What I Self Host

There seems to be a fad for "self hosting" things now. What I don't understand is: what happened to just having a single device and having it run the code directly and show you the result directly? For example, why can't the thing that connects to the Spotify API just... do that, from a program that runs locally, independent of a web browser, with a GUI created using a standard non-web GUI toolkit? Why would I want to use it by pointing my browser at a machine name (of another device I own) and port number, rather than by launching a dedicated program?

Others already answered with information that you usually have more devices then just 1. So you can have access to your data from PC, laptop and your phone. I for once also like to have my own data my own. I.e. I have:

- my own email server

- my own files sharing service

- service for cardDav, CalDav etc.

- service for editing my own office files on mobile

- notes that are synchronized

- streaming of movies and music

- build and git server

- my own smart home service

- notification service

- chat

- VPN

- desktop sharing service

- my own DNS for blocking adds

- and others

I tried various Things to be able to access my own DNA while not at home and ended up using wire guard for my subnet so that I always have access to my DNA server. Right now I am solving it with mikrotiks "back to home" app., but the regular wire guard app does it as well. It uses very little battery.
