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

Short summary

AWS Blocks is an open-source Infrastructure-from-Code framework (June 2026) where TypeScript backend code auto-generates AWS infrastructure, positioning between Amplify Gen2 (frontend-first) and App Studio (no-code). It provides 20+ composable Blocks—KVStore, Database, Auth, Agent, KnowledgeBase—that map to DynamoDB, Aurora, Bedrock, and S3 with type safety flowing end-to-end to web and mobile clients. Unlike alternatives, Blocks targets backend developers seeking explicit control and AWS best practices without separate infrastructure configuration.

• •Infrastructure from Code (IFC): Define backend infrastructure directly in TypeScript; no separate infrastructure files or configuration
• •20+ composable Blocks map to specific AWS services (DynamoDB, Aurora Serverless, Bedrock, S3 Vectors, etc.); type safety extends to client code across 9+ frameworks
• •Positioned between Amplify Gen2 (frontend-first, TypeScript full-stack) and App Studio (no-code, visual builder) for backend-centric teams
