Zustand vs Redux Toolkit: A Detailed Comparison | DevPrep

Both are excellent state management libraries. Let's compare them objectively so you can choose the right one.

Setup Comparison

Zustand

Redux Toolkit

Async Operations

Zustand — Direct async

Redux Toolkit — createAsyncThunk

Middleware

Verdict

Choose Zustand When	Choose Redux When
Small to medium apps	Large apps with complex state
You want minimal boilerplate	Team is already familiar with Redux
No Provider needed	You need RTK Query for API caching
Simple async logic	Complex async workflows
Bundle size matters	You need time-travel debugging

import { create } from "zustand";

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

// Usage
function Counter() {
  const count = useStore((s) => s.count);
  const increment = useStore((s) => s.increment);
  return <button onClick={increment}>{count}</button>;
}

import { createSlice, configureStore } from "@reduxjs/toolkit";
import { Provider, useSelector, useDispatch } from "react-redux";

const counterSlice = createSlice({
  name: "counter",
  initialState: { count: 0 },
  reducers: {
    increment: (state) => { state.count += 1; },
    decrement: (state) => { state.count -= 1; },
  },
});

const store = configureStore({ reducer: { counter: counterSlice.reducer } });

// Usage (needs Provider wrapper)
function Counter() {
  const count = useSelector((s) => s.counter.count);
  const dispatch = useDispatch();
  return <button onClick={() => dispatch(counterSlice.actions.increment())}>{count}</button>;
}

const useStore = create((set) => ({
  users: [],
  loading: false,
  fetchUsers: async () => {
    set({ loading: true });
    const users = await fetch("/api/users").then(r => r.json());
    set({ users, loading: false });
  },
}));

const fetchUsers = createAsyncThunk("users/fetch", async () => {
  return await fetch("/api/users").then(r => r.json());
});

const usersSlice = createSlice({
  name: "users",
  initialState: { users: [], loading: false },
  extraReducers: (builder) => {
    builder
      .addCase(fetchUsers.pending, (state) => { state.loading = true; })
      .addCase(fetchUsers.fulfilled, (state, action) => {
        state.users = action.payload;
        state.loading = false;
      });
  },
});

// Zustand middleware
import { devtools, persist } from "zustand/middleware";

const useStore = create(
  devtools(
    persist(
      (set) => ({ count: 0, increment: () => set(s => ({ count: s.count + 1 })) }),
      { name: "counter-store" }
    )
  )
);
