When you look at the advanced programming frameworks popular among developers, you will notice that Quarkus and SpringBoot hold prominent places. Let’s understand and compare the two.

The Java ecosystem has been changing fast. Some of the most significant changes have come from the rise of microservices, containers, and cloud computing. We’ve seen many new frameworks and tooling emerge to support these changes.

For example, Spring Boot has become a De Facto standard for Java development. Meanwhile, other frameworks like Quarkus have emerged to fill in the gaps and provide additional functionality.

What is Quarkus?

Quarkus reimagines the Java stack to give the performance characteristics and developer experience needed to create efficient, high-speed applications. It is a container-first and cloud-native framework for writing Java apps.

You can use your existing skills to code in new ways with Quarkus. It also helps reduce the technical burden in moving to a Kubernetes-centric environment. High-density deployment platforms like Kubernetes need apps with a faster boot time and lower memory usage. Java is still a popular language for developing software but suffers from its focus on productivity at the cost of RAM and CPU.

Quarkus Pros and Cons


  • Simple Documentation: Quarkus is more documented when compared to Springboot.
  • Faster: With the build-time metadata processing mechanism and standalone images built with Graal and Substrate VM, Quarkus ensures much faster boot time cutting down the overall app-building cost.
  • Hot Reloads: Quarkus can provide faster hot reloads when compared to SpringBoot.
  • Continuous improvement: It is developed on JAX-RS, one of the new Java specifications.
  • Excellent Up-To-Date Roadmaps: Providing excellent and interesting roadmaps, Quarkus helps developers to improve their projects with every new release.


  • Complicated Installation of GraalVM: Though Quarkus is adapted to GraalVM, its installation process is not beginner-friendly. It requires verification of the OS-specific binaries and packages.
  • Lack of Solution on Forums: There are not enough solutions to some of the problems one can face while using Quarkus on the community forums. It’s because Quarks is a relatively new framework, and it’s getting wider appreciation.

What is Spring Boot?

Java Spring Boot (Spring Boot) is a tool that makes developing a web applications and microservices with Spring Framework faster and easier through three core capabilities: Autoconfiguration. An opinionated approach to configuration. The ability to create standalone applications.

Spring Boot Pros and Cons

Spring Boot Pros:

  • Community Help: Spring Boot has excellent documentation and outstanding community support.
  • Low Costs: Extensive features like auto-configuration, starters, and YAML, support, help developers take care of most boilerplate code and reduce overall cost.
  • Faster I/O Ops: It provides faster I/O operations compared to Quarkus.
  • Outstanding Community Supports: You can virtually find any solution provided by the extended Spring Boot community.
  • Excellent Documentation: Spring Boot has extensive documentation, which can help solve most issues that occurred during development.
  • Security: It is more secure than Quarkus.

Cons of Spring Boot:

  • Time Consume: Compared to Quarkus, Spring Boot requires more time for booting and the OS loading all the services.
  • Require More Memory: Spring Boot projects need more memory. The bare minimum is about 72M total memory on the simplest application.
  • Highly Dependent on Starter Modules: Dependency on starter modules and lots of other dependencies negatively affect application performance.

Quarkus vs Spring Boot Comparison

ComparisonQuarkusSpring Boot
Framework typeIt is a modern cloud-native framework.It is a well-established framework.
Data persistenceUses familiar frameworks such as Hibernate – more innovativeBased on Spring Data abstraction – a more mature
SpeedFast boot timesSlower boot times than Quarkus
Memory consumptionLower memory consumption on boot and under heavy loadHigher memory consumption compared to Quarkus
MaturityThe new framework – documentation and community less active than Spring BootMuch more mature, open-source, and feature-rich. Excellent documentation and community support


In conclusion, both Spring Boot and Quarkus are excellent choices for building microservices.

However, Quarkus has some advantages over Spring Boot in terms of speed and resource usage. If you’re looking for a fast and lightweight framework, Quarkus is a great choice. But, if you want a more feature-rich framework, Spring Boot is a better choice.
