Hello Everyone, I'm a freelancer and I have a project for an online trivia app (not a multiplayer yet for now). I'll be using Unity for the client side, but I'm having a hard time deciding which Backend technologies should I use considering the goal is to have a large number of users in the future. I was thinking to use MySQL as the DBMS but Im planning not to use Laravel or CodeIgniter with it.

Can anyone recommend some Backend stacks that will be ideal? Kudos and Thanks in Advance!

Hi all, I need to create a simple IoT interface application that connects the end device API with a GeoTab API. I am considering using Bubble due to its simple interface and configuration tools, but I fear it's too simple. We will want to add features and new devices as we grow - I was thinking of using CodeIgniter or CakePHP on a hosted site for the application. Must support JCOM encoding between the two APIs and there is no need for a separate interface as GeoTab already has one; we are just connecting and pushing data. Thoughts?
