FlyCache on Flywheel

Updated on December 2nd, 2022

Caching makes sites load super fast by saving snapshots of pages instead of dynamically building them from the server each time a visitor views the page.

FlyCache is Flywheel’s proprietary caching engine, specifically designed to make WordPress sites fly! It includes intelligent exclusions for popular WordPress plugins and supports e-commerce and membership sites.

What gets cached?

FlyCache features full-page caching, which means it saves the HTML of your pages along with any assets, like images CSS, and JavaScript.

Intelligent Exclusions

While caching is great, not everything on a site should be cached. For example, if you are running a store on your site, each user will need their own individual cart. Because of this, we have special rules in place to help your site load fast while still respecting the needs of the plugins on your site.


This means that we are not caching pages like cart, my-account, login, checkout, and many others in a variety of different languages.

For a complete list of default exclusions, please visit this page.

Smart Refresh

Smart Refresh is a new feature that we are rolling out to sites on our Flywheel Cloud Platform, that ensures your visitors will see the most recent content on your site.
If you make changes to your pages or posts, we will automatically clear them from the cache leaving the rest of your site’s cache intact and loading fast.

You can find more on Smart Refresh here.

How long do we cache content and files?
