| description.long | Quarkus is an open-source framework that enables Java developers to build cloud-native applications optimized for containers and Kubernetes. It provides rapid startup, minimal memory consumption, and accelerated development cycles through live code reloading, while supporting both imperative and reactive programming paradigms. | 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. |
