The Same Purpose
But Not the Same Plugin

Struggling to choose between WP-Optimize and WP Rocket? This comparison review is for you!
Here are the essential elements of these WordPress speed optimization tools compared.


WP-Optimize cache is an all-in-one web performance plugin. It has good database management and includes image optimization, but if your goal is to pass Core Web Vitals and address some PageSpeed Insights’ recommendations, you will notice significant drawbacks. There are no advanced cache and minification options.

On the other hand, WP Rocket is a solution constantly in line with the latest web performance requirements to help you improve Core Web Vitals, address Google PageSpeed recommendations, and achieve better performance scores without compromising user experience.


WP-Optimize is compatible with most tools and hosts.

Real Review from a Real User

A few words from a user who tried both plugins

I had WP Optimizer free and WP Cache (free) and a few other tweaks. I did decent rating with a 87-91% score in PageSpeed insights.

When I installed WP Rocket I did worse and was furious for about three minutes, until I started checking boxes and deactivating other useless plugins. I also added Imagify. Simple.

Now my score is 100% and an A! Page load time is some times as low as 0.5 seconds! This morning it was 1.7 seconds.

Just get it today, because if you are reading this review still its just a matter of time before you’ll have it anyway. So GO. You won’t regret it.
I cant code a single line, and I’m at the top 1% of fastest sites on the internet.

Don’t Just Take Our Word For It

Here is what our users think 

Muuuuch better than Autoptimize, W3 Total Cache etc.

Muuuuch better than Autoptimize, W3 Total Cache, etc. Used only free pagespeed optimization plugins on many websites until I got problems on a highly dynamic website. I tested WP Rocket and the site is so much faster. Also no issues so far. What makes it really awsome is the cache preload and remove render blocking CSS!

Dario Urfer

A story with WP Rocket

Before I used Autoptimize, perfmatters, WP-Optimize to optimize the performance of my little photographer website But the performance was really not there, the site was too long to load … In 2016, I used WP-Rocket, first in coupling with WP-Optimize, but finally I completely leave all these plugins to keep only WP-Rocket…WP-Rocket is constantly evolving, it has become easier and easier to use What's more, the support is always listening to us. In short I do not regret my choice. Bravo WP Rocket
