How it works

From blank project to running API in 4 steps

  1. Project info

    Set your project name, group ID, Java version, and Spring Boot version. Same options as Spring Initializr — but this is just the beginning.

  2. Define your resources

    Add your domain entities (tables), their properties and data types. Each resource automatically gets a full CRUD layer: entity, repository, service, controller, DTO.

  3. Define relations

    Link your resources with JPA relationships: @OneToMany, @ManyToMany, @ManyToOne, and N-ary associations. The generator handles cascade, fetch type, and join columns.

  4. Generate & download

    Click Generate. Download a ZIP. Unzip and run mvn spring-boot:run. Your API is live on localhost:8080.

What you get

Every file you need, zero boilerplate to write

Full project structure

Maven pom.xml or Gradle build.gradle, application.properties, main class — ready to open in IntelliJ or VS Code.

Complete CRUD per resource

Entity, JPA repository, service interface + implementation, REST controller with all HTTP verbs, DTO with MapStruct mapper.

JPA relationships

Bidirectional and unidirectional associations correctly mapped. No more hand-writing @JoinColumn or @MappedBy.

Spring Boot 4.x ready

Generated code targets Spring Boot 4.x with Jakarta EE, Java 17/21/25, and Spring Data JPA best practices.

Instant ZIP download

No account, no waiting. The ZIP is generated server-side and downloaded immediately after generation.

Proprietary engine

Built on a custom generation engine — not a wrapper around Spring Initializr. Clean, consistent, predictable output every time.

Developer time saved

Setting up a Spring Boot REST API from scratch takes ~20 hours. We cut that to 2 minutes.

Entity classes, repositories, services, controllers, DTOs, mappers, configuration — that's easily a full working day before you write a single line of business logic. SpringBoot Generator produces all of it in one click.

FAQ

Common questions

Is the generated code production-ready?
Yes. The code follows Spring Boot best practices: layered architecture, DTO pattern, service abstraction, and JPA repository. It's a solid starting point — you take it from there and add your business logic.
Which Spring Boot version does it target?
SpringBoot Generator targets Spring Boot 4.x with Jakarta EE (Jakarta Persistence, Jakarta Validation) and Java 17, 21 or 25.
Do I need to create an account?
No. The free tier requires no account and no credit card. Generate, download, and run — that's it.
What database does it use?
The free tier uses MySQL. The Pro plan adds PostgreSQL as a target database, with application.properties pre-configured for each.
