About WhatCMS.org

What We Do

WhatCMS.org is a free online service that helps you discover what Content Management System (CMS) powers any website. Our advanced detection algorithms analyze websites to identify the CMS platform, frameworks, and technologies they're built with.

Our Mission

To provide the most accurate and comprehensive CMS detection service, helping developers, marketers, and business owners make informed decisions about web technologies.

Why We Built This

Understanding what CMS a website uses can be valuable for many reasons:

• Developers can learn from successful websites and understand what technologies are being used
• Marketers can identify potential clients using specific platforms
• Security Researchers can assess website technologies for vulnerability analysis
• Business Owners can make informed decisions about which CMS to choose

How It Works

Our detection engine uses multiple techniques to identify CMS platforms:

• Pattern matching in HTML source code
• HTTP header analysis
• Cookie and session detection
• JavaScript library identification
• CSS framework detection
