How do I host my ASP.NET localhost website through a tunnel to a public URL without timeouts for free?

Question

I'm integrating the HelloSign eSignature API into my ASP.NET website in Visual Studio 2015. I am required to enter a domain/callback URL when creating a test app ( https://app.hellosign.com/api/documentation ).

I used Ngrok for my test app and got everything working, however, I need to consistently generate a new callback link and I would have to change all the links in the HelloSign app settings as well.

Are there any alternatives that I can use to tunnel my localhost (with port number) to a public URL permanently without paying?

I think you are trying to get Dynamic DNS set up. This one Free DNS might do the trick. Take a look and let me know.

To keep the local application going, you can build a C#.NET windows service to run the command in the background. This way it would automatically restart at reboot of the system.
