MobX-State-Tree (MST) is a simple and practical state management library for React applications, inspired by Redux and MobX. It uses a tree-based data structure to manage the application state, providing a clear separation between data and logic. MST encourages immutable data modeling and makes it easy to create reactive data structures. Instead of managing individual properties, it manages entire trees of data. This makes it particularly useful for building complex applications with complex data structures.

Both Little State Machine and MobX-State-Tree are popular state management solutions in the JavaScript ecosystem. However, MobX-State-Tree has a larger community and is more widely adopted in larger-scale projects.


Little State Machine is a simple and lightweight state management library that focuses on global state management. It provides a minimalistic API and encourages managing state through actions and transitions. MobX-State-Tree, on the other hand, is a more powerful and feature-rich state management solution that is based on the MobX library. It provides a robust and scalable way to manage complex state structures with observables, actions, and computations.

Usage and Integration

Little State Machine is primarily designed for React applications and provides hooks to manage state. It can be easily integrated into a React project without much configuration. MobX-State-Tree, on the other hand, is more framework-agnostic and can be used with React, Vue, Angular, or any other JavaScript framework. It provides decorators and utilities for creating and managing state trees.

Developer Experience

Little State Machine has a straightforward and simple API, making it easy to understand and use. It requires fewer concepts to learn and is suitable for smaller projects or applications with simpler state management requirements. MobX-State-Tree, on the other hand, has a steeper learning curve due to its more advanced features and concepts. It provides a powerful toolset for managing complex state, but it may require more initial investment in understanding and learning the library.


In terms of performance, both libraries are efficient and optimized. Little State Machine is lightweight and performs well for smaller and medium-sized applications. MobX-State-Tree is known for its excellent performance, especially when dealing with large, deeply nested state structures. It utilizes efficient change tracking and selective re-rendering to ensure optimal performance.

Community and Support

Both Little State Machine and MobX-State-Tree have active communities and provide good documentation. However, MobX-State-Tree has a larger community and more extensive resources available, including a dedicated website, community forums, and official examples.
