This is going to be a quick post, but it’s still something that I like. I love systemd, and try to (over)use it every time I can. This is one of those use-cases where I can use ngrok to freely demo my app without having to set up a cloud instance or open up a port in my router. The simple usage of running ngrok is fine for simple cases like hosting a minecraft server for an hour, but if you need to run it in the background you’d need a service.
