How to test your local web applications in the internet (from different network) without deploying anything.

Actually it is pretty straightforward you just have to download and use ngrok(it’s free):
[program]
https://ngrok.com/
[/program]

In my case I’m using a rails application so I just need to:

# run my server in localhost
rails server
# at this moment it is available in http://localhost:3000 by default
# if you want to test from another network this application go to the path 
# where it is downloaded your ngrok file
./ngrok 3000
# after that I can access my application all over the internet for example:
Tunnel Status                 online
Version                       1.7/1.7
Forwarding                    http://myaccessnumer.ngrok.com -> 127.0.0.1:3000
Forwarding                    https://myaccessnumber.ngrok.com -> 127.0.0.1:3000
Web Interface                 127.0.0.1:4040
# Conn                        0
Avg Conn Time                 0.00ms

That’s it there are a lot of options, for example you can select the subdomain you want!!!
