Proper backends.

Add production-grade backends to your vibe coding platform - complete with data models, actions, security, and async workflows.

Introducing SLang

A new language for concisely defining, and effortlessly deploying production-grade backends with Sutro.

Data model

Data model

Data model

Backend structure,
defined just once

Entities describe your domain and relationships - which automatically derive schemas, APIs, validation, and internal wiring.

Authentication

Authentication

First-class security,
enforced by design

Auth rules live next to domain logic, so secure behavior is applied consistently across the backend - not re-implemented per endpoint.

Descriptions

Descriptions

Documentation that doesn't drift

Descriptions are part of the backend definition, keeping documentation, reasoning, and generation in sync.

Actions

Actions

Logic without plumbing

Actions define what your backend does - without repeating validation, auth checks, retries, or async glue.
