The Metadata Viewer is a Chrome add-on developed by Lars. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This free program allows users to view the metadata of the website they are currently browsing in a visually appealing manner.

With the Metadata Viewer, users can easily access additional information about specific meta-tags on a website. This includes links to the specification, examples, the type of the meta-tag, possible values, and whether the meta-tag is deprecated or not.

To use the Metadata Viewer, simply open the Devtools in Chrome and click on the "Metadata Viewer" tab. It provides a convenient way to explore and understand the metadata of any website you are currently viewing.
