Sutro

Sutro transforms backend development by letting you describe your system requirements in natural language, which the platform then compiles into a complete, production-ready backend. Rather than scattering authentication rules and API definitions across multiple files, you specify your domain structure once and the platform generates everything automatically. It combines a specialized language called SLang with AI-powered code generation.

Highlights

• Prompt to backend: describe your requirements and get a deployed system ready to use
• Unified definitions: place authentication rules and data models in one spot that automatically propagates to all generated APIs
• Zero infrastructure: generated backends deploy immediately without separate server configuration
• 12x less code: SLang's design cuts boilerplate compared to traditional backend frameworks
• Design to code: generate backends from Figma mockups and natural language descriptions

Ideal for development teams building web and mobile applications who want to ship backends fast without managing infrastructure or repetitive endpoint definitions. Sutro starts with a free trial month, then offers straightforward per-backend pricing that scales with your needs.
