SST Has a Free Infrastructure Framework — Deploy Full-Stack Apps to AWS Without YAML

SST (Serverless Stack) is an infrastructure framework for building full-stack apps on AWS — no CloudFormation YAML, just TypeScript.

What You Get for Free

  • TypeScript config — define AWS resources in code
  • Live Lambda — test Lambda functions locally against real AWS
  • Console — web dashboard for managing your app
  • Frontend support — deploy Next.js, Astro, Remix to AWS
  • Databases — RDS, DynamoDB, or Drizzle ORM integration
  • Auth — built-in auth with session management
  • Cron jobs — schedule functions easily
  • Queues — SQS integration with type safety
  • Containers — deploy Docker containers alongside Lambda

Quick Start

npx sst@latest init
Enter fullscreen mode Exit fullscreen mode
// sst.config.ts
export default $config({
  app(input) { return { name: "my-app", home: "aws" } },
  async run() {
    const api = new sst.aws.Function("MyAPI", {
      handler: "src/api.handler",
      url: true,
    })
    return { url: api.url }
  },
})
Enter fullscreen mode Exit fullscreen mode

Why Developers Switch from Serverless Framework

Serverless Framework uses YAML and has limited local dev:

  • TypeScript — no YAML, full type checking
  • Live Lambda — test with real AWS services, not emulators
  • Full-stack — frontend + backend + infra in one framework
  • Modern console — web UI for logs, metrics, debugging

A team maintained 2,000 lines of serverless.yml. After SST: 200 lines of TypeScript, same AWS resources, with autocomplete and type checking.
