So you’re considering using Blazor for your web development project, but you’re not sure whether to go with Blazor Web App or Blazor Server. Let’s break it down for you in a simple and friendly manner, so you can make an informed decision.

Key Differences between Blazor Web App and Blazor Server

Alright, let’s start with the basics. Blazor Web App and Blazor Server both allow you to build interactive web applications using C# instead of JavaScript. However, they differ in how they handle the client-server interaction.

1. Client-side vs. Server-side Rendering

One of the main differences between Blazor Web App and Blazor Server lies in how the app is rendered on the client side. In a Blazor Web App, the entire application is downloaded to the client’s browser, and the user interacts with the app directly on their device. This means that the app can work offline and provide a faster initial load time for users.

On the other hand, Blazor Server renders the application on the server and sends only the UI updates to the client. This results in a smaller initial download size and reduced network usage. However, it also means that the app requires an active connection to the server for real-time updates, which may impact performance in low connectivity scenarios.

2. Performance and Scalability

When it comes to performance and scalability, Blazor Web App tends to be more efficient for applications that require high performance and can benefit from client-side processing power. Since the app runs directly on the client’s device, it can handle complex computations and heavy UI interactions without putting a strain on the server.

On the other hand, Blazor Server is better suited for applications that require centralized logic and real-time updates. By offloading the processing to the server, you can ensure a consistent user experience across different devices and browsers. However, this approach may result in increased server load and reduced scalability for large-scale applications.

These are just a few key differences between Blazor Web App and Blazor Server. Depending on the specific requirements of your project, you may need to consider factors like offline capabilities, network latency, and server load when choosing between the two approaches.


So, you’ve decided to dive into the world of Blazor development and are wondering whether to go with a Blazor Web App or Blazor Server. It’s a tough decision, but fear not! Let’s break down the advantages of a Blazor Web App to help you make an informed choice.
