React Aria
Adobe's library of React hooks for building accessible UI components. Implements ARIA patterns, keyboard navigation, focus management, and internationalization for 40+ component types (buttons, dialogs, menus, date pickers, etc.). Headless — no styles, pure behavior and accessibility logic. The accessibility-first alternative to Radix UI with more comprehensive ARIA pattern coverage and internationalization support from Adobe's enterprise experience.

🔒 Security
Client-side library with no network calls. Adobe's enterprise-grade security practices. Apache 2.0 and auditable. No data collection or telemetry.
⚡ Reliability
Best When
You're building a design system or component library that must meet enterprise accessibility standards (WCAG AA/AAA) and support all major screen readers and input methods.
Avoid When
You need a quick, styled component library — React Aria requires styling all components yourself; use MUI or Mantine for pre-styled accessible components.
Use Cases
- • Build fully accessible React component libraries with correct ARIA patterns, keyboard navigation, and screen reader support from Adobe's expertise
- • Implement complex accessible components (date pickers, comboboxes, color pickers) that work with all major screen readers
- • Add ARIA-compliant behavior to design system components without writing keyboard event handlers and focus management from scratch
- • Build internationalized UI with correct RTL support, locale-aware date/number formatting, and multi-language accessibility
- • Create drag-and-drop interfaces with full keyboard accessibility and screen reader announcements
Not For
- • Teams wanting pre-styled components — React Aria is headless; use React Spectrum (Adobe's styled version) for out-of-box styled components
- • Simple applications that don't require high accessibility standards — the learning curve and boilerplate may exceed benefit for basic UIs
- • Teams preferring Radix UI's simpler API for accessibility — React Aria is more comprehensive but more complex
Interface
Authentication

Agent Metadata
Known Gotchas
- ⚠ React Aria hooks return behavior props (onKeyDown, aria-* attrs) that must be spread onto DOM elements — forgetting to spread props breaks accessibility
- ⚠ useOverlay and useDialog require specific DOM structure — check documentation for required element hierarchy to avoid z-index and focus trap issues
- ⚠ React Aria Components (new API) is a higher-level abstraction than raw hooks — use Components API for new projects; raw hooks for full control
- ⚠ Date and time components require @internationalized/date package for DateValue types — not standard JS Date objects
- ⚠ I18n support requires I18nProvider wrapping your app with a locale — missing provider causes English-only behavior
- ⚠ Focus visible management (keyboard vs mouse focus styling) requires CSS :focus-visible or React Aria's FocusRing component — can't rely on :focus alone
