AWS announces AWS Blocks, an open-source framework for composing application backends on AWS (Preview)

AWS Blocks Public Preview

AWS announces the public preview of AWS Blocks, an open-source TypeScript framework for backend capabilities on AWS without needing to learn infrastructure tools. It provides a local environment with Postgres, authentication, and real-time messaging, no AWS account required. The same code runs on production AWS services with zero changes, and developers can use AWS CDK for direct resource configuration.

What to do

• Run npx @aws-blocks/create-blocks-app to get started.
• Add database tables, user authentication, AI agents, file uploads, and background jobs.
• Test the full stack locally and deploy to AWS when ready.
• Built-in guidance for AI coding tools ensures correct architecture without custom configuration.
• End-to-end type safety flows from the data schema to the frontend without a code generation step.
