Hi,
I have deployed a sbws instance that be found on the following URL: https://sbws.lavafeld.org/sbws.bin
It runs on a dedicated hardware with sufficient enough resources to handle a bunch of connections and load.
I also made an ansible role that deploys sbws running as a user and uses Caddy as its webserver, the role can be found here: https://github.com/anadahz/sbws-ansible
Feel free to use it.
Cheers, ~Vasilis
