bitplatform

bitplatform is a toolkit for building apps in Blazor, Microsoft's framework for writing web front ends in C# instead of JavaScript. The headline is bit BlazorUI: 80+ components with dark and light themes in under 400 KB. Around it sit helpers for PWAs, offline storage and browser APIs, all MIT with unlimited commercial use.

Nothing to host, it is NuGet packages and a project template. The Boilerplate template is the ambitious part: ASP.NET Core Identity, multiple languages, and one codebase targeting web, Android, iOS, Windows and macOS. Besql puts Entity Framework Core and SQLite in the browser for offline-first apps, and Butil exposes browser APIs in C#.

Teams on .NET picking a Blazor component library should put it next to MudBlazor and Microsoft's Fluent UI Blazor, and against paid suites like Telerik and Syncfusion. Every team size uses it free. Paid help runs €35 an hour (roughly $40) for code reviews, workshops, security consultation or custom features.

The catch is community size. Blazor is already a smaller world than React, and MudBlazor has a far bigger following, so expect fewer answers online when you get stuck.
