Why Mateu

Traditional business applications usually require:

• backend logic
• frontend app
• API layer
• duplicated models
• duplicated validation
• a lot of glue code

Mateu takes a different approach:

• one application model
• one source of truth
• less code
• fewer moving parts

Example (real admin panel)

With Mateu, this:

enum ProductStatus {
    Available, OutOfStock
}

record Product(
    @NotEmpty String id,
    @NotEmpty String name,
    @NotNull ProductStatus status
) implements Identifiable {}

@UI("/products")
public class Products extends AutoCrudOrchestrator<Product> {
}

becomes:
