FluentKit is a component library for building web and app user interfaces in Blazor, a framework Microsoft uses for building apps with C# instead of JavaScript. It gives a developer ready-made pieces such as buttons, text boxes, sliders, menus, calendars, and dialogs that look and behave like Windows 11's own Fluent Design visual style, sometimes called WinUI 3. The colors, rounded corners, and visual states of every component are copied directly from Microsoft's own design files rather than guessed from screenshots, and effects like the frosted glass Mica and Acrylic backgrounds are rebuilt to match how Windows actually renders them. The library works across three kinds of Blazor apps: ones that run entirely in the browser, ones that run on a server, and ones packaged as a native mobile or desktop app through a technology called MAUI. It is built only from Razor markup and CSS, without relying on another UI framework underneath. A developer installs it as a NuGet package, links two provided stylesheets for design tokens and icons, registers a handful of services for theming and pop-up elements like tooltips and menus, wraps their app in a provided theme wrapper component, and can then start dropping in components like a styled button. The project also includes a small code generator that creates strongly typed icon names so a developer gets autocomplete and compile time checking instead of typing icon names as plain text. A live sample app demonstrates every component and is hosted online, and can also be run locally with the .NET 10 SDK. The project explicitly labels itself as alpha software, meaning its interface may still change between versions, and it is released under the MIT license, so it can be used freely, including in commercial projects.
