For what its worth, this has been swiriling around on socials and i saw someone noted that the guy had been busted for something at age 17, maybe he was on some list?
I think this is the most popular GH: https://github.com/anderspitman/awesome-tunneling. There are tunneling tools written in Go, Rust, Python, Node, PHP, Java, .NET, and C. Some use SSH, some WireGuard, some WebSockets, some QUIC, some roll their own protocol. Many are single-maintainer projects with bursts of commits followed by silence.
ngrok owns the space, allows you to actually put protections in place for your tunnel. Really popular for site-to-site vpn replacement and remote access for devices. They have static domains on free now. Tunnels no longer time out.
Cloudflare has a tunnel product, if you're already using their DNS.
With nd, developers shouldn’t need to know how to build or deploy a service; they just need to know what service they want to interact with, and nd helps whether go, webpack, bazel, or docker builds that service. Likewise, deploying a service automatically checks if it was built, and if not, nd will build it for them (or warn them if it's production-bound and they want a CI build instead).
