What is AWS Blocks? How it differs from Amplify and App Studio, and what each one is aiming for

On June 16, 2026, AWS announced AWS Blocks as a public preview. It is an open-source framework where the TypeScript you write for your backend becomes the AWS infrastructure that runs it. https://github.com/aws-devtools-labs/aws-blocks The first thing many AWS users will think is "another full-stack tool." If you want a tool for frontend developers to build full-stack apps in TypeScript, Amplify Gen2 already exists. For people who don't write code, there is App Studio. I compared those three earlier in a write-up on App Studio, Amplify Gen1, and Amplify Gen2. Now Blocks joins them. This article organizes what AWS Blocks is from the official docs and the open-source code, lines it up against Amplify and App Studio, and finally sketches a map of what each one is aiming for. Rather than stopping at a feature-diff table, I want to get at why AWS is offering multiple entry points into full-stack development. A note: this is based on the official docs right after the preview announcement
