Things that just work and are delight to use and the AWS Amplify CLI are not often mentioned together. The Amplify CLI is a growing collection of poorly thought out, poorly implemented functionality that looks good in demos, but falls apart under any close inspection.
I like Amplify and use it often. However, it isn't well integrated with "normal" backends, so if you want to keep a backend and frontend deployed together you either have to use their Amplify backend API or work out your own deployment.
