Controlling Client Variables On The Server

Hey! I want to be able to control variables on people’s clients from a server. I’m currently using Github to update raw code but that takes 5 minutes+ and is unreliable. I tried using firebase but it has pretty low reads when I’m reading alot of info. Anyone got any ideas?

Thanks in advance!

Edit: Found that firebase works really well. Should I be concerned about hitting the 50,000 requests a day limit? My game won’t be that popular and it’ll only be running 1 request every 20 seconds for about an hour on some days, other days it won’t run any requests at all.
