View Rendered Source is a lightweight Chrome Extension that shows you how the browser has constructed (rendered) a page's original HTML into a functioning DOM, including modifications made by JavaScript.

In modern web development, HTML is no longer a static file that is built once and saved. HTML pages are no longer static text files but dynamic applications that are built with JavaScript and other client-side technologies.

Because this is a modern approach to web development, the data that is sent by the server can be completely different from the data that is displayed on the page. This makes it difficult to understand how the page is built and how it is interpreted by the browser. This is where View Rendered Source comes in. With this extension, you can view the raw HTML that the browser is rendering on the page.
