This is without a doubt the best plugin. Even for me, who doesn’t have much knowledge, it was easy to configure following the plugin’s instructions. I really managed to make my website much better after I started using debloat. I recommend!

Thank you so much for this easy to handle and amazing plug-in. As a non Code hacker & programmer it is difficult to find useless css and JavaScript. Sorry, it is not my business. But with this tool it is clear, nice and easy to work with css/js. So for me it’s a „musthave“ Plug-in !!! Thank you and please keep going !

Firstly, I want to say thank you for sharing this great plugin. It’s a relief to find something simple without lots of extra stuff. I used to like the LSCACHE plugin, but it didn’t work well for me on WP ENGINE and DIVI. This new plugin, however, does exactly what I require. I’m curious if it’s possible to adjust the «Delay JS Scripts» setting for specific pages. I believe having this feature would make this already awesome plugin even more valuable.

I have tried them all; none of them are as good as this. This is the savior to all the CSS issues especially when it comes to removing unused CSS! I hope this plugin is always updated. Something that’s even awesome is – it supports Oxygen Builder and Breakdance Builder! You must be a great person to make this available for free. God bless. I salute you! P.S. There are idiots posting bad reviews without knowing what they are even doing. Please ignore them. Cheers.
