OpenZiti maintainer (zrok sometimes). It depends on your definitions of peer to peer. the private sharing functionality is peer-to-peer at the application level using a zero trust tunnel, but it'll ride through/over the openziti overlay network (the zero trust part).

If you use the public sharing option, it's definitely "just" a reverse proxy back to your share location without the need to open a firewall hole in your home network. Super useful for plenty of tasks and there are numerous offerings like this.

You can self-host everything yourself if you like or you can use the NaaS version provided by NetFoundry. We operate the zrok/openziti overlay for you in that case. To self-host you would need an openziti overlay network, a zrok controller and zrok front end. It's pretty easy (well, easy for me maybe) overall. People are starting to self-host more and more zrok instances. The software is all strictly opensource and a liberal apache v2 license. You can find them on github:

If you (or anyone) appreciate free, open source tooling like this, don't forget to give the projects a star on github and help spread the word! :)
