Jotai vs Zustand

Jotai

• React developers who want simple shared state without heavy setup
• Teams that find a single large store too rigid and want state split into small pieces
• TypeScript projects that want typed state
• Apps that need derived values or async data fetched from state

Zustand

• React developers who want simpler shared state than Redux
• Apps that need state shared across many components without wrapping them in providers
• Projects that need to read or update state outside components via getState and setState
• Developers who want fine control over which state changes trigger re-renders

Jotai

• Minimal core API, which the README describes as about 2kb
• Works like React's useState, so the learning curve is small for basic use
• Derived and async atoms let state logic live alongside the data

Zustand

• Small, simple API based on hooks, with no providers required
• Components re-render only when the selected state they read changes
• Works with async actions and can be used outside React

Jotai

• Non-React projects, since the README only shows React usage
• People who are new to programming, since concepts like derived and async atoms take some learning
• Teams that prefer a single central store with strict conventions, since Jotai favors small independent atoms

Zustand

• Teams that require Redux's conventions, tooling, and strict structure, since the README describes zustand as un-opinionated
• Projects not using React or JavaScript, since the README focuses on JavaScript and React usage and the vanilla core is only a secondary option
• Adding state inside React Server Components, which the README explicitly advises against because it can cause bugs and privacy issues

Jotai

• The README's async examples note that they need React Suspense, which adds setup considerations
• Atom-based design differs from single-store libraries, so existing patterns may need rethinking
• The README is truncated here, so advanced features and their limits are not covered in this entry

Zustand

• The README says to set state immutably and be careful when replacing state, which takes care to get right
• Some patterns, such as fetching everything or using custom equality, can cause extra re-renders or require extra setup
• Documentation for the migration to v5 and TypeScript usage is referenced but not included in the truncated README
