Features

Everything you keep rebuilding, generated for you

Stop scaffolding the same backend over and over. Focus on the parts that make your product unique.

Full CRUD APIs

Models, controllers, services and routes generated for every entity — consistent and idiomatic.

Auth built-in

JWT with refresh tokens, bcrypt password hashing and route guards, ready out of the box.

Pagination & search

List endpoints ship with pagination, filtering, sorting and search by default.

Swagger & OpenAPI

Interactive API docs and an OpenAPI 3 spec generated alongside your code.

Clean architecture

A layered, modular structure that scales — routes → controllers → services → models.

Validation & tests

Zod or Joi validation on every write, plus unit-test templates and seed data.

FAQ

Frequently asked questions

SQL DDL, a Prisma schema, one or more Mongoose schemas, or a plain-English description of your product. The generator detects entities, fields, relationships, enums and indexes automatically.

No. Without a key the app runs in mock mode and produces a complete, coherent project locally so you can explore the whole experience. Add an OPENAI_API_KEY to unlock full AI generation via the OpenAI Responses API.

Models, controllers, services, routes, middleware, JWT auth with refresh tokens, request validation, centralized error handling, pagination/filtering/sorting/search, Swagger/OpenAPI docs, unit-test templates, seed data and a thorough README.

Express and Next.js API routes today (NestJS is coming soon), with PostgreSQL, MySQL, SQLite (via Prisma) and MongoDB (via Mongoose). The architecture is designed so FastAPI, Laravel, Spring Boot and more can be added without a rewrite.

Yes. Browse the file tree, edit any file in the Monaco editor, copy individual files or everything at once, and download the whole project as a ZIP.

All input is validated with Zod, untrusted content is sanitized and treated strictly as data to mitigate prompt injection, requests are rate-limited, and generation is behind authentication.
