While ago I found a great way to Test out a newer versions of Node-Red or just to test out a Node I was not to sure about without installing anything on to my own hardware.
I started to use https://katacoda.com/
Training Platform for Software Engineers.
It's basically a completely free and no signup web browser VPS. And it will last about 1hr. before it stops working. Lots of time to test things out.
Give it a try. Go here.

Then install Node-Red. how about the New Beta Version?
sudo npm install -g --unsafe-perm node-red@next
Or just the Current version
npm install node-red
Once installed you will notice a "+" in the top part of the terminal called "Web preview" click that and
enter the Node-Red port "1880" and there you go all done.
This has to be one of the fasted and easiest way to test out NR or almost anything else out on Ubuntu. For Free.
Happy Testing..
