Frequently Asked Questions

Blazor Blueprint is the original shadcn/ui-inspired component library for Blazor, actively developed since 2025. It provides 149 pre-styled components and 38 headless primitives, offering both rapid development with beautiful defaults and full customization control. It's accessible, type-safe, built for .NET 10 and later, and backed by a growing community of contributors and teams using it in production applications.

Yes, Blazor Blueprint is free and open source under the Apache 2.0 license. You can use it in personal and commercial projects without licensing fees.

Blazor Blueprint v4 requires .NET 10 or later. It's designed to take advantage of the latest Blazor features and render modes while remaining fully compatible with earlier versions.

Yes, Blazor Blueprint is tested and compatible with all Blazor hosting models: Blazor Server, Blazor WebAssembly, and Blazor Hybrid (MAUI). Components work seamlessly across all render modes.

Blazor enables component-driven UIs with full C# type safety, eliminating entire categories of runtime errors. State management, dependency injection, authentication, and form validation all work with familiar .NET patterns, so there's no context-switching between separate JavaScript ecosystems. If your team already knows C# and .NET, Blazor lets you build rich interactive UIs without learning a new language or toolchain.

Blazor Blueprint aligns with the shadcn/ui design system, so themes from the React ecosystem work directly and developers familiar with shadcn/ui will find the API intuitive. The headless Primitives layer gives you complete styling freedom when you need it, while the pre-styled Components ship with CSS in the NuGet package — no build pipeline or CSS tooling required.

No — Blazor Blueprint is an independent implementation built from the ground up for Blazor and C#. It draws inspiration from shadcn/ui's design system and Radix UI's primitives pattern, but it contains no code from either project. Every component is written natively in C# with Blazor's component model.

No. All component styles ship inside the NuGet package via components.css, so everything works out of the box. Tailwind CSS is entirely optional — you only need it if you want to use utility classes in your own layouts and pages.

Yes — Blazor Blueprint's CSS variable system is fully compatible with shadcn/ui themes. You can copy any theme CSS from ui.shadcn.com/themes or tweakcn.com and it works immediately without any conversion.

Primitives are unstyled, headless building blocks that provide accessibility and behavior without any visual styling—you have complete control over the look and feel. Components are pre-styled versions built on top of primitives, featuring the shadcn/ui aesthetic with Tailwind CSS. Use primitives when you need full design control, or components for rapid development with beautiful defaults.

Blueprints are ready-to-use component compositions you can copy and paste directly into your Blazor apps. They combine multiple Blazor Blueprint components into common UI patterns like login forms, signup pages, and sidebars. Unlike individual components, blueprints give you a complete, styled starting point that you can customize to fit your needs. Browse all available blueprints on the Blueprints page.

Blazor Blueprint uses CSS variables with the OKLCH color space for theming. You can customize colors by modifying CSS variables in your stylesheet. The library is also compatible with shadcn/ui themes, so you can use tools like tweakcn.com to visually create and export custom themes.

Blazor Blueprint components are built with accessibility in mind. Components include semantic HTML structure, ARIA attributes (such as aria-expanded, aria-controls, and role attributes), and keyboard interaction support. Each component's documentation page lists its specific accessibility features and keyboard shortcuts. Full assistive technology testing across screen reader and browser combinations is an ongoing effort.

Absolutely. Blazor Blueprint includes enterprise-class components like Data Grid, Filter Builder, Dynamic Forms, Tree View, and Form Wizard — purpose-built for complex business applications. Every component is designed with accessibility, keyboard navigation, and type safety as first-class concerns. The library is actively used in production applications and backed by thorough documentation, an MCP server for AI-assisted development, and an open-source Apache 2.0 license with no restrictions on commercial use.
