How it works
One request tells you a lot about a website: how fast it answers, whether it is secure and cached, whether crawlers are welcome, and which frameworks, hosts and payment tools it runs on. Popularity comes from the public Tranco top-sites list.
Where does the popularity rank come from?
From the Tranco list, a research ranking of the top one million sites built from several traffic sources. Smaller sites are not ranked, which is normal for new businesses.
Why is a tool missing from the stack?
Detection reads public page code only. Back-end tools, databases behind an API and anything loaded later are invisible from outside.
