WhatCMS

Summary

What is WhatCMS?

WhatCMS scans thousands of artifacts—meta tags, paths, headers, session names—to determine which technologies power a website. It detects mainstream CMS like WordPress, Shopify, Drupal, plus frameworks, programming languages, hosting providers, and WordPress themes. Built for teams that need fast insight into target tech stacks.

Decision Guidance

Use WhatCMS if you're an SDR or marketing team that needs to quickly identify prospect tech stacks, or a researcher analyzing competitor technologies at scale. Ideal for outreach targeting users of specific CMS or e-commerce platforms.

Consider alternatives if you need integrated contact data and buying signals—pair with a CRM or sales intelligence tool. For occasional single-site checks, browser extensions like Wappalyzer may be more convenient.
