You should go for using it in particular if you are going to be build code once run everywhere kind of things and you want to not write most of the backend on your own. As AWS Amplify can take care of a lot of backend things for you and you can manage most of the stuff from front end coding. perfect for using in react/ flutter apps. Additionally better to use when you are going to use other AWS service and don't want to scatter things around
I recommend using Bubble.io for most web applications, including SaaS platforms, marketplaces, e-commerce, social media platforms and much more. While Bubble.io does a lot well, it could do a better job at processing/creating data faster. So if you have a heavily intensive application where you need to create and pass around millions of rows of data in short amounts of time, it might be worth looking at other backend systems to use.
Its AWS take on the Firebase kind of system for providing backend as a service. Although Firebase has advantage of bigger community, better documentation and code examples; AWS Amplify is creating its own space where you will be going to use AWS products and Infrastructure in your project. Amplify Dynamo DB and GraphQL have clear cut advantages that have no direct alternative in Firebase as real time db and firestore documents both lack versioning.
