Proper backends·sutro.xyz

Sutro adds production-grade backends to vibe coding platforms, including data models, actions, security rules, and async workflows. It introduces SLang, a language for concisely defining and deploying backends, and automatically derives schemas, APIs, validation, and internal wiring from domain entities. It also offers prompt-to-full-stack app generation and Figma-to-code conversion, with infrastructure, deployment, and scaling handled automatically.
