## What it is
Pierced is DingTalk's official intranet tunneling (reverse proxy) tool that exposes local HTTP services and databases via a public subdomain like abcde.vaiwan.com for development and testing. The tool has been taken offline for security compliance reasons and DingTalk now recommends its Stream mode instead.

## Use cases
- expose a local web server to the internet for webhook testing
- test DingTalk callbacks without a public IP or domain
- tunnel a local MySQL database over TCP for remote access
- share a local dev environment via a public subdomain
- forward local port 8080 to a public URL

## When to choose
- you need a quick temporary tunnel for DingTalk development testing
- you have no public domain or IP during local development

## When to avoid
- the tool is officially discontinued and no longer operational
- any production or formal environment - DingTalk explicitly forbids it
- you need stable, guaranteed tunnels - use ngrok, frp, or Cloudflare Tunnel instead
- you need security compliance guarantees
