tup proxies services on the local network to a remote gateway, all traffic between the remote server and the service on the local network is sent through a wireguard tunnel
think of tup as an open source and self-hosted alternative to ngrok and cloudflare tunnel
tupd (the server) can be found at: https://drive.proton.me/urls/GEJM1HT0DW#aOop4p7zxaPA
the tup client can be found at: https://drive.proton.me/urls/63SE9PW020#GFzZrprg9wjZ
It is not about leading anything but about having the code in a repository so that it is easy to read/consult/audit/etc.
You can upload the code to any service (it doesn’t have to be GitHub, it can be GitLab, sourcehut, etc…) and disable issues and comments.
