Quarkus Vs Spring Boot: a Comprehensive Guide for CTOs in 2023

With the revolution of Microservices, enterprises have seen a rush to migrate their monolithic applications toward microservices. This has put microservices in demand for building modern enterprise applications,  as it reduces complexity and is easy to develop.

There are many microservice frameworks available in the market, where Java provides two outstanding frameworks, Spring Boot and Quarkus, both are popular in their individual zone. In this article, you will see the in-depth comparison of these two frameworks, followed by features, performance, market trends, and their importance, through which it will be easier to decide on a framework between Quarkus vs Spring Boot for app development.

Now, let’s start!

What is Quarkus?

Quarkus is an open-source Kubernetes native Java-based framework, which is mostly used for building cloud-native environments; it supports different programming languages such as Java, Scala, and Kotlin. However, it is mostly used for Java application development using Dockers and Kubernetes. Another important thing is it supports building Java microservice applications.

Basically, Quarkus was designed in 2019 to perform operations with Java libraries, through which running Java applications becomes easier. It also provides dependency and setup for Boot applications.

Features of Quarkus

Live Coding

It provides automatic coding deployment with proper implementation in a container in less amount of time but removes the traditional process that takes much longer time in application development.

Continuous Testing

DEV tools play an important role in continuous testing, implementing the command line for the development of the application, and removing unwanted tools.

Reactive Programming

Reactivating programming and Imperative are essential for microservice development. This programming has become more accessible for creating cloud-native applications.

Support of OpenJDK HotSpot and GraalVM

OpenJDK HotSpot and GraalVM provide the experts with compile code so they may not use JVM. Thus the consumption of resources is reduced for Kubernetes and Quarkus applications and runs as a native Linux executable.

Zero Configuration

While creating or testing applications, Quarkus offers dev services through which it makes an instant start and configures the database.

What is Spring Boot

Spring Boot is known for its scalability and robustness. It is a Java framework, an open-source mostly used for monolithic and microservice applications. Spring Boot is also supported by Groovy and Kotlin. It has some outstanding features that suit building microservices architecture.

It provides high security and design patterns for securing the applications, mostly used for handling high traffic. It is supported by the Java community, which allows solutions to the application’s errors and issues.

Features of Spring Boot

Admin Support

Spring Boot offers a way to turn on administration-related features for the program. It is used to view and manage applications remotely. It can be activated by just changing the Spring application admin and enabled property.


Spring Boot security provides numerous features to protect Spring Boot applications. Applications built with Spring Boot use the Spring Framework. All HTTP endpoints enable basic authentication, making a safe point for one application. To secure an application, a wide range of Endpoints are available.


Spring Boot Autoconfiguration supports your applications with new libraries. Autoconfiguration makes it easy to code the integration of spring applications. When you are on a project, it provides an option with dependency. Spring boot annotation monitors and provides an evaluation of the application.

Web Development

The development of web applications is well adapted for the Spring module. Using Embedded Tomcat, Jetty, or Undertow, through which it can quickly create a standalone HTTP server. Therefore, to make the applications run effectively, using the Spring Boot starters, the web module makes an easy choice to get an effective result.


There are numerous components that Spring Integration offers that can significantly improve the connectivity of systems and processes within a business architecture. Spring Boot integration delivers outstanding functions for application management.

Detailed Comparison for Quarkus Vs Spring Boot


  • Quarkus implements Microprofile API for the Microservice architecture
  • Provides a way to built-in front-end applications
  • The Speed it provides is Faster
  • The utilization of memory for Boot is very less
  • Quarkus is supported by Hibernate for further acceleration
  • For security purposes, Quarkus uses Elytron Security

Spring Boot

  • Spring Boot implements its own module for the Microservice architecture
  • It depends on the Spring MVC and how strong a foundation it builds
  • The speed of the Spring Boot is a little slower than Quarkus
  • The utilization of memory in Spring Boot is more than in Quarkus
  • Spring Boot is developed on Spring
  • Spring Boot uses Spring Security.


Quarkus and Spring Boot are both outstanding performers in their individual roles. However, Spring Boot is known for its maturity, mostly used for monolithic applications and microservice applications, whereas Quarkus is leveraged for cloud and serverless contexts. Now choosing a framework deepens your project requirements. Based on that, you can make a solution. However, if you are finding it difficult to choose a framework you can take a consultation and you can hire Spring boot developers or Quarkus developers.
