maybe i'm being stupid, but what's the complexity behind this? why is this exciting? is it because it's running on memory or because it's running on the pi? i find this trivial unless you're a new engineer.

for the ones that say that the pi can't handle tls that's just stupid. that's trivial as well.

for the ones saying that you need a vps how cloud native are you people? you can just expose a port on your router (if you're brave enough) and have any dynamic dns service point to the correct ip address.
