1. How to create ngrok local server ?

Introduction

User development machine may be connected to a secure network behind a firewall. To work around access restrictions, ngrok runs a small client process on the user machine which creates a private connection tunnel to the cloud service. Your localhost development server is mapped to a ngrok.io sub-domain, which a remote user can then access. There’s no need to expose ports, set up forwarding, or make other network changes.

The ngrok client software is available for Windows, macOS, and Linux.
