Quarkus overview

A brief rundown: Quarkus is an open source Cloud-Native, container-first framework for writing Java applications. It features fast boot time with low memory and seamlessly live reload with zero additional configuration.

In our Java retrospective series, experts recommended it as one of the top frameworks for Java devs. Don’t just take our word on it, here’s what one of the experts has to say about it:

Definitely Quarkus. The community has developed a great tool to optimize common Java paradigms for the JVM and even the GraalVM native image – this has affected many projects for which Quarkus has dependencies. That they are currently working on becoming officially MicroProfile compatible makes me personally very happy. The website of our Java Usergroup Mainz has now been running on Quarkus for several months without any problems, and that as a native image.

We aren’t the only ones singing its praises. Quarkus won the 2020 DEVIES award for Best Innovation in: Code Frameworks/Libraries.
