Most of these have fallen on their faces because they can't get sufficient adoption rates, and a big part of that is because they refuse to acknowledge that 90%+ of the desktop computer market isn't running Linux or BSD.
Some of them include a half-assed attempt at a Windows client and few if any support MacOS despite it having something like 20-30% of the desktop market
OpenZiti underpins the private connectivity from zrok, another opensource project and is one of the ones that is __not__ riding on wireguard which many people think is a good thing, but sometimes people are interested in a wireguard-based approach.
There is a huge list of alternatives as well you can find at https://github.com/anderspitman/awesome-tunneling. You can find OpenZiti and zrok on there but the github urls if interested are https://github.com/openziti/ziti and https://github.com/openziti/zrok
Zrok seems nice. Right now I use LocalSend to share files between some of my devices, but it is not encrypted at all IIRC, and as the name suggests, it is only "local".
I wonder how zrok compares to OnionShare.
