Shovel

Helpful when you have to dig through the HTML of many pages to find technologies, booking systems, etc.

It can be used to look up self specified search terms on the fly. Shovel is not a replacement for extensions like BuiltWith, WhatRuns, Wappalyzer or Datanyze, but can be used when those deliver insufficient information.

Shovel scans the outerHTML part, so have the technology you want to check open on the website. It doesn't search the content of iframes.
