Blazor WebAssembly is a new framework that was released in May 2020 that makes it possible to build client-side web applications using C# instead of using JavaScript for its frontend. The most popular web frameworks today are JavaScript based frameworks. This study aims to find out if Blazor is a viable option to use for developing web applications and if it is a well-established framework compared to JavaScript frameworks. To evaluate Blazor, a comparison is performed between Blazor and React on six criteria. The criteria are lines of code, cyclomatic complexity, state management, debugging tools, community, and libraries. To answer the criteria two applications was developed, one in the React framework and one in the Blazor framework. Besides the two applications, literature was gathered to answer the criteria. The results from the comparison showed Blazor was a Viable option to use for the development of web applications and that it has become established as a framework when taken its age in to consideration.
