Today, AWS announces the public preview of AWS Blocks, an open-source TypeScript framework for application developers who want backend capabilities on AWS removing the need to learn infrastructure tools. AWS Blocks runs a fully functional local environment with Postgres, authentication, and real-time messaging, no AWS account required. When ready to deploy, the same application code runs on production AWS services with zero changes, and developers can drop into AWS CDK at any point for direct resource configuration.
A developer building a SaaS application can add database tables, user authentication, AI agents, file uploads, and background jobs in a single session, test the full stack locally, and deploy to AWS when ready. Built-in guidance for AI coding tools enables correct architecture without custom configuration, and end-to-end type safety flows from the data schema to the frontend without a code generation step. At preview, supported frontend frameworks include SPAs (e.g. Vite + React) and SSR frameworks such as Next.js, Nuxt, and Astro. AWS Blocks is available at no additional charge. You pay only for the AWS services your application uses.
AWS Blocks deploys to all commercial AWS regions.
