Accesing a URL on localhost from the internet with ngrok

Posted by Brian Porter on May 17, 2020

Have you ever needed to expose a URL from you local development machine to the internet in order to test something, or let someone else take a quick look?

I hate messing with my router, and trying to open up a URL through my firewall or NAT - especially if it is a one time thing for testing.

A friend put me on to ngrok - ( - which sets up one time URL’s while running. There is a free version, but also a professional verison if you want to have more features, like your own domains or regularly using the same URL.


A simple one is setup like this:

$ ngrok http 8080

You can also add a password protection with basic auth like this:

$ ngrok http -auth "user:password" 80

Once it is started, you see information in your terminal, along with a monitoring of requests coming in:
