Built with AJAX for a smooth user experience, WP Domain Checker works seamlessly with shortcodes, widgets, WooCommerce, and WHMCS, making it perfect for hosting companies, domain resellers, or anyone who wants to add domain search functionality to their site.

With the latest version, we’ve taken things further:

RDAP Integration: We’ve adopted the modern RDAP protocol, providing faster and more reliable lookup results. The plugin automatically switches to legacy WHOIS for TLDs that haven’t implemented RDAP yet.

Custom Theme Designer: Easily personalize your domain checker’s appearance. Choose your own color palette and match it perfectly with your site’s design—right from the plugin settings panel.
