title: Which one is better to user between Parse, Firebase and AWS Cognito?
body: <p>I am willing to use synchronisation service for my application. But I want to choose the best one. I want to know which one is better among all these. My application will run on Android , IOS , Windows and Web. </p>
  
  <p>I am going with Firebase because I tested it. It is giving me fast results and it is also allowing me to work offline. Is it better or I will go with Parse or AWS Cognito?</p>
  
  <p>I Also have an option of Google Cloud. Does Google Cloud provides service like Firebase? And are realtime updates possible with Parse as like Firebase?</p>
