| description.long | A modern Java framework designed to reduce startup time and memory overhead through compile-time optimization rather than runtime reflection, providing built-in support for dependency injection, aspect-oriented programming, cloud-native patterns, and microservice infrastructure. | A framework for creating stand-alone, production-grade Spring applications with minimal configuration. Features embedded web servers (Tomcat, Jetty, Undertow), opinionated starter dependencies, automatic configuration, and production-ready features such as metrics and health checks. |
