I was using filebrowser for few years and it is decent and very usable. Not a lot of features but I think that is a good thing. What I love about it is that it just works on regular plain files and directories - everything can interface with that. can recommend would run again

Good call out on Filebrowser. You can easily start up with brew on macOS and you’re off to the races. Like you said it’s simple and is specifically made to be simple.
