Best Serverless Frameworks for Node.js in 2026

TL;DR

SST for full-stack TypeScript on AWS; Serverless Framework for multi-cloud legacy deployments. SST (~200K weekly downloads) is the modern TypeScript-first framework that deploys to AWS with live function development, type-safe resource binding, and a growing ecosystem. Serverless Framework (~2M downloads) is the older multi-provider tool with thousands of plugins. AWS CDK (~500K) is AWS's official infrastructure-as-code with full TypeScript. For new AWS-native apps in 2026, SST is the compelling choice.

Key Takeaways

• Serverless Framework: ~2M weekly downloads — multi-provider, 1K+ plugins, widely deployed
• SST: ~200K downloads — TypeScript-first, live Lambda dev, resource binding, AWS-native
• AWS CDK: ~500K downloads — low-level AWS infrastructure, TypeScript/Python/Java
• SST v3 — Ion release uses Pulumi under the hood, faster deployments
• Local development — SST live lambda lets you test against real AWS services instantly

SST v3 (Modern AWS)

// sst.config.ts — TypeScript infrastructure
import { SSTConfig } from 'sst';
import { Api, Table, Bucket, NextjsSite, Cron } from 'sst/constructs';

export default {

      stack.addOutputs({
        ApiUrl: api.url,
        SiteUrl: site.url,

    });
  },
} satisfies SSTConfig;

// SST resource binding — type-safe, no env vars needed

When to Choose

Scenario	Pick
New AWS project, TypeScript	SST
Multi-cloud (AWS + GCP + Azure)	Serverless Framework
Complex AWS infrastructure	AWS CDK
Legacy Serverless Framework project	Keep SF (migration not worth it)
Full-stack (Lambda + Next.js + DynamoDB)	SST
Need Serverless Console	Serverless Framework
Fine-grained AWS control	AWS CDK
