Your models in.
Plain Spring Boot out.

Graada reads the models your system is already described in and generates standard Spring Boot code from them. Any Spring developer can maintain the result, without learning the language it came from.

Your modelExample in JHipster JDL

entity Customer {  name String required  email String required unique  phone String}

CustomerBase.javaGenerated, rewritten on every run

// Source: model.jdl, entity Customer@MappedSuperclasspublic abstract class CustomerBase {     @Column(nullable = false)    private String name;     @Column(nullable = false, unique = true)    private String email;     private String phone;     // getters and setters}

Customer.javaWritten by your team, never overwritten

@Entitypublic class Customer    extends CustomerBase {     // Your business rules live here.    public String displayName() {        return getName()            + " <" + getEmail() + ">";    }}

Change the model and run the generator again. The generated class is rewritten; the class your team wrote stays exactly as it was.

What you get

Plain Spring Boot: JPA entities, repositories, REST controllers, JMS listeners, scheduled jobs and a Maven or Gradle build, on Spring Boot 4 and Java 25. There is no proprietary runtime underneath.
Contracts that hold: Your public API is captured as OpenAPI and AsyncAPI specs before anything moves, and the generated code is tested against them.
Safe regeneration: Generated classes and hand-written classes live in separate files, so running the generator again never erases your work.
A source for every file: Each generated file points back to the model element it came from, so every line can be audited.
No copyleft surprises: What you ship carries no GPL dependency unless you decide to include one.

One generator for many modelling languages

Each modelling language gets its own importer. Every importer writes the same shared model, and one generator turns that model into Spring. Supporting another language, including your own in-house DSL, means writing an importer, not new Spring templates.

How a migration runs

We read your models and your public contracts. Your existing system stays the reference until the new one matches it.
We agree a mapping. Every concept in your language gets a Spring target. Where none exists, the generator leaves a marked extension point for your team instead of guessing.
We generate, then test against your contracts. Endpoints and messages must behave as they do today.
You get a standard Spring Boot codebase. Any Spring team can maintain it, and it can be regenerated whenever your models change.

Graada does not turn edited Spring code back into your modelling language, and it does not copy an old runtime class by class. It generates what your models describe and marks everything else for a person to write.
