React State Management in 2025: Jotai, Zustand, or Signals?

React state management has come a long way — from lifting state up, to useContext, to full-blown libraries like Redux. But in 2025, the landscape is shifting. While tools like Zustand and Jotai continue to mature, newer paradigms like Signals are gaining traction — promising fine-grained reactivity, better performance, and minimal boilerplate.

So how should you manage state in modern React apps today? Let’s explore.

🧰 The Options: Redux, Zustand, Jotai, Signals

Library	Size (gzipped)	Re-render Granularity	Boilerplate	Learning Curve	React Integration
Redux Toolkit	~8kB	Medium	High	Moderate	Excellent
Zustand	~1kB	Fine-grained	Low	Low	Native
Jotai	~3kB	Atom-based (fine)	Low	Low	Native
Signals (React Canary)	~1kB	Extremely fine-grained	Very Low	Low	Experimental

🐻 Zustand: The “Minimalist Redux”

Zustand is a lightweight state library built by the creators of Zustand, SWR, and React Spring. It relies on hooks and a global store model with fine-grained selectors, so only components that use changed state will re-render.

✅ Pros:

• Dead simple API: create(), useStore()
• Great for medium/large apps
• Built-in devtools support
• Doesn’t rely on React context → fewer re-renders

🔧 Example:

import { create } from 'zustand';

const useStore = create(set => ({
  count: 0,
  increment: () => set(state => ({ count: state.count + 1 })),
}));

function Counter() {
  const count = useStore(state => state.count);
  const inc = useStore(state => state.increment);

  return <button onClick={inc}>Count: {count}</button>;
}

⚛️ Jotai: React State as Atoms

Jotai takes inspiration from Recoil but embraces simplicity and native React compatibility. It treats state as small atoms and lets you compose them with derived values and async atoms.

✅ Pros:

• Fully reactive dependency graph
• Scoped state using Providers
• Async atoms with Suspense
• Excellent TypeScript support

⚠️ Cons:

• Overhead when used in extremely large trees
• Debugging graph dependencies can be non-trivial

🔧 Example:

import { atom, useAtom } from 'jotai';

const countAtom = atom(0);

function Counter() {
  const [count, setCount] = useAtom(countAtom);
  return <button onClick={() => setCount(c => c + 1)}>Count: {count}</button>;
}

You can also create derived atoms:

const doubled = atom(get => get(countAtom) * 2);

✨ Signals: The Newcomer in React (2025+)

Inspired by Solid.js and Qwik, Signals are becoming a major topic in React discussions. They allow reactive values to exist outside the React render cycle, with component updates only when relevant state changes.

As of 2025, Signals in React are still experimental (available in the Canary build) but have huge potential:

✅ Pros:

• Blazing fast updates — no unnecessary re-renders
• Great for fine-grained reactivity in large apps
• Excellent for integrating with async flows or observables

🔧 Example (React Canary):

import { signal, useSignal } from 'react-signals';

const count = signal(0);

function Counter() {
  return <button onClick={() => count.value++}>Count: {count.value}</button>;
}

Only count-dependent components re-render. Others stay intact.

🔥 Real Use Case: Animations or dashboards with many fast-changing values

🧩 So, What Should You Use?

• 🟢 For traditional enterprise apps: Redux Toolkit still works great — especially with middleware and large teams.
• 🐻 For modern, minimal React apps: Zustand is your go-to. Simple and powerful.
• 🧬 For atom-based patterns or shared logic: Jotai excels.
• ⚡ For cutting-edge, reactive UIs: Signals may be the future — especially when React fully adopts it.

💡 Rule of thumb: Reach for Signals or Zustand first. Use Redux only if your team already lives in it or if complex middleware logic is needed.

🧱 Bonus: Hybrid Patterns

More teams are mixing local component state, Zustand for UI state, and libraries like TanStack Query or SWR for remote state (server cache).

// Typical hybrid stack
- Zustand: UI state (modals, filters)
- TanStack Query: async data
- Jotai or Signals: edge-case reactivity

🏁 Conclusion

State management in React is finally becoming less painful. You have lightweight tools that do more with less — and new reactive paradigms that break free from old rendering limitations.

In 2025, there’s no one-size-fits-all. But the trend is clear:

• Less context
• More fine-grained control
• Closer to reactive primitives

Are Signals the future? Possibly. But Zustand and Jotai are here, mature, and battle-tested. Choose what works best for your team and project scale — and don’t be afraid to mix.
