I don't know if Zeit Now (while really cool!) would work for NodeBB... NodeBB is a web application, and does lots of stuff in the background that relies on a server running. To have a service that spins up whenever a request comes in would be much too slow, if only because that first spin up would take many seconds!
@baris well finally managed to get it working, I was missing to accept merging the branch when doing the pull.... but that was not enough as now it was showing me a problem with the widget essentials... so I checkout the commit for "up widget essentials" and that fixed it for me!!
