Origin Story

HeroUI originated as the evolution of NextUI, rebranding and expanding its scope to better serve modern web developers with AI-friendly, accessible UI components. Founded by a team including full-stack developer Zoey Lang, HeroUI builds on the experience and community of NextUI but refines its focus on modularity, accessibility, and AI integration. The idea emerged from the need for a UI framework that is not only beautiful and performant but also deeply customizable and accessible out of the box, supporting the latest React and Tailwind CSS standards. Early traction came from strong community adoption and developer enthusiasm for its simplicity, flexibility, and continuous updates, positioning HeroUI as a living library rather than a static toolkit[5][7].
