SST Framework
The SST framework is an open source CLI and component library distributed via npm (`sst`) and as a Go-based CLI. Developers describe their full-stack application in a single `sst.config.ts` file using SST components (e.g. `sst.aws.Function`, `sst.aws.Bucket`, `sst.aws.Nextjs`, `sst.cloudflare.Worker`) plus any of the 150+ Pulumi/Terraform providers. The CLI (`sst init`, `sst dev`, `sst deploy`, `sst diff`, `sst remove`, `sst secret`, `sst shell`, `sst tunnel`, `sst refresh`, `sst state`) drives local development with live Lambda tunneling and production deployment with stage namespacing. The SDK exposes linked resources at runtime so app code never hardcodes infrastructure identifiers.
