SSR Differ DevTools is a free Chrome add-on developed by Valentin Kruglikov. This add-on falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

The main purpose of SSR Differ DevTools is to help users identify the differences between server-side rendered (SSR) content and client-rendered content. This can be particularly useful for web developers and designers who want to ensure consistency and accuracy in their web applications.

To use SSR Differ DevTools, users need to follow a simple process. First, they select the request with SSR content. Then, they fill in the "Root selector" field, specifying the HTML elements between which the comparison will be made. Finally, users click "Find and compare" to initiate the comparison.
