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
