Fixora Heartbeat Manager is lightweight heartbeat control for WordPress: allow, limit, or disable Heartbeat where it hurts performance, so admin-ajax polling does not burn CPU on shared hosting.

Use Fixora Heartbeat Manager when you need to:
Safe defaults: dashboard limited to 60s, editor Allow, frontend disabled.
Built for the same problem people search as heartbeat control / disable heartbeat / reduce admin-ajax CPU — with modern WordPress/PHP support and no heavy framework.
