## Quarkus Benefits

### Developer Joy

A cohesive platform for optimized developer joy with unified configuration and no hassle native executable generation. Zero config, live reload in the blink of an eye and streamlined code for the 80% common usages, flexible for the remainder 20%.

### Performance

Quarkus streamlines framework optimizations in the build phase to reduce runtime dependencies and improve efficiency. By precomputing metadata and optimizing class loading, it ensures fast startup times for JVM and native binary deployments, cutting down on memory usage.

### Kube-Native

The combination of Quarkus and Kubernetes provides an ideal environment for creating scalable, fast, and lightweight applications. Quarkus significantly increases developer productivity with tooling, pre-built integrations, application services, and more.

### Community and Standards

Quarkus provides a cohesive, fun to use, full-stack framework by leveraging a growing list of over fifty best-of-breed libraries that you love and use. All wired on a standard backbone.

### Reactive Core

Built on a robust reactive core, Quarkus ensures fast and efficient performance, supporting the development of a wide variety of modern applications.

### Container First

Quarkus tailors your application for GraalVM and HotSpot. Amazingly fast boot time, incredibly low RSS memory (not just heap size!) offering near instant scale up and high density memory utilization in container orchestration platforms like Kubernetes. We use a technique we call compile time boot.

The live coding fast feedback loop was very useful when developing with Quarkus. Although fast startup was nice, it wasn’t critical since our apps are long-running, but during development, as we tweaked our APIs, being able to immediately re-test saved us a ton of development time.

## Quarkus is part of the Commonhaus Foundation

In order to fulfill our goal of being a more inclusive and fostering a more collaborative environment, we have moved to the Commonhaus Foundation. This is a step to further solidify our commitment to open-source development and enterprise adoption, addressing the perception that it was overly dependent on a single vendor (Red Hat). This move aims to provide a neutral ground where other organizations and contributors can feel equally valued and involved, ensuring Quarkus continues to thrive, supported by a broad base of contributors from multiple organizations.
