WhatCMS alternative
TL;DR. WhatCMS specializes in detecting the CMS and technologies a site runs on. SiteIntel includes tech detection too, but returns it alongside metadata, Open Graph, favicon, social links, public emails, and an optional screenshot — one call instead of stitching several APIs together.
