The license key is not required for free users. Since version | PGSharp Announcement Official

The license key is not required for free users.
Since version 1.10.1, it is unnecessary to grab a license key to use the basic features of PGSharp. Thus, the trial license is also removed from our website.
If you have a license key, you're still able to use it for more features. A full feature comparison can be found on https://www.pgsharp.com/feature-comparison/.

(Note: Paid users still have higher priority when our servers are too busy.)
