16 React component libraries and kits for improved UI

A React UI library, or component library, is a collection of pre-built and reusable components that enhance the development experience and accelerate time to production by providing ready-to-use design elements like tables, charts, and buttons. These libraries cater to various project requirements and include considerations such as popularity, pricing, support, community, maintenance, and licensing. This guide, updated by Joseph Mawa in March 2025, reviews 16 useful React UI libraries, including React Bootstrap, Core UI, PrimeReact, Grommet, Onsen UI, MUI, Chakra UI, Ant Design, Semantic UI React, Blueprint UI, Visx, Fluent UI, Evergreen, Mantine, Headless UI for React, and Hero UI, highlighting their unique features, pros, cons, and installation instructions. Each library offers different functionalities and customization options, and while some are more popular, others are less known but still valuable for addressing specific project needs.
