Easily connect your WordPress website to free optimization features from CloudFlare, including one-click options to purge cache and enable dev mode.

Current Features

This plugin was designed to load faster, be more secure, and perform much better than the official CloudFlare plugin. We focus on offering only the key features desired by most developers, while allowing some of the other CloudFlare settings to be better managed at your account over at rather than turning WordPress into a bloated control panel with every setting possible which is nearly impossible to keep up with anyways (esp. with stable/secure code).

If you wish to define the CloudFlare API key and API email address on your wp-config.php or functions.php file you can do that to avoid your clients removing that data, especially during staging site syncing, migrations, etc. Plus it will load the data faster via PHP Opcache and server/Linux RAM memory caching rather than needing database queries or Options API cache.

You can also use those defined constants to better automate server/WordPress setup using bash scripts etc.

  • one-click “dev” mode
  • one-click purge CloudFlare cache
  • automatic CloudFlare domain detection
  • real visitor IP address sent to server/WordPress
  • much lighter/faster code than “official” CloudFlare plugin
  • uses CloudFlare API version 4.0+
  • no integration with Akismet


This plugin has been designed for use on SlickStack web servers with PHP 7.2 and MySQL 5.7 to achieve best performance. All of our plugins are meant for single site WordPress installations only; for both performance and usability reasons, we highly recommend avoiding WordPress Multisite for the vast majority of projects.

Any of our WordPress plugins may also be loaded as “Must-Use” plugins by using our free Autoloader script in the mu-plugins directory.

We released this plugin in response to our managed hosting clients asking for better access to their server, and our primary goal will remain supporting that purpose. Although we are 100% open to fielding requests from the WordPress community, we kindly ask that you keep these conditions in mind, and refrain from slandering, threatening, or harassing our team members in order to get a feature added, or to otherwise get “free” support. The only place you should be contacting us is in our free Facebook group which has been setup for this purpose, or via GitHub if you are an experienced developer. Thank you!

How can I change this plugin’s settings?

Configure at /wp-admin/options-general.php?page=cloudflare

What version of the CloudFlare API is used?

It currently uses CloudFlare API version 4.

Does this plugin purge `cache everything` pages?

No, it does not support caching HTML with CloudFlare, it is only meant to purge static resources. The “cache everything” option is generally not recommended for the vast majority of dynamic websites as it causes conflicts.

Can I define the API key and email address?

Yes you can use the supported defined constants to input the API key and email address in static PHP files like wp-config.php or functions.php to avoid database queries and data loss during staging sync or migrations.

I have a suggestion, how can I let you know?

Please avoid leaving negative reviews in order to get a feature implemented. Instead, join our free Facebook group.


Didn’t work for my WordPress site

As soon as you download and Activate this plugin there immediately appear nag messages in your Dashboard suggesting a number of other plugins you should install too. The one at the top of the list appears to be essential, I think it has ‘Force SSL’ in its name (it’s deleted now so can’t be exact). Some of the other ones look more like the developer just wants you to use all of his or her plugins whether you actually need them or not, without much indication about how necessary or important or helpful they might be. So I installed this plugin and then the second one with the name that makes it look like it’s the only one I really needed anyway, but even with both plugins installed and Activated, they didn’t do anything. Mixed Content errors still appeared like they did before (and yes I Purged the Cloudflare cache and tried Development Mode). Tried to join their Facebook Group for support as they suggested but three hours later in the middle of a Wednesday in EST they still hadn’t gotten around to approving me.

I found that the ‘SSL Insecure Content Fixer’ plugin worked right away to fix Cloudflare’s Mixed Content errors. As powerful and useful as is, I wish they would make their ‘Always use HTTPS’ option in the Crypto section just work right instead of needing a plugin to fix mixed content errors. BTW Cloudflare’s own plugin was even buggier than this one, with only a blank Setup screen showing up in the Dashboard after installation and Activation. At least this plugin’s Setup page sort of worked, but the Development Mode switch apparently doesn’t communicate effectively with and turn it off and on there too, so consequently you can’t be sure the Purge Cache functionality works either.
