A few days ago, I started my vacation, and what better way to spend my time than to program a new feature. I wanted to continue learning more about Elixir/Phoenix, so I decided to add the ability to expose your localhost to the Internet (in the same way that ngrok tunnels works) to my side project.
The CLI is in Rust, a language I didn't have much experience working with, but I managed to pull it off.
By the way, the tunnels are free; only tunnels with a static domain require a paid plan.
