AWS Blocks: Open-source framework for application backends (Preview)
AWS Blocks, an open-source TypeScript framework, is now in public preview, simplifying backend development on AWS by abstracting infrastructure tools. It allows developers to run a local environment with essential services and deploy the same code to production AWS services without modification. This framework aims to accelerate the development of applications by integrating database, authentication, and AI capabilities with full-stack type safety and built-in guidance for AI coding tools. It supports various frontend frameworks and is available at no extra charge, with deployment across all commercial AWS regions.

- Open-source framework for composing application backends
AWS Blocks is a new open-source TypeScript framework that provides backend capabilities on AWS, allowing developers to build applications without needing to learn infrastructure tools. It enables local development with services like Postgres and authentication, and deploys the same code to production AWS services.
- Integrated local development environment
The framework includes a fully functional local environment that supports Postgres, authentication, and real-time messaging, requiring no AWS account for local testing. Developers can add features like database tables, AI agents, and background jobs locally before deployment.
- Seamless deployment to AWS and CDK integration
Applications built with AWS Blocks can be deployed to production AWS services with zero code changes. Developers can also integrate with AWS CDK at any point for direct resource configuration when needed.
- Built-in AI guidance and end-to-end type safety
AWS Blocks offers built-in guidance for AI coding tools, enabling correct architecture without custom configuration, and provides end-to-end type safety from data schema to the frontend, eliminating the need for code generation steps.
Enhancements (1) ›
- Support for various frontend frameworks
During the preview, AWS Blocks supports popular frontend frameworks, including Single Page Applications (SPAs) like Vite with React, and Server-Side Rendering (SSR) frameworks such as Next.js, Nuxt, and Astro.
Notes (1) ›
- Availability and cost
AWS Blocks is available at no additional charge, with users only paying for the AWS services their application consumes. The framework can be deployed to all commercial AWS regions, and getting started involves running `npx @aws-blocks/create-blocks-app`.
