what is sst fr?

SST is a deployment framework that makes it easy to build and ship full-stack web apps on your own cloud infrastructure, specifically Amazon Web Services (AWS). Instead of paying a platform like Vercel or Netlify to host your app, SST helps you deploy directly to AWS while handling all the complicated configuration that normally makes AWS intimidating. For vibe coders and founders: if you are building with Next.js, Remix, Astro, or just a plain API backend, SST gives you a command-line tool and configuration layer that automates setting up servers, databases, file storage, and other AWS services. You describe what your app needs in code, and SST provisions it for you. The big advantage over managed hosting platforms is cost and control, AWS pricing can be much cheaper at scale, and you own your infrastructure entirely. A standout feature is "Live" development mode, which lets your local code connect directly to your real cloud resources while you develop, so you get actual cloud behavior without constantly deploying. SST also has a visual Console for monitoring and managing your deployed apps. It supports popular JavaScript and TypeScript frameworks out of the box, so if you are already building with those tools, the learning curve is manageable. There is an active Discord community and good documentation. It is open-source and free to use, you only pay AWS for the actual cloud resources your app consumes.
