Open source and free shadcn templates using Next.js

Neobrutalism Components is an open-source React UI library featuring a unique collection of Tailwind CSS components styled in the distinctive neobrutalism design aesthetic, characterized by bold colors, thick borders, hard shadows, and raw, unapologetic visual elements. Inspired by shadcn/ui's component architecture, this library provides pre-built components including buttons, cards, forms, inputs, navigation elements, and layout components, all designed to help developers quickly implement the bold, minimalist neobrutalism style that has gained popularity in modern web design. The project serves as both a learning resource for those interested in neobrutalism design principles and a practical component library for creating brutalist-style layouts with minimal effort. Each component showcases the characteristic features of neobrutalism including high contrast color schemes, prominent borders and outlines, deliberate lack of rounded corners, strong geometric shapes, and intentionally raw aesthetics that reject modern design polish. While the project is no longer actively maintained, it remains a valuable design resource with comprehensive documentation at neobrutalism.dev, providing developers with ready-to-use components and code examples for creating websites and applications that embrace the neobrutalist movement's philosophy of digital authenticity, functional simplicity, and visual boldness that stands out from conventional sleek designs.
