Heartbeat Manager allows you to optimize your WordPress site’s performance by limiting or completely disabling the Heartbeat API calls.
The WordPress Heartbeat API uses AJAX calls (<code>admin-ajax.php</code>) to provide real-time information, such as when other users are editing a post or to show real-time notifications (like in WooCommerce). While useful, on many sites, especially E-commerce stores with high traffic, these frequent calls can put a significant strain on the server’s CPU.
This plugin allows you to granularly control this behavior via a simple settings card in Settings > Heartbeat Manager.
Key Features:
<ul>
<li>Backend Frequency Control: Increase or manage the “beat” interval while inside the WordPress Admin Dashboard.</li>
<li>Flexible Frontend Management: Choose whether to keep the Heartbeat API active on the public site or disable it completely.</li>
<li>Integrated Testing Guide: Includes a built-in step-by-step Vademecum in the sidebar to verify your settings via browser Developer Tools.</li>
<li>Lightweight & Translation Ready: Clean, lightweight code that is fully internationalized and ready for translation using the standard <code>levelnetwork-heartbeat-manager</code> text-domain.</li>
</ul>
Developed by sonofgod80 (LevelNetwork.it) to maximize site fluidity.
