A modern UI kit for React, by the creators of Tailwind CSS
Beautifully designed, expertly crafted components and templates, built by the makers of Tailwind CSS.
Catalyst provides a professional-grade UI kit with production-ready React components (Button, Input, Table, Sidebar, Checkbox, Combobox, Radio groups, Switch, Badge, Listbox, Pagination, and more) that developers can drop directly into projects and customize, accelerating development time while maintaining design quality.
Catalyst's one-time lifetime license covers unlimited projects and scales to teams of up to 25 people, eliminating per-project licensing fees and providing long-term ROI for agencies and product teams building multiple client or internal projects.
Catalyst demonstrates how the creators of Tailwind CSS structure their own components, allowing developers and AI agents to study and emulate expert patterns for building maintainable, scalable component systems.
Catalyst is part of Tailwind Plus, which includes 500+ professionally designed UI components across marketing, application, and ecommerce categories, plus customizable site templates built with React and Next.js, enabling rapid prototyping and deployment.
Catalyst components are fully customizable and designed to integrate seamlessly with Tailwind CSS, allowing developers to gradually make components their own while using stock defaults to ship quickly, balancing speed with brand consistency.
