Upgrading to Craft Pro
Craft’s Pro edition offers several benefits over the Solo edition, including unlimited user accounts, enhanced content previewing, and more.
It costs $399 (USD) per Craft installation, and a single license can be run across multiple development, staging, and production environments.
To check which edition you’re currently running, look for the edition badge in the control panel footer:
Click the “Upgrade to Craft Pro” link. That will take you to the Plugin Store → Upgrade Craft CMS page, which will list the two editions, and a “Buy now” button under “Pro”.
If Craft detects that it’s running in a development environment, you’ll also have the option to try Craft Pro for free.
Once you’ve upgraded, you will immediately be able to start taking advantage of the Pro-exclusive features.
