What is SST?

Editorial review
SST (Serverless Stack) is an open-source infrastructure framework that enables developers to deploy complete application stacks on AWS through a unified configuration file. Using a single sst.config.ts, developers can define and connect databases, APIs, frontends, and services together. SST natively supports modern frameworks including Next.js and Rails, with integrations for services like PlanetScale and Cloudflare. The platform provides a superior local development experience with live Lambda debugging and fast deployments. Built on AWS CDK, SST offers higher-level constructs for Lambda, API Gateway, DynamoDB, S3, and more. Loved by thousands of teams, SST is 100% free with no licensing fees-you only pay for AWS resources used.

SST FAQ

How does SST facilitate full-stack application deployment?

Which teams would benefit most from using SST?

Teams focused on DevOps, Cloud & Infrastructure, and Hosting & Deployment would find SST particularly useful. It is designed for developers who want to deploy full-stack applications on AWS with a modern serverless framework and good TypeScript support.

How is SST priced?

SST is 100% free to use, with no licensing fees or paid plans required. Users only pay for the AWS resources consumed by their deployed applications.

What kind of local development experience does SST offer?

SST provides a superior local development experience, including live Lambda debugging and fast deployments. This allows developers to iterate quickly and test their applications efficiently before deploying to AWS.

Can SST integrate with other services beyond AWS?

While SST is built on AWS CDK and primarily deploys to AWS, it offers integrations with services like PlanetScale and Cloudflare. This allows for flexibility in connecting to external data sources and content delivery networks.

How does SST compare to AWS Amplify?

SST, like AWS Amplify, is an open-source framework for deploying applications on AWS, but SST offers higher-level constructs built on AWS CDK for services like Lambda and DynamoDB. SST also emphasizes a unified configuration file and provides live Lambda debugging for local development.

What are the main trade-offs when choosing SST?
