Learn what Blazor is, how it works in .NET 8, and when to choose Blazor Server or WebAssembly to build modern C# web applications and MVPs for your next project.
Blazor is a free, open‑source web framework from Microsoft that lets you build interactive web apps using C# and HTML instead of JavaScript. By running .NET code either on the server or directly in the browser, Blazor enables full‑stack web development with a single language across front end and back end.
Blazor ships as part of ASP.NET Core and continues to evolve with .NET 10, bringing performance improvements, better templates, and a more polished developer experience for modern web apps.
In .NET 10, ASP.NET Core adds enhancements around Blazor templates, security, diagnostics, and performance, making it easier to build fast, resilient, and observable Blazor applications at scale.
Blazor is suitable for most modern line‑of‑business and SaaS scenarios where rich, responsive UI and long‑term maintainability matter.
Examples include:
For product teams, this single‑stack approach reduces context switching, makes hiring easier, and shortens time‑to‑market for MVPs and full‑scale platforms.
Starting a new Blazor project from scratch will require you to implement so many boilerplate features. You will end up wasting weeks of time.
Brick Starter Template for Blazor can help you save weeks of time by providing the full boilerplate implementation with 13+ ready to use features at fraction of cost.

Hosting models at a glance
| Aspect | Blazor Server | Blazor WebAssembly |
|---|---|---|
| Where code runs | On the server, over a SignalR connection | In the browser on WebAssembly |
| Initial load | Very fast, minimal download | Larger first download (runtime + app) |
| Latency | Round‑trips for UI events | Client‑side, often snappier interactions |
| Offline support | Requires connection | Can work offline/PWA scenarios |
| Security surface | Code stays on server | More logic on client, APIs must be secured |
| Ideal for | Intranet, dashboards, enterprise apps with reliable connectivity | Public‑facing apps, PWAs, lighter server load |
Blazor Server works best when you need real‑time UI, central control, and secure handling of sensitive data on the server. Blazor WebAssembly is better when you want client‑heavy experiences, offline capabilities, or to offload compute from your backend.
These concepts let you structure Blazor apps in a modular, testable way while staying fully within the .NET ecosystem.
Razor is the markup syntax that mixes C# with HTML, and it underpins both MVC/Razor Pages and Blazor components. Blazor builds on Razor to provide a component model, rendering engine, event handling, and hosting models for interactive UIs, not just server‑rendered views.
For existing ASP.NET Core teams, this means:
Blazor is not limited to traditional web apps. Using .NET MAUI and "Blazor Hybrid", you can host Razor components in native mobile and desktop shells while running them directly in the .NET process.
This hybrid model allows:
React, Angular, and Vue remain excellent choices, but Blazor offers a different value proposition for .NET‑centric teams.
| Factor | Blazor | React |
|---|---|---|
| Primary language | C# / .NET | JavaScript / TypeScript |
| Ecosystem | .NET libraries, ASP.NET Core, NuGet | NPM ecosystem, Node.js tooling |
| Code sharing | Strong sharing between backend and frontend | Possible, but usually separate stacks |
| Hosting models | Server, WebAssembly, hybrid, SSR in .NET 8 | Primarily client‑side + optional SSR via Node |
| Ideal teams | Existing .NET shops, C# developers | JS/TS‑first teams, front‑end specialists |
If your organization already invests heavily in .NET, Blazor lets you keep one language, one tooling stack (Visual Studio, Rider, VS Code), and one pool of developers across your product.
Blazor is especially compelling when:
For greenfield MVPs, Blazor lets you validate ideas quickly while keeping a codebase that scales to production‑grade multi‑tenant platforms

What is Blazor, and how does it fit into the world of web development?
Blazor is a modern web framework by Microsoft that allows developers to build interactive web applications using C# and .NET. It offers a unified approach, enabling code sharing between the client and server sides.
How does Blazor differ from traditional web development frameworks?
Unlike traditional frameworks, Blazor enables developers to write both client and server-side logic in C#, promoting code reuse and maintaining a consistent development experience.
What are the key components of Blazor that contribute to its versatility?
Blazor consists of two models—Blazor Server and Blazor WebAssembly. Blazor Server performs server-side rendering, while Blazor WebAssembly allows the execution of C# code directly in the browser.
How does Blazor enhance developer productivity in web application development?
Blazor simplifies the development process by leveraging the familiarity of C# and .NET, reducing the learning curve for developers and facilitating rapid application development.
Can Blazor be used for building both single-page applications (SPAs) and traditional multi-page applications?
Yes, Blazor supports the development of both SPAs and traditional multi-page applications, offering flexibility to cater to various project requirements.
What advantages does Blazor bring to developers in terms of code maintainability and organization?
Blazor promotes clean and organized code structures, as developers can use components to encapsulate UI elements and functionality, fostering modular and maintainable codebases.
How does Blazor contribute to a seamless development experience for .NET developers?
Blazor integrates seamlessly with the existing .NET ecosystem, allowing developers to leverage their knowledge of C# and .NET tools to build feature-rich and scalable web applications.
What are the deployment options for Blazor applications?
Blazor applications can be deployed as standalone web applications, hosted in the server environment with Blazor Server, or executed directly in the browser with Blazor WebAssembly.
How does Blazor handle data binding and communication between components?
Blazor provides robust data-binding mechanisms, enabling efficient communication between components through properties, events, and a unidirectional data flow, ensuring smooth interactions within the application.
What does the future hold for Blazor in the ever-evolving landscape of web development?
With strong backing from Microsoft and a growing community, Blazor is poised to play a significant role in the future of web development. Continuous updates, expanding libraries, and integration with emerging technologies position Blazor as a dynamic and forward-looking framework.
