Technology Lookup Examples · Example 5 of 6

A Django Site

GEThttps://api.deepinfo.com/v1/lookup/technology

The technologies on www.djangoproject.com: Nginx, Varnish, jQuery, RequireJS 2.1.15, Stripe and Plausible, but not Django itself.

Param: url
Value: https://www.djangoproject.com

Asks for the technologies on https://www.djangoproject.com, the site of the Django web framework.

Six technologies: Nginx (Web servers, Reverse proxies), Varnish (Caching), jQuery, RequireJS with the version 2.1.15 (clean_version 2.1), Stripe (Payment processors) and Plausible (Analytics). Django itself is not in the list: a framework that runs on the server leaves few traces in the page it renders, which is why the list shows what a page reveals, not the whole stack.
