For fun. This is what I do instead of video games. I mirrored some old websites using wget, so it can serve those. I also got a bunch of videos I may want to get over network without downloading anything, and it’s great for that. At least with fancyindex module with Material theme.
It also works as a forward proxy to Navidrome server, also running on my phone, so that I can access it through a URL on same IP:PORT.
