Quarkus versus Spring: Full Comparison
I have been developing for a long time with Spring Framework. Lately we started to set up our new projects with Quarkus and in the beginning I was a bit careful about that but over time I really loved it!
Quarkus Framework
It is created for cloud-native and serverless environments and optimized for Kubernetes clusters. With its very rapid startup time, low memory usage, microservice oriented Architecture Quarkus becomes favorite of Java Developers. Dev Experience in that sense is very good because of live reload, fast feedback loop, and programming joy. It also supports native image generation with GraalVM, resulting in faster startup times and lower memory usage. Quarkus has relatively smaller ecosystem compared to Spring, but it is growing rapidly with extensions for various technologies. It uses MicroProfile for configuration and standards.
Spring Framework
It is meant to be general-purpose framework for building enterprise applications. Framework itself has slower startup time compared to Quarkus, but is very effective with Spring Boot. It has also higher memory usage, but manageable with optimizations. Spring has a much greater community with vast documentation and ecosystem. With Spring Native there is a possibility for native image generation but not as good as Quarkus. As a configuration…
