Everything you'd write by hand — done for you

Every layer of a production Spring Boot 3 API, generated and wired together from a single plain-English prompt.

🏗️
Full Layer Stack
Entity · DTO · Repository · Service · Controller — all wired together, ready to run.
🔗
JPA Relationships
@ManyToOne · @OneToMany · @ManyToMany with join tables, FetchType.LAZY, and cascade.
✅
Bean Validation
@NotNull · @Email · @Min · @Max · @Size — extracted from your prompt automatically.
📄
Pagination & Filtering
JpaSpecificationExecutor + PagedResponse wrapper. Sortable, filterable endpoints.
🗺️
MapStruct Mappers
Generated <Entity>Mapper interface for clean DTO ↔ Entity conversion.
🐳
Docker Ready
Dockerfile + docker-compose.yml with PostgreSQL/MySQL + optional Adminer UI.
🚨
Error Handling
GlobalExceptionHandler · ErrorResponse · ResourceNotFoundException — all pre-wired.
🧪
Test Scaffolding
Generated unit and integration test stubs per entity, ready to fill with logic.
// self-host

Run it your way

Docker, source build, or direct CLI — your choice.

Run locally — three options 
# Option 1: Docker (recommended)
docker run -p 8080:8080 ghcr.io/rrezartprebreza/rest-api-generator:latest

# Option 2: Build from source
git clone https://github.com/rrezartprebreza/rest-api-generator
cd rest-api-generator
./gradlew run --args="serve --port 8080"

# Option 3: Generate ZIP directly from a prompt file
./gradlew run --args="generate-zip --file prompt.txt --out scaffold.zip"
unzip scaffold.zip -d my-api && cd my-api && ./gradlew bootRun
From prompt to project, with less friction.

This tool is built to help you spend less time on repetitive scaffolding and more time on domain logic, architecture, and shipping useful features.

Run it locally, self-host it for your team, explore the generated project, and enjoy building.
