Purchasing Pro and Adding a Site License

When Is A Pro License Needed?

All of ExpressionEngine’s features are available to any sites where only a single member (no matter the role) is being used. When more than one member is needed, a Pro license is required before the site is able to be used in a production environment.

Trial use of ExpressionEngine Pro

When used in a local development environment with an approved top-level domain or hosted in an approved PaaS environment, ExpressionEngine Pro can be used freely.

Purchasing an ExpressionEngine Pro License

ExpressionEngine Pro requires a license to be installed on a publicly visible domain. You can choose from yearly or monthly billing, as well as receive a discount for additional MSM sites. If a site which was developed locally with ExpressionEngine Pro is deployed to a publicly visible site you will most likely see license error messages in your Control Panel. While not breaking the front-end of your site, an invalid license will present warning banners throughout the Control Panel that cannot be permanently dismissed

Purchase Pro from the Control Panel

To purchase an ExpressionEngine Pro license you can click on the “Purchase Pro License” link in the Control Panel (found at the bottom of the side navigation menu).
