Why it ranks #1

The dominant own-your-code React UI project at roughly 120k GitHub stars, with unusually broad adoption in AI-generated interfaces and a component registry used directly by major coding tools.

Here is the catch

copied components do not receive centralized package upgrades automatically
teams still have to assemble and govern their own coherent component system
heavy default adoption can make products look visually similar without deliberate customization

Does this well

developers own and can freely modify every component instead of depending on a runtime package
excellent compatibility with coding agents because its patterns are widely represented
accessible primitives and polished defaults accelerate production UI work
