An In-depth Analysis of Blazor and React Frameworks


Framework Blazor and React are open-source frameworks for developing interactive single-page applications.  Eventhough both front-end tools do the same functions, each has its own applications. Front-end development involves both tools based on a project’s needs. In this article, we walk you through both the front-end frameworks to help you select the right option for your business. Let’s start! 

Blazor is a user interface framework launched by Microsoft in 2018, whereas React, on the other hand, is a JavaScript library that came into being in 2013 by Facebook. It facilitates developers to create ingenious interfaces and UI components. As opposed to React, Blazor uses Razor syntax and C# rather than JavaScript. It is used to develop reusable user interfaces. Before the launch of Blazor, almost all front-end frameworks were based on JavaScript.

Understanding Blazor

As mentioned before, Blazor is an open-source framework created by Microsoft that uses HTML, CSS, and C#. It helps developers to build web user interfaces for client-side applications in .NET. The applications can run on any browser, and you don’t need any plugins or third-party add-ons. Therefore, it offers the feature of platform independence.

Further, it is interoperable with JavaScript. It makes Blazor stand out as a popular tool among the developers. It helps the app call JavaScript functions from .NET and vice versa. Also, it integrates client and server-side with C# codebase. Further, it helps developers to share advanced single-page applications and libraries.

Getting to Know React

React as said earlier, is a JavaScript-based framework for developing user interface components. It was created in 2013 by Facebook. Ever since it started its journey towards becoming the most popular UI library for building single-page applications,

Earlier before the launch of React, software coders used other frameworks such as Vue and Angular. It necessitated the need for code reworking. With the advent of React, developers were able to create reusable code components. As a result, it expedited the software development process and also, helped developers to maintain single-page applications easily.

Blazor vs React

Without further ado, we shall compare how Blazor and React is different in each other based on certain aspects such as performance, community, learning curve, language and tooling and so forth.


If we consider web application development, speed becomes paramount. Therefore, if we consider both frameworks there are pros and cons. For instance, Blazor relies on WebAssembly to execute code in the browser. Indeed, WebAssembly makes Blazor standout from other common web apps.

On the other hand, React uses virtual DOM, where it can update the user interface much faster when you incorporate changes. Due to this, you can reduce rendering times and what’s more, there is no better way to enhance user experience.

Learning Curve

Typically, ease of learning for a web development framework is a key aspect in choosing the right platform for software development. Companies offering software development services or, for instance, or a business company engaged in software development services in the UK, use the most popular frameworks that save time and optimize the app-building process.

Developers, particularly those with a web development background, will find React’s component-based approach much easier to learn. On the contrary, developers lacking experience in web development may find it difficult to use Blazor. However, those with experience in .NET and C# will prefer to use Blazor as it is less challenging compared to React.


The durability and efficacy of an open-source framework depend on the size of the community. Blazor’s community is in the stage of development while the ReactJS community is comparatively large.

For this reason, there are many resources, tools, and libraries that exist in React to help developers to create quality applications. In the case of Blazor, it is expected that the community will expand and grow as more and more software developers start adopting the language.

Language and Toolset

Blazor’s language and toolset are completely different from that of React’s. Software developers with experience in mobile and desktop application development tend to use C# and .NET with Blazor. Since React is written in JavaScript, it is used more commonly by developers.

Blazor comes with a wide variety of tools that optimize the coding process. Furthermore, it helps in bug fixing. For example, Visual Studio comes with several features to integrate with Blazor in the areas of debugging, profiling, and code completion. But on the other hand, React has libraries and tools which are mostly unknown to new developers.

Final Remarks

In short, before selecting Blazor and React, one must consider the pros and cons of each of the frameworks. Top of all, it depends on the composition of your team. Blazor is suitable for a team of .NET developers, and React is ideal for developers using JavaScript. Therefore, make a choice of the framework after considering your team and the project needs.
