Overmind is a powerful state management library for building scalable applications in JavaScript and TypeScript. Overmind focuses on simplicity, predictability, and ease of testing, while still providing tons of useful features, such as time-travel debugging, hot-module reloading, and middleware support. With Overmind, developers can easily manage complex state trees and simplify their codebase through its centralized state management principle. Its modular structure also makes it easy to compose and reuse functionalities across different applications.
Both @harlem/core and Overmind have gained popularity in the JavaScript community, but Overmind has a larger user base and a more established presence.

@harlem/core is a state management library for React applications that follows a lightweight and minimalistic approach. It provides a simple yet powerful API for managing global state. Overmind, on the other hand, is a full-featured state management solution that supports React, Vue, and Angular. It offers a highly extensible and opinionated approach to managing state, with many built-in features and integrations.
Developer Experience
Both libraries provide a good developer experience. @harlem/core offers a straightforward setup and has a smaller learning curve. It focuses on simplicity and providing a clean API for state management. Overmind, on the other hand, has a more complex setup and configuration process due to its extensive feature set. It offers strong typing support and comprehensive documentation.
