FF4J vs Quarkus: What are the differences?

FF4J and Quarkus are two popular technologies used in web development. While both are used to build web applications, there are several key differences between the two.

Architecture: FF4J is a feature toggle library that focuses on feature flag management, allowing developers to enable or disable features in an application. On the other hand, Quarkus is a full-fledged Java framework that aims to provide a fast and lightweight platform for building cloud-native applications.
Supported languages: FF4J primarily supports Java, while Quarkus supports multiple languages including Java, Kotlin, Scala, and Groovy. This allows developers to have more flexibility in choosing their preferred language for web development.
Deployment: FF4J can be easily integrated into existing applications, as it is a lightweight library that can be added as a dependency. On the contrary, Quarkus is a framework that provides an end-to-end solution for building applications, including features like built-in dependency injection and native image generation, which can simplify the deployment process.
Performance: Quarkus is designed to be highly performant and can achieve fast startup times and low memory consumption. This is achieved by utilizing technologies like GraalVM and optimizing the application for running on a cloud-native environment. FF4J, being a feature toggle library, does not have similar performance optimizations built-in.
Community and ecosystem: Quarkus has a larger and more active community compared to FF4J. This means there are more resources, tutorials, and community support available for Quarkus developers. Additionally, Quarkus has a wide range of extensions and integrations with other technologies, making it easier to integrate with existing systems and libraries. FF4J, while still actively developed, may have a smaller community and fewer integrations available.
Use cases: FF4J is primarily used for feature flag management, making it suitable for applications where fine-grained control over feature enablement is required, such as A/B testing or gradual feature rollouts. Quarkus, on the other hand, is suitable for a wide range of web application development use cases, including microservices, serverless functions, and cloud-native applications.

In summary, FF4J is a feature toggle library focused on feature flag management, while Quarkus is a full-fledged Java framework for building cloud-native applications. Quarkus has a larger community, better performance optimizations, and a wider range of use cases, making it a more versatile choice for web development.

Detailed Comparison

Quarkus	FF4J
It 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.	It is an implementation of Feature Toggle pattern : Enable and disable features or your applications at runtime thanks to dedicated web console, REST API, JMX or even CLI. It handle also properties and provide generic interfaces.
