MobX-State-Tree (MST) is a state management library built on MobX that provides structure and common tools for managing application state. It offers a more performant and less boilerplate-heavy alternative to Redux, making it ideal for teams and applications expecting rapid code scaling. MST works exceptionally well with TypeScript, React, and React Native, supporting features like multiple stores, async actions, and extremely targeted re-renders.
