+and https://github.com/spring-projects-experimental/spring-fu/tree/main/kofu[KoFu] (Kotlin DSL) designed to configure
 Spring Boot explicitly with code in a declarative way with great  discoverability thanks to auto-complete.
 It provides fast startup (40% faster than regular auto-configuration on a minimal Spring MVC app), low memory consumption
 and is a good fit with https://www.graalvm.org/docs/reference-manual/native-image/[GraalVM native] thanks to its (almost) reflection-less approach.
