What is Sutro?
Sutro is an AI-powered platform that enables users to create production-grade backends and full-stack applications instantly without writing any code. It combines LLM-powered AI with proprietary compiler technology to generate mobile and web apps from a single text prompt. The platform offers two main approaches: Studio (a visual no-code interface) and SLang (a dedicated programming language for defining backends), making it accessible to both non-technical entrepreneurs and developers who prefer code-based definition.
Key features include production-grade backends with data models, actions, security rules, and async workflows. Studio allows users to visually define entities and their relationships, add business logic, configure security rules, and see changes take effect immediately. SLang provides a concise language for defining entities (database schema and relationships), actions (reusable business logic), triggers (API endpoints, cron jobs, queues), and role-based access control baked into the core. The platform automatically derives schemas, APIs, validation, and internal wiring from entity definitions.
Sutro is designed for entrepreneurs, founders, businesses, and developers who want to launch production-ready software faster without getting bogged down by technical complexities. It targets users building MVPs, scaling businesses, and anyone needing custom software that grows with their business. The platform supports publishing to web, iOS, and Android, with modular APIs that help expand AI app builder capabilities. Over 20 years of combined experience on code-gen engines backs the platform's reliability.
The platform handles hosting, AI expertise, product management, design, compiling, and scaling under the hood. Users can make high-level changes easily (like adding ratings to posts) without low-level drag-and-drop work typical of no-code platforms. It supports custom code, custom components, and custom integrations, with the ability to continue editing, maintaining, and upgrading apps after publication.

Frequently asked questions about Sutro
What is Sutro and what does it do?
Sutro is an AI-powered platform that enables businesses and entrepreneurs to create custom software instantly without writing a single line of code. Its LLM-driven app builder instantly creates apps from a single text prompt, generating web, iOS, and Android clients along with production backends. The platform combines AI power with a flexible no-code approach to launch production-ready software faster than ever.
How do I start building with Sutro?
You can start building in two ways: Use Studio to create backends visually without writing code, or write your backend definition in SLang and upload it to Sutro. For Studio, visit Sutro Studio to see an intuitive interface, define entities and relationships, add actions and business logic, configure security rules, and publish directly. For SLang, you need jq and curl tools plus a security bundle downloaded from the Sutro Console during onboarding.
What is SLang?
SLang is the programming language for defining Sutro backends. It provides a simple but powerful way to cleanly and intuitively define entire backends including entities, logic, and security without boilerplate or complex syntax. SLang is designed around four primary constructs: Entities (database schema and relationships), Actions (reusable business logic functions), Triggers (entry points like API endpoints, cron jobs, queues), and Security (role-based access control baked into the core).
What is Sutro Studio?
Studio is the simplest way to get started with Sutro, offering a visual interface to create and edit backends without writing any code. In Studio, you can define entities and their relationships, add actions and business logic, configure security rules, and see changes take effect immediately. Once satisfied, you can publish your backend directly from Studio, and it will be published automatically.
What platforms can I publish my app to?
Sutro allows publishing to web, iOS, and Android. The Free tier lets you publish to web with Sutro logo. The Launch plan at $99/month includes publishing to web with full-hosted backend. The Grow plan at $249/month includes publishing to iOS and Android plus up to 5 published apps, payments, custom domain, and usage analytics.
Do I need coding experience to use Sutro?
No coding experience is required. Sutro is designed to let users create custom software instantly without writing a single line of code. The LLM-powered AI automatically generates customizable mobile and web apps from a single text prompt. However, users can also enter their own custom code, custom components, and custom integrations if they prefer.
What makes Sutro different from other no-code platforms?
Sutro is not just another no-code platform. Unlike traditional no-code tools where you drag and drop at a low level with lots of work to get anything working, Sutro works like an entire development or product team. Users can make high-level changes without much effort, such as asking to add ratings to posts, and Sutro knows where to add the feature, introduce ranking algorithms, and perform aggregation. It combines AI with proprietary compiler technology.
How does Sutro handle hosting and infrastructure?
Sutro handles all hosting and work under the hood of app building. The platform provides full-hosted backends as part of its services, taking care of infrastructure, inference optimizations, and cost management. Users don't need to worry about underlying infrastructure, cloud orchestration, or inference framework and hardware optimizations. Sutro manages job execution from intelligent batching to all infrastructure concerns.
Can I customize my app's design and functionality?
Yes, Sutro provides a studio toolkit that enables users to customize various aspects of the app, including visual style and functionality. You can change things to meet your needs, including the visual style and other aspects of the app's function and design. The platform also supports custom code, custom components, and custom integrations for additional customization beyond the no-code interface.
How do I get access to Sutro?
You need to request an invite to access Sutro. The platform mentions you can request your invite today and start building in 5 minutes. For self-serve access, customers can access the product themselves in self-serve mode, or they can work in tandem with Sutro's team to develop their apps. During onboarding, you'll download a security bundle from the Sutro Console which includes API client credentials and certificates.
