Jotai

A primitive and flexible state management library for React that uses an atomic model to eliminate unnecessary re-renders.

Jotai scales from simple useState replacements to complex enterprise architectures by using an atom-based approach. It solves the React context loss of isolation problem by splitting state into independent units (atoms) that reside within a single store. This architecture ensures that updating a single value only triggers updates in subscribed components, preventing the global re-render cascades common in Redux or large Context providers. With a 2KB footprint and zero dependencies, it provides a minimal API (useAtom) that integrates seamlessly with Suspense, Transitions, and Next.js.
