Security and documentation
JWT, RBAC, exception handling and OpenAPI documentation are selectable from Pro / Startup. Enterprise options include SSO and attribute-based access control.
NESTJS BACKEND GENERATOR
A NestJS module for every part of your schema.
Generate an organized NestJS API with entity modules, DTOs, services and controllers connected through dependency injection.
TypeScript / NestJS
Architecture you can work with.
Each entity has a module that groups its controller, service and data model. Nest’s dependency injection wires the application together.
Choose NestJS when you want module boundaries and dependency injection in a TypeScript project. Entity DTOs separate API input from persistence. JWT strategies and role guards integrate with the Nest request lifecycle when security is selected.
Database integration
TypeORM is configured through the application module, with a standalone data source for migration tooling. PostgreSQL, MySQL and MongoDB have database-specific entity output.

WHAT YOU GET
A foundation, with the pieces connected.
Generate models, data access, a service layer and CRUD endpoints from tables and relationships. Add application-specific business rules to the source you download.
Deployment and operations
Dockerfiles are available from Pro; Team adds Redis caching and tracing. Agency Scale adds Kubernetes manifests, Helm and CI/CD configuration. Review secrets, infrastructure and tests before deploying.
Source you can extend
Single-module projects keep the initial structure straightforward. Eligible plans can separate the contract and implementation into modules within one deployable application.

Less setup.
More application.
From an existing schema or a structured requirement to a project you control.
- 01
Upload a schema
Start with SQL or describe your requirements. Review the structured schema, tables and relationships.
- 02
Choose your configuration
Select the stack, database and architecture. Add the capabilities available in your plan.
- 03
Generate. Download. Build.
Generate the source, download your project and configure it for your environment. Extend it with your business logic.

Natural-language input is structured before generation. The backend source is generated deterministically.
NestJS output groups entities into modules and uses dependency injection, decorators and guards. The Node.js option uses Express routes and middleware directly. Both generate TypeScript.
