| 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 Ruby-based framework bundling everything needed for web development: database management, templating engines, email delivery, real-time updates, async job handling, file storage, and built-in protections against common attacks like SQL injection and cross-site scripting. |
