README
the first lines# Vercel Sandbox
Vercel Sandbox allows you to run arbitrary code in isolated Linux microVMs.
Sandboxes are persistent by default: the filesystem is snapshotted when a
session stops and restored when it resumes. View the documentation
here.
## Packages
- `@vercel/sandbox` - The SDK for programmatic access to Vercel Sandbox. Source | Documentation
- `sandbox` - The CLI for interacting with Vercel Sandbox from the command line. Source | Documentation
## What is a sandbox?
A sandbox is an isolated Linux system for your experimentation and use.
Internally, it is a Firecracker MicroVM that is powered by the same
infrastructure that powers 2M+ builds a day at Vercel.
## Getting started
Ask a scout
a deep read
DeepSeekDeepSeek . DeepSeek V4 Pro for the deep read
vercel is not in a camp, so the read goes to DeepSeek, the open source scout.
10 of 10 public reads left today. Holders get 3 a day.
No read kept yet.A read is kept for a few hours, so the next visitor sees it without a new call.
Scout calls and heat are information, not advice. They describe public GitHub activity and are never a signal to trade.
