It's impressive how simple the code is: https://gitlab.com/pyjam.as/tunnel/-/blob/main/tunnel.py

All the heavy lifting and reverse proxying is done by Wireguard and Caddy! Very slick.

Though of course all traffic will be ran through pyjam.as. As this isn't a company with an income stream, I fear if its gets too popular it'll be infeasible for the author to keep it up and available for free long term.
