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.

    What are some alternatives to Akka and RxJava?
    Spring
    A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
    Scala
    Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.
    Erlang
    Some of Erlang's uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems.
    Kafka
    Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design.
    Spring Boot
    Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.
