SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of running browser automation (headless Chrome + agent-browser) inside a Vercel app without hitting local binary size limits or risking polluting the main server environment.

Core Features & Use Cases

  • Ephemeral microVM browser automation: Executes agent-browser commands inside Vercel Sandbox microVMs that spin up on demand and shut down after use.
  • Headless Chrome without heavy deployment coupling: Lets you perform tasks like scraping, page interaction, screenshots, and accessibility snapshotting without bundling large browser binaries into your main app.
  • Persistent browser sessions across commands: Enables multi-step workflows where the sandbox persists between sequential command invocations during the automation run.
  • Fast production startup via sandbox snapshots: Uses pre-built Sandbox snapshots (with system dependencies and agent-browser installed) to reduce cold-start time.

Quick Start

Ask your AI to run agent-browser in a Vercel Sandbox microVM to open a URL and return both the page title and a base64-encoded screenshot.

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 automation inside a Vercel app without hitting deployment size limits?▼

You can run headless Chrome automation inside a Vercel app by executing agent-browser commands within Vercel Sandbox microVMs, which avoids bundling large browser binaries into your main deployment and isolates the environment.

Can I take screenshots and capture accessibility snapshots on Vercel using Next.js or SvelteKit?▼

Yes, you can capture screenshots and accessibility snapshots by running headless Chrome inside Vercel Sandbox microVMs, supporting frameworks like Next.js, SvelteKit, Nuxt, Remix, and Astro for server-side tasks.

How do I execute multi-step browser form interactions across persistent sessions on Vercel?▼

You can execute multi-step form interactions by creating a Vercel Sandbox microVM that maintains a persistent browser session across sequential agent-browser command invocations during the automation run.

Do I need the @vercel/sandbox SDK and Vercel credentials to start an isolated browser session?▼

Yes, starting an isolated browser session requires the @vercel/sandbox SDK and Vercel credentials via OIDC or VERCEL_TOKEN, VERCEL_TEAM_ID, and VERCEL_PROJECT_ID to create, run, and stop microVMs.

What is the best way to reduce cold-start time for headless Chrome in Vercel Sandbox?▼

The best way to reduce cold-start time is to use an optional pre-built AGENT_BROWSER_SNAPSHOT_ID, which restores a Vercel Sandbox microVM with system dependencies and agent-browser already installed for sub-second startup.

Why use Vercel Sandbox microVMs instead of running browser automation directly in my server environment?▼

Using Vercel Sandbox microVMs prevents polluting your main server environment with browser dependencies and bypasses local binary size limits, spinning up on demand and shutting down safely after automation completes.
