## What it is
untun is a Node.js CLI and library that exposes a local HTTP(s) server to the internet via Cloudflare Quick Tunnels (cloudflared). It provides both a one-command CLI (`npx untun tunnel`) and a programmatic `startTunnel` API.

## Use cases
- expose a local dev server to the internet
- share a localhost URL with teammates for testing
- test webhooks against a locally running server
- demo a local app without deploying it
- programmatically create a public tunnel from Node.js code

## When to choose
- you need a quick, zero-config public URL for a local server
- you want a Node.js API to manage tunnels inside your tooling
- you already use the unjs ecosystem (e.g. listhen) and want integrated tunneling

## When to avoid
- you need stable, permanent tunnel hostnames or access control (use Cloudflare Tunnel proper or ngrok)
- your project is not Node.js-based and you can call cloudflared directly
- you cannot accept Cloudflare's terms of service
