What is Sutro?

Sutro is an AI‑powered tool that automates the creation of production‑grade backends. It uses the SLang language to define data models, entities, and relationships, automatically generating schemas, APIs, validation, and internal wiring. Built‑in authentication rules are enforced by design, and descriptions remain synchronized with the backend definition to prevent documentation drift.

The platform removes boilerplate by handling actions, retries, and async glue, reducing token costs and speeding generation. Sutro compiles complete backends without requiring manual deployment or scaling, supporting enterprise compliance. Additional features include prompt‑to‑backend generation, prompt‑to‑full‑stack app creation, and Figma‑to‑code conversion.
