Why Medusa?

Medusa is NO more just a Website Cleaning Plugin. We will include Useful Functions and Tools for Speed, Security and more.

Is Defer Booster Code Compatible with my Theme?

Yes. We tested the plugin on several Themes. Is 99.9% Compatible with any Theme.

What is HeartBeat?

As the name indicates the heartbeat API sends continuous pulse to perform periodic tasks. All hosting companies follow a general policy of sending a warning email when the CPU utilization of the hosting server exceeds certain limit. WP Speed Grades Lite Changes HeartBeat Pulse to from 15 to 60 Seconds. This will help to reduce the server load and save hosting cost.

Why to Disable Gutenberg?

Gutenberg is a useful editor but sometimes you want to disable it. Medusa will replace it with the Classic Editor. For example, lots of WordPress users already enjoy robust page-building functionality via one of the many great plugins like Composer or Elementor. So many options, no need to feel “locked in” to using Gutenberg!

It increases the results in GT Metrix, Page Speed Insights pretty well. Better than other similar plugins.

My site went from a pagespeed insight score 68 to 48. That's pretty impressive, but not in a positive way.
