Rapid Cache is a fork of Comet Cache that focuses on new features, stability and simplicity.
If you care about the speed of your site, Rapid Cache is one of those plugins that you absolutely MUST have installed! 🤓
Rapid Cache takes a real-time snapshot (building a cache) of every Page, Post, Category, Link, etc. These snapshots are then stored (cached) intuitively, so they can be referenced later, in order to save all of that processing time that has been dragging your site down and costing you money.
The plugin uses configuration options that you select from the options panel. See: Rapid Cache -› Options in your Dashboard. Once a file has been cached, Rapid Cache uses advanced techniques that allow it to recognize when it should and should not serve a cached version of the file.
By default, Rapid Cache does not serve cached pages to users who are logged in, or to users who have left comments recently. Rapid Cache also excludes administrative pages, login pages, POST/PUT/DELETE/GET(w/ query string) requests and/or CLI processes.

Quick Tip: WordPress® can only deal with one cache plugin being activated at a time. Please uninstall any existing cache plugins that you’ve tried in the past. In other words, if you’ve installed W3 Total Cache, WP Super Cache, DB Cache Reloaded, or any other caching plugin, uninstall them all before installing Rapid Cache. One way to check, is to make sure this file:
wp-content/object-cache.php are NOT present; and if they are, delete these files BEFORE installing Rapid Cache. Those files will only be present if you have a caching plugin already installed. If you don’t see them, you’re ready to install Rapid Cache :-).
Rapid Cache is Very Easy to Install
- Upload the
/rapid-cachefolder to your
- Activate the plugin through the Plugins menu in WordPress®.
- Navigate to the Rapid Cache panel & enable it.
How will I know Rapid Cache is Working?
First of all, make sure that you’ve enabled Rapid Cache. After you activate the plugin in WordPress, go to the Rapid Cache options panel and enable caching (you can’t miss the big yellow checkbox). Then scroll to the bottom and click Save All Changes. All of the other options on that page are already pre-configured for typical usage. Skip them all for now. You can go back through all of these later and fine-tune things the way you like them.
Once Rapid Cache has been enabled, you’ll need to log out (and/or clear browser cookies). Cache files are NOT served to visitors who are logged in, and that includes you too 🙂 Cache files are NOT served to recent commenters either. If you’ve commented (or replied to a comment lately); please clear your browser cookies before testing.
To verify that Rapid Cache is working, navigate your site like a normal visitor would. Right-click on any page (choose View Source), then scroll to the very bottom of the document. At the bottom, you’ll find comments that show Rapid Cache stats and information. You should also notice that page-to-page navigation is lightning fast compared to what you experienced prior to installing Rapid Cache.
Running Rapid Cache On A WordPress® Multisite Installation
WordPress® Multisite Networking is a special consideration in WordPress®. If Rapid Cache is installed under a Multisite Network installation, it will be enabled for ALL blogs the same way. The centralized config options for Rapid Cache, can only be modified by a Super Administrator operating on the main site. Rapid Cache has internal processing routines that prevent configuration changes, including menu displays; for anyone other than a Super Administrator operating on the main site.
