Blazor has come a long way since 2021 and is still going strong. Blazor Web Apps can now be rendered server-side, using either static or interactive server-side rendering, as well as client-side via WebAssembly. You can also host your Blazor components in native mobile and desktop apps using Blazor Hybrid. Because of this flexibility, Blazor is now the recommended .NET web UI framework in ASP.NET Core. It can handle traditional server-side rendering (like you could do with MVC or Razor Pages) as well as fully interactive scenarios that would otherwise require JavaScript.
