SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve? Running headless Chrome inside Vercel-deployed apps is blocked by serverless binary size limits and missing system libraries. This Skill provides a pattern for spinning up ephemeral Vercel Sandbox microVMs with agent-browser and Chromium pre-installed, so any Vercel app can perform browser automation without infrastructure changes. ## Core Features & Use Cases - Ephemeral Browser VMs: Create on-demand Linux microVMs via the @vercel/sandbox SDK that run agent-browser commands and shut down automatically. - Sandbox Snapshots: Pre-build VM images with Chromium system dependencies for sub-second startup instead of ~30s installs. - Full Automation Workflows: Capture screenshots, extract accessibility snapshots, fill forms, and run multi-step interactions, with support for Vercel Cron for scheduled tasks. - Use Case: A Next.js app needs to screenshot competitor pricing pages daily. Use this Skill to create a sandbox, run agent-browser commands, return the screenshot as base64, and schedule it with a Vercel Cron job. ## 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 and agent-browser, then run browser commands via sandbox.runCommand. This avoids serverless binary size limits since Chrome runs inside the sandbox VM, not your function.

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, similar to a Docker image. Booting from a snapshot reduces startup from about 30 seconds to sub-second, which is 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. The only difference is where the server-side code lives, such as route handlers, server actions, or server API routes.

How do I authenticate the Vercel Sandbox SDK locally?▼

On Vercel deployments, the SDK authenticates automatically via OIDC. For local development, set the VERCEL_TOKEN, VERCEL_TEAM_ID, and VERCEL_PROJECT_ID environment variables, which are passed into Sandbox.create calls.

Can I schedule recurring browser automation tasks on Vercel?▼

Yes, combine the sandbox browser 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 with a crons entry.
