IsItWP.com is a website that offers tools and resources related to WordPress. One of its features is detecting whether a website uses WordPress as its content management system (CMS). When IsItWP.com detects that a website is powered by WordPress, it applies caching to the results for up to 30 days.

Once IsItWP.com identifies a WordPress-powered website, it stores the information about the WordPress themes and plugins used on that site in its cache. This means that subsequent visits to the same website within the caching period will retrieve the information from the cache instead of rechecking the website.

You can test this functionality by providing a blank index page (without any content) instead of an actual website to demonstrate this functionality. IsItWP.com will still detect that it’s a WordPress CMS and apply caching to the results.

If you prefer to use theme detectors that check the website every time you run a check, you can try the following alternatives:

  1. WPThemeDetector: This tool detects WordPress themes and plugins used on a website and performs a fresh check each time you use it.
  2. WhatWPThemeIsThat: This online service enables you to identify WordPress themes and plugins. It also performs real-time checks and provides detailed information about the detected components.
  3. WhatCMS: While WhatCMS can detect various CMS platforms, including WordPress, it doesn’t focus solely on WordPress themes and plugins. It performs website scanning to determine the underlying CMS and other relevant details.

These alternatives offer the advantage of checking the website every time you run a check, ensuring you receive the most up-to-date information about the themes and plugins used on a WordPress site.
