Alright, no beating around the bush here – I’m just gonna tell it like it is. This plugin does exactly what it says on the tin: it makes static HTML, CSS, and JS copies of your site. But don’t expect any fancy stuff like HTML minification, deferred JS, critical CSS, or any of those bells and whistles you usually see in other WordPress caching plugins. You also won’t find options to ditch emojis or compress scripts.
So, does it actually work? Yep! I tested it on one of my sites, and I easily hit an ‘A’ score on GTmetrix just by using Jetpack CDN and Cloudflare Proxy. Just a heads-up, though: it doesn’t do CDN integration. This plugin is super simple, and it’s definitely made for folks who aren’t coders or developers. So, keep your expectations in check.
If you’re just a casual blogger, this cache plugin is a solid pick – just remember to exclude any pages with online forms. But if you’re a developer like me, you’re probably better off with a different plugin that gives you more control.
Have been testing the plugin for a while. I liked the idea of a simple page caching plugin. But… I do expect that emptying cache is really working. After having some minor changes, I empty the cache. Logout as an admin, and expect the site to work normal. Often it doesn’t. It shows the menu as a long vertical list of items. The only way to get rid of it, is to disable the cache. I decided not to enable it anymore, until this is solved. I mean, even LiteSpeed (a complicated plug-in) doesn’t have issues like this.
PS: the theme I’m using it on, is the Greenshift FSE theme.
Disclaimer: I do work for StellarWP. BUT, this plugin did speed up multiple sites I’ve installed it on, including my personal site devin.org
I suggest it for a “solid” page caching solution
