Integrate CMS detection into your applications

Getting Started

The WhatCMS.org API allows you to programmatically detect the CMS of any website. Our RESTful API is easy to integrate and returns JSON responses.

Authentication

Currently, our API is free to use without authentication. However, we recommend registering for an API key to get higher rate limits and priority support.
