Akka / Pekko

Akka and Pekko are toolkits for building concurrent, distributed, and resilient applications on the JVM using Scala. Akka, originally developed by Lightbend, introduced an actor model for managing concurrency, inspired by Erlang. It provides abstractions for building scalable and fault-tolerant systems. Pekko is an open-source fork of Akka, created after Akka's licensing changes, and continues to provide similar functionality under the Apache License. Both toolkits support the actor model, which simplifies the development of highly concurrent and distributed applications. They also offer additional modules for HTTP, streaming, clustering, and persistence, making them suitable for a wide range of applications, from microservices to large-scale distributed systems.
