MudBlazor vs Semantic UI React
Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A free C# component library that gives Blazor apps ready-made Material Design UI parts.
Open source · MIT
React components that render Semantic UI markup, so you can build interfaces with them.
The short answer
Choose MudBlazor if you need…
- .NET developers building web apps with Blazor
- Teams that want Material Design styling without writing much CSS
- Developers who want to read and modify the component source in C#
- Learners who want to follow documented examples while building a Blazor app
Choose Semantic UI React if you need…
- React developers who already use or want Semantic UI styling
- Teams building internal apps who want a consistent component set
- Developers who want components with keyboard support and accessibility in mind
- Projects that want to swap in different Semantic UI themes

What each one is
MudBlazor
MudBlazor is a set of pre-built user interface components for Blazor, Microsoft's framework for building web apps in C#. It follows Google's Material Design style, so buttons, text, and other parts look consistent without much custom work. The README says it is written entirely in C# and aims to need little CSS or JavaScript.
Semantic UI React
Semantic UI React is the official React integration for Semantic UI, a CSS-based design system. It provides ready-made React components (buttons, forms, menus and similar) that output standard Semantic UI HTML, so developers can build web interfaces without writing that markup by hand. The README says it includes no CSS itself, so you load a Semantic UI theme separately.
Best for
MudBlazor
- .NET developers building web apps with Blazor
- Teams that want Material Design styling without writing much CSS
- Developers who want to read and modify the component source in C#
- Learners who want to follow documented examples while building a Blazor app
Semantic UI React
- React developers who already use or want Semantic UI styling
- Teams building internal apps who want a consistent component set
- Developers who want components with keyboard support and accessibility in mind
- Projects that want to swap in different Semantic UI themes
Strengths
MudBlazor
- Written entirely in C#, so the code is familiar to .NET developers
- Documentation includes many examples and an interactive playground
- Has a broad automated test effort and a published quality gate, according to the README
Semantic UI React
- Official integration maintained under the Semantic-Org organization
- Includes no CSS, so any Semantic UI theme can be loaded on top
- MIT license with a large public following (about 13,000 stars)
Not ideal for
MudBlazor
- People who do not use .NET or Blazor, since it only works inside that ecosystem
- Projects that need static server rendering, which the README says is not supported
- Teams on an old, unsupported MudBlazor and .NET version, because the version table lists several older lines as ended or limited
Semantic UI React
- Projects that need a non-Semantic-UI visual style, since the components follow Semantic UI's design
- Teams wanting a fully stable release, because the latest release listed is a beta (v3.0.0-beta.2)
- Developers who need the README to document every detail; the README mostly points to external documentation
Trade-offs
MudBlazor
- Requires Blazor and a recent browser; the README notes static rendering is not supported
- Version support depends on matching .NET versions, so upgrades can involve breaking changes
- The README does not describe the full feature list, so you must check the docs for specific components
Semantic UI React
- Latest release is a beta version, so APIs may change before a stable release
- The README is brief and sends most usage details to the external documentation site
- Tied to the Semantic UI design system and its visual style
