Powered Cache – Caching and Optimization for WordPress – Easily Improve PageSpeed & Web Vitals Score

I think Powered Cache is the best option if you need a caching plugin that distinguishes between desktop and mobile. At least, I love it for that.

And I love it also because it writes in the .htaccess file, so, when the page is served by the cache, no lines of PHP code runs.

You can't ask more. I wish you all the best in growing this amazing plugin.

The best free caching plugin that gives you separate cache for mobile

A very nice caching plugin that encompasses both page and object cache. 

Has some advanced functionality out of the box like cache preloading and support for cookie Vary (not just cookie bypass like most plugins).

Author is responsive and active!


Great plugin

Powered Cache is one of the best cache plugins, IMO. It has all of the key features every cache plugins should have and great extra features such as object cache drop-in, varnish extension, WP-CLI commands.

I also think it has well written, secure and developer friendly code base.

One of the best!

Easy to setup and very powerful cache plugin.
Settings tabs are grouped accurately and you can find what you need in a few seconds.
Works great with Redis.

Free version has all enough features to get started with. (the most important features are in the free version - which should be appreciated, IMHO)

Idea & Wish: 
- would be great if to add disk-based object caching in the future. (for those who don't have Redis/Memcached)
- wish you will keep simplicity/liteweight approach. 
more features != better product. 
- wish you to continue supporting and improving the plugin so that it will become one of the most popular cache plugins in 1-2 years.

Simple and powerful


Powered Cache is the only cache plugin that gives excellent results on every site. Amazing job, thanks! 


Best cache plugin ever!


I've tried so many paid and free WordPress plugins to speed up my sites in the past, but I've ended in Powered Cache since it's too good!



Ability to utilize static cache generation, object cache, minification and all the other options make this plugin a one stop no-brainer solution, which was what I was looking for.



Give it a try!
