Akka vs RxJava: What are the differences?
Developers describe Akka as "Build powerful concurrent & distributed applications more easily". Akka is a toolkit and runtime for building highly concurrent, distributed, and resilient message-driven applications on the JVM. On the other hand, RxJava is detailed as "Reactive Extensions for the JVM". A library for composing asynchronous and event-based programs by using observable sequences for the Java VM.
Akka and RxJava are primarily classified as "Concurrency Frameworks" and "Java" tools respectively.
Akka and RxJava are both open source tools. It seems that RxJava with 39.7K GitHub stars and 6.7K forks on GitHub has more adoption than Akka with 10.1K GitHub stars and 3.04K GitHub forks.
Asana, Rainist, and ContentSquare are some of the popular companies that use Akka, whereas RxJava is used by TimeHop, SocialCops, and Poq. Akka has a broader approval, being mentioned in 76 company stacks & 57 developers stacks; compared to RxJava, which is listed in 35 company stacks and 12 developer stacks.
