About SST
By Toolradar Team·
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.
