Amplify Gen 2 vs SST vs AWS CDK for Full-Stack TypeScript on AWS

AWS Amplify
SST
AWS CDK
TypeScript
Infrastructure as Code

All three let you define infrastructure in TypeScript next to your application. They sit at different heights. Amplify Gen 2 gives you five opinionated categories (auth, data, storage, functions, AI) and generates the rest. SST gives you components for common building blocks, including frontends, and a fast development loop. CDK gives you every AWS resource and leaves the opinions to you.

Question 1 of 2

Do Amplify's auth and data categories fit your app?

Our verdict

**Amplify Gen 2:** a product team that wants auth and a typed data layer working today, and is happy with AppSync and DynamoDB or an existing SQL database. **SST:** teams that want framework-level conveniences (Next.js and other frontends deployed to their own account, live Lambda development) without Amplify's data model, and are comfortable with a non-CloudFormation engine. **AWS CDK:** platform teams, multi-service systems, anything with real networking, and organizations standardizing on CloudFormation. The most control and the most to decide.
