Frequently Asked Questions about Blazor SaaS Boilerplates

What is Blazor and is it good for a SaaS?

Blazor is a .NET framework for building interactive web UIs in C# instead of JavaScript. It's a strong choice for teams already invested in .NET who want a single-language full stack for their SaaS.

Blazor Server or Blazor WebAssembly?

Blazor Server renders on the server over a live connection (fast startup, thin client); WebAssembly runs C# in the browser (works offline, heavier initial load). Many apps now use the unified Blazor render modes to mix both.

Does Blazor need JavaScript?

Mostly no — you build UI in C# and Razor. You can still interop with JavaScript libraries when needed, but day-to-day development stays in .NET.
