I want a resource that lists the *product development* tech stack for a company name. I don't care what they use on their marketing website, so builtwith and (I suspect) siftery will not cover it. (Wordpress, Google Analytics are used on example.com) For instance, I dig into a Full stack developer postings list skills needed. Company A. React, Apollo, Node Company B. React, PHP and "some .Net" I'd like to filter for tech stack to save time reading postings.
Sounds like documentation hell.
