Ngrok is a tool that allows you to test locally running web applications using a real ‘live’ URL on the internet.
There are two main use cases that I’ve found which are useful:
- When you want to show a friend something you are working on locally without spinning up a server.
- When you need to test some automated integration e.g. webhooks or micropub integration.
Ngrok offers a basic free package and a paid service. You’ll need to sign up and register for an account before you can use their service locally.
