Why the models rank Base UI — on best headless component libraries for react design systems
“Full-time MUI-backed maintenance, rapid 2025-2026 feature velocity (v1.0 with 35+ components), flexible render-prop API addressing Radix lessons, excellent accessibility, and now default in shadcn/ui for new projects; strong for greenfield custom design systems.”
Why the models rank React Aria — on best headless component libraries for react design systems
“Best overall for accessibility-critical design systems: exceptionally broad primitives, rigorous cross-device and assistive-technology behavior, internationalization, complex collections, forms, and lower-level hooks when components are insufficient. Near-tied with Radix; wins when correctness and capability breadth outweigh simplicity.”
