Valtio is a state management library for React applications. It provides a simple and efficient way to manage and share state across components without the need for complex setup or boilerplate code. Valtio leverages the power of ES6 Proxies to create reactive state objects that automatically update components when the state changes.
Zustand is a small yet powerful JavaScript state management library that allows you to easily manage state in your application. It provides a simple and intuitive API that allows developers to define their state and actions using a hook, and subscribe to changes in the state with minimal boilerplate.

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.
