The Content Revalidation Tracker plugin seamlessly connects your WordPress site with your frontend framework (such as Next.js, Nuxt, or Gatsby) to trigger revalidation via a secure API endpoint every time content changes — ensuring your site always serves the most up-to-date pages.
This plugin is ideal for headless WordPress setups that use static site generation or incremental static regeneration. Whenever you update, publish, or delete posts, pages, or taxonomies, the plugin automatically sends a secure API call to your frontend to revalidate the affected pages.
