This server is a simple Node.js app that sends received msg to all browser connected using Socket.io, no muss no fuss. As far I need a quick solution, it assumes it's hosted on Heroku, but it's straightforward to modify to be hosted elsewhere.
Create a new heroku app:
Note down the name of app (i.e hollow-galaxy-7080)
git push heroku master
Connect to server:
Send a message using provided script:
./send.sh hollow-galaxy-7080 'message log'
