Block Farm Editor is currently free for use on a rolling 3 month trial license.
Every 3 months, you will need to renew your license to continue using the editor. When the license expires, your website will continue running normally. You will still be able to edit content in the backoffice, but you will not be able to use the page builder to edit content on the front end. If you want to continue using the page builder, you will need to renew your license.
My target price is currently $50 a year per domain.
The license will include the following development sub domains.
dev.yourdomain.com, staging.yourdomain.com, and test.yourdomain.com. If using a .com or .org domain you will be able to also use the suffixed domains yourdomain.dev, yourdomain.stage, yourdomain.test, yourdomain.local.
