POJO-actor: Lightweight Actor Model for Java

Turn any Plain Old Java Object into a concurrent actor. Define workflows in minimal YAML with natural conditional branching—simple enough that AI agents generate correct code on the first try.

TaskRunner.java

// Define any POJO as an actor
public class TaskRunner {
    public String execute(String command) {
        return Runtime.exec(command);
    }
}

// Use it with the actor system
IIActorRef<TaskRunner> runner =
    new IIActorRef<>("runner", new TaskRunner(), system);

// Call methods asynchronously
String result = runner.ask(r -> r.execute("deploy")).get();

Why POJO-actor?

Simple yet powerful actor model

No complex frameworks. No boilerplate. Just your Java classes with superpowers.

📦

Zero Dependencies

Use any POJO as an actor. No base classes to extend, no interfaces to implement.

⚡

Virtual Thread Native

Built for Java 21+. Each actor runs on its own virtual thread for massive concurrency.

🤖

Automaton-Based Workflows

Simple enough to get right the first time—by humans or AI agents.

🌐

Distributed Actor System

Scale across multiple nodes with location-transparent messaging. (Coming Soon)
