React Stately

React Stately is a JavaScript/TypeScript library developed by Adobe, providing highly accessible and robust state management hooks for complex UI components within the React ecosystem. It is a foundational part of the Adobe React Spectrum and React Aria libraries, focusing on managing component behavior and data without dictating visual presentation. This "headless" approach allows developers to build custom UIs while leveraging battle-tested accessibility and interaction patterns. As of April 2026, the current stable version is 3.46.0. The library follows a frequent release cadence, often with monthly or bi-monthly updates, reflecting ongoing feature development and improvements, especially in coordination with React Aria Components and React Spectrum S2. Its key differentiators include a strong emphasis on WAI-ARIA standards compliance, complex collection management (lists, grids, trees), and sophisticated interaction handling, making it suitable for enterprise-grade applications requiring high accessibility and performance.
