Only games uses Nintendo servers, and, as other comments says, Pretendo will replace them. If you’re talking about homebrew apps themeselves, they will not be affected.
I saw someone ask about this the other day. There’s some work on a project called Pretendo that’s designed to work as an open source replacement for the 3DS and Wii U online services. It’s not fully up and running yet but you can see where they’re currently at on the site.
It means all online Nintendo service will be unavailable for the 3DS and the Wii U.
So, the eShop and online game servers will shut down. You won’t be able to purchase any game digitally, and online multiplayer in games will not work. Neither DownloadPlay, probably, but I’m maybe wrong there.
Homebrew, fortunatelly is not provided through any of these channels and they are not dependent on any online Nintendo service.
I haven’t been here on the 3DS scene for awhile, but if there isn’t already, there will likely be homebrew replacement for at least the important online services
Just got back from some things, someone’s already done that when I checked it, but good for letting me know! I’ll go through some other communities a little later today and try to get things going there too :)
I don’t think this is the best game ever, but I used to have (and still have actually) this homebrew game called World of Sand, in my R4, I found it quite simple and relaxing.
