Better yet would be setting up your own wireguard instance and not relying on free lunches. But as far as free lunches go tailscale would be my preferred option
Lots of different technical solutions for how to do this, including the Claude and ChatGPT mobile apps nowadays. I use Tailscale. Choose what works best for you and enjoy.

Terminus is trivial to use with a rented VPS. But, ptn solves a different problem
Laziness - the mother of (most) invention.
