Why not just use Firefox dev tools?

F12 > click 'Responsive Design Mode' > then click 'Throttling', the options are 2G, 3G, 4G, DSL, Wi-fi.

I guess if you need throttling for something other than a web page, you need something other than a web browser.

Hello,

Yes, you can use built-in dev tool for your browser.

But if you are creating your own application (C++, .NET, JAVA) then you need an external tool like this.
