Which must-use plugins does Flywheel install?

Updated on May 1st, 2020

Flywheel installs a number of  invisible”must-use” plugins on each site hosted at Flywheel. These plugins do various things to help protect your site and optimize it to work correctly with Flywheel servers. “Must-use” plugins are always enabled, and cannot be removed. For more information about “must-use” plugins, see the official WordPress documentation.

Currently we install the following plugins:

Flywheel The Flywheel plugin installs the other MU-plugins, and does various Flywheel things like installing the admin help menu, and disabling various WordPress features incompatible with Flywheel
Limit Login Attempts Limit Login Attempts blocks an Internet address from making further attempts after a specified limit on retries is reached, making a brute-force attack difficult or impossible. For more information see the Flywheel help article: Limit Login attempts has locked me out! How do I get back in?
Disable Core Updates Completely disables the core update checking system in WordPress. The plugin prevents WordPress from checking for updates, and prevents any notifications from being displayed in the admin area. For more information on core updates with Flywheel, see the help article: How does Flywheel deal with updates to the WordPress core?
Nginx Compatibility Configures WordPress to be compatible with the Flywheel webserver – Nginx.


You still have full access to the mu-plugins directory and are able able to add “must-use” plugins of your own.

If you have questions about these plugins and what they do, don’t hesitate to contact support.
