Yes, This is similar to Ngrok. Except it is free to use (for now). You log in using your M365 account
We indeed use it to debug our remote event recievers.

      Can you validate that your RER is firing? How did you connect your RER to the list? When using PnP.PowerShell there is a problem of RER's not firing.
      See this post : https://github.com/pnp/powershell/issues/3169

      During debugging you have to attach your RER using the url generated by the devtunnel application.

        These are the steps I used

        I have a WCF RER hosted in my project in folder services\rer.svc
        I host this project local on port 53797
        I push F5 and run the project.
        My service is running at http://localhost:8080/services/rer.svc
        I run .\devtunnel.exe user login and login with my M365 account
        I run .\devtunnel.exe host -p 53797 --allow-anonymous
        I get a devtunnel URL. For example https://gblq14ee-8080.euw.devtunnels.ms
        I attach my rer with this url https://gblq14ee-8080.euw.devtunnels.ms/services/rer.svc
