Firebase is database service that is used to provide backend functionality for applications big and small.
Firebase has three types of plans icluding a free plan that allows you real time data download and upload limits and 
also storage facilities.  Firebase on the free plan allow 100 simultaneous connections to your application.

the link with friends and family and begin to chat provided there are only 100 simultaneous connections. If you are expecting more than 100 simultaneous connections to your app
