Quarkus Features

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.

Unifies imperative and reactive

Combine both the familiar imperative code and the reactive style when developing applications.

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.


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.

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%.

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.
