Shovel is a free Chrome add-on developed by Sascha Hahn. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This program is designed to be a helpful tool when you need to dig through the HTML of multiple web pages to find specific technologies or booking systems.

One of the main features of Shovel is its ability to perform on-the-fly lookups of self-specified search terms. It allows users to quickly search for and identify technologies they are interested in. However, it's important to note that Shovel is not intended to replace popular extensions like BuiltWith, WhatRuns, Wappalyzer, or Datanyze. Instead, it can be used as a supplementary tool when these extensions do not provide sufficient information.

Shovel scans the outerHTML part of web pages, so it's necessary to have the technology you want to check open on the website. It does not search the content of iframes.

Overall, Shovel offers a lightweight and customizable solution for technology lookup, making it a valuable tool for users who need to quickly find specific technologies or booking systems within the HTML of web pages.
