Debloat – Remove Unused CSS, Optimize JS

Reviewers say it's the best speed plugin they've tried and it fixes CSS PageSpeed issues, with a few noting delayed JS trouble and a conflict with GTranslate.

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

97 searches this plugin appeared in over the last 90 days, 20 listed. 76 left out as unrelated or noise (years, numbers, stray words). 2 of its tags aren't in the top 24 for their own search.

   My website uses Sage 10 with the Bedrock boilerplate, and for some reason I just can’t exclude some Javascript files from delayed loading. It’s a pity, because Engrish text in the plugin aside, it’s great.

   I used to pay and use Perfmatters to combine CSS, as I didn’t like the WP-Rocket implementation. But stopped using the former after finding Debloat to save some money. I’m not sure if it works as well as Perfmatters, but does do what I need it to do. It fixes all the PageSpeed insight recommendations about CSS, and my site loads very fast with it enabled for combining CSS, with WP Rocket handling everything else. I have a complex membership site with 60+ plugins and was able to get page load down to 0.9 – 1 second, even for logged-in users – and AffiliateWP still tracks cookies properly, and all else works. On the blog I also have, I got page load down to 200 – 300ms. Like other combine CSS plugins, I had to obviously add some exceptions to get some things to display properly, but that is pretty standard stuff. Anyways, this plugin is very good. I highly recommend it if you need to combine CSS.

   A bit tricky to tune it up and get it running perfectly, but one you do, it can speed up your site more than any other minifying/optimizing plugin than I’ve ever seen before. The tricky balance is figuring out which JS and CSS you can get rid of or delay without negatively impacting the operation of the site. In some cases you need to get really familiar with your web browser’s developer tools so that you can see which scripts need to run. I also appreciate that this plugin doesn’t try to do too much. Some of the optimization plugins go way overboard with features and then seem to do none of them particularly well while simultaneously spamming your WordPress dashboard with “Upgrade to Pro” messages. This one doesn’t do that at all.

   WP Rocket already does a lot to improve performance, but the bloat of WPBakery or Elementor remains. Here Debloat delivers an enormous increase in speed even with standard settings. In fact, 5 stars are not enough here. Thanks for the great plugin.

   After experimenting with so many plugins – Autoptimize, Rapid Load, Fast Velocity, Airlift, seraphinite accelerator, and many more, only Debloat plugin actually helped me with css and js minification in the right way and I noticed great results in various site speed tests. I casually searched for css minify and after scrolling a bit, I spotted Debloat plugin and it had some great convincing reviews. I went for and it actually helped with the speed. I am using it along with cache and CDN which is provided by my hosting (Lyrical Host).
