For myself, the thing that impresses me most about the LocalXpose service, is that it is plug-n-play. I did not have to configure the ISP's router to open any ports, didn't have to turn off or limit the macOS firewall, didn't have to open Mullvad VPN to local traffic or configure it in any other way, didn't have to approve more than 3 connections in Little Snitch. These are the "pain points" that I've encountered in the past with apps of this nature. These simple benefits/capabilities of LocalXpose could be expressed on the landing page, as I'm sure others have experienced similar pain as well.
Another feature is one can install LocalXpose using Homebrew. It is my preferred app/command manager, as I am sure also with other macOS users. The fact that you can install/setup LocalXpose and have a tunnel serving https, file browser, and many other services simultaneously in mere seconds/minutes is a benefit that could be expressed also.
I will be signing up for the "PRO" plan as I've already seen the potential usefulness for my business, study and personal needs.
Well done, indeed!
