Yeah what I ended up doing was just writing plain HTML files directly in a text editor and hosting everything as plain old static files on my Synology NAS on my home internet connection. Works fine for what I need.
May as well push them up to Github Pages. It's free, source controlled, won't go down if you get a spike in traffic, and most importantly doesn't expose your Synology NAS to the internet which has resulted in many security compromises over the years.
