This is without a doubt one of the best caching plugins available. It’s the first plugin that I’ve seen work correctly with logged in users without needing to modify anything. The separate cache actually worked in all my tests. Great work!

Great Cache Plugin & Excellent Service

blpmedia February 2, 2024

I’ve worked with just about every WordPress cache plugin out there and this one ranks up there with the best of them. The performance that this plugin provides is incredible. So far it’s very stable and plays well with other plugins, too. ?? If you appreciate a developer that provides great support and not only listens to feedback, but actually provides users with results based on feedback, then support this developer. 5 stars all the way!

Completely broke the website

leviuqse January 23, 2024 1 reply

After installing the plugin the website was completely broken: it didn’t load with page cache nor with the minify, and also, once I uninstalled it all the pages started to give a 404 error completely breaking the website and having to resort to a backup.

Very good plugin
