Valtio is a minimal and standalone state management library for React applications. It provides a simple API for creating and managing reactive global state without the need for complex setup or boilerplate code. Valtio leverages ES6 Proxies to automatically track state changes and trigger re-renders in components that depend on the state.
Zustand is a small, fast, and scalable state management library for React applications. It provides a simple and intuitive API for managing global state in a React component tree without the need for complex setups like Redux or MobX. Zustand leverages React hooks and context to offer a lightweight yet powerful solution for state management.

Popularity
Both Valtio and Zustand are relatively popular state management libraries in the React ecosystem. Valtio gained popularity for its simplicity and ease of use, while Zustand gained popularity for its small bundle size and performance optimizations.
Size
Valtio is a small and lightweight state management library, with a minified size of around 1.5 KB. Zustand is also lightweight, with a similar size. Both libraries prioritize being minimalistic and have a small footprint in terms of size.
API and Developer Experience
Valtio provides a simple API that is inspired by Mobx. It leverages ES6 Proxies to provide a reactive and observable state. Valtio allows you to define state objects that automatically trigger re-rendering when accessed or modified. On the other hand, Zustand has a simpler API, more similar to Redux, that uses hooks to manage state. Zustand allows you to create and update state using immer, making state mutations more intuitive. Both libraries have good developer experience, but the choice depends on personal preference and familiarity with the API style.
Integration with React Ecosystem
Both Valtio and Zustand are seamlessly integrated into the React ecosystem. They work well with React components, hooks, and other libraries. They also have good TypeScript support, making it easy to work with react and type-check your applications.
Community and Documentation
Both Valtio and Zustand have active communities and are well-maintained. Valtio has a smaller community compared to Zustand but still has a good amount of support. Zustand has a more extensive documentation and examples, which makes it easier for developers to get started and find answers to their questions.
Performance
Both libraries are designed to be performant. Valtio uses ES6 Proxies for reactive updates, which can introduce some performance overhead. Zustand uses Immer under the hood, which ensures immutability and efficient state updates. In general, both libraries offer good performance, but if you have specific performance requirements, it's recommended to perform your own benchmarks and evaluations.
