From the developer:
Port2 is an essential productivity tool for developers that exposes your local port to the Internet. Therefore, the app helps you turn your local web into a public address for easily accessing by mobile terminals and partners. It can map the public network API address to facilitate debugging by WeChat, payment, webhook, and partners.
With the support of TCP port mapping, the database can also be accessed on the public network.
