Hello HN. I live in a third-world country where Internet speeds have historically been very poor and generally expensive. So I built an offline file transfer tool called Feem, that helps you transfer text, files and folders between your devices without passing through the Internet.

Warpinator doesn't work on my network so I use feem.io on windows to transfer things over to the deck itself then copy and paste it over to the sd card once its on there (the free version transfers it over to the documents folder).

At $work we instantiated a lufi instance (in DMZ, subdomain DNS record, reverse-proxied) in order to allow our users / developers / projects managers to share files with our customers, just giving to them an HTTPS link. This solution may respond to your needs, too. Source: 12 months ago

I have spun up Gokapi - which works a treat. However it requires a login - so is great for files going the other way.
