Blazor Highlighter is a free Chrome extension tailored for developers and technologists working with Microsoft's Blazor framework. This tool enhances the development process by highlighting webpage elements that utilize custom attributes generated during Blazor's rendering. By scanning the current HTML structure, it identifies specific patterns and attributes, applying distinctive visual markers to make these elements easily recognizable.

The extension serves multiple purposes, including debugging Blazor components in live environments, reverse engineering existing applications, and aiding in educational pursuits regarding Blazor's output structure. Its intuitive visual overlays allow users to quickly discern which parts of a webpage are rendered by Blazor, significantly improving the analysis and understanding of Blazor-based applications without the need for extensive manual inspection.
