand Linux microVMs that execute agent-browser commands (open, snapshot, fill, click, screenshot) and shut down automatically. - Sandbox Snapshots: Pre-build a VM image with Chromium system dependencies and agent-browser for sub-second startup instead of ~30s installs. - Multi-Step Automation: Persist browser sessions across commands to fill forms, click elements, wait for network idle, and capture screenshots as base64. - Use Case: Add a scheduled Vercel Cron route that opens a competitor's pricing page daily, captures an accessibility snapshot, and stores the results for change monitoring. ## Quick Start Use the vercel-sandbox skill to open a URL in headless Chrome inside a Vercel Sandbox and return a screenshot of the page.

Frequently Asked Questions about vercel-sandbox

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

FAQPage Schema
How do I run headless Chrome in a Vercel serverless app?▼

Use the @vercel/sandbox SDK to create an ephemeral microVM, install Chromium system dependencies via dnf, then run agent-browser commands inside it. This bypasses serverless binary size limits that prevent bundling Chrome directly.

What is a Vercel Sandbox snapshot and why use one?▼

A sandbox snapshot is a saved VM image with system dependencies, agent-browser, and Chromium pre-installed. Booting from a snapshot reduces startup from roughly 30 seconds of installs to sub-second, making it recommended for production deployments.

Does Vercel Sandbox browser automation work with Next.js, SvelteKit, and Nuxt?▼

Yes, the pattern works identically across frameworks including Next.js, SvelteKit, Nuxt, Remix, and Astro. Only the server-side code location differs, such as route handlers in Next.js or server routes in Nuxt.

How do I authenticate the Vercel Sandbox SDK locally?▼

Set VERCEL_TOKEN, VERCEL_TEAM_ID, and VERCEL_PROJECT_ID environment variables for local development. On Vercel deployments, authentication happens automatically via OIDC with no configuration needed.

Can I schedule recurring browser tasks with Vercel Sandbox?▼

Yes, combine the sandbox pattern with Vercel Cron Jobs by defining a cron route that creates a sandbox, runs agent-browser commands, and processes results. Configure the schedule in vercel.json.
