Ngrok configure multiple port in same domain

Is it possible to open multiples ports in ngrok in same domain?

Something like:

Fowarding http://example.ngrok.com:50001 -> 127.0.0.1:50001

Fowarding http://example.ngrok.com:50002 -> 127.0.0.1:50002

I´m working in windows and it'll be useful for debuging with IIS Express

Yes, it is possible using multiple simultaneous tunnels, within the same hostname !

All you need to do, is to declare them on your configuration file, like this:

authtoken: 4nq9771bPxe8ctg7LKr_2ClH7Y15Zqe4bWLWF9p
tunnels:
  first-app:
    addr: 50001
    proto: http
    hostname: example.ngrok.com
    host_header: first-app.example.ngrok.com
  second-app:
    addr: 50002
    proto: http
    hostname: example.ngrok.com
    host_header: second-app.example.ngrok.com        

And run them with:

ngrok start --all

Look on the documentation for options, like hostname, subdomain, authtoken and host_header. Hope this help you !

P.S For Free plan remove custom host and header part like this it will be different domains FYI.

authtoken: 6yMXA63qefMZqCWSCHaaYq_5LufcciP1rG4LCZETjC6V
tunnels:
  first:
    addr: 3002
    proto: http    
  second:
    addr: 8080
    proto: http

NOTES:

• To find your default config file read https://ngrok.com/docs/ngrok-agent/config/.

• All plans issues an auth token. You can find yours in the web dashboard: https://dashboard.ngrok.com/get-started

Update: Nov 2024

for version 3, you need to do the following:

version: "3"
agent:
    authtoken: 2pNn6oWWEWEsdasc7xveBp2Q1TaPpl_3Jut8L2p4wCsdfEEF9BEcUk
      
tunnels:
  score_api:
    proto: http
    addr: 8000
  weather_api:
    proto: http
    addr: 9801
