It's a recurring monthly subscription, bringing you full access to all code generators for that time.
This subscription brings you access to an extended and growing selection of code generators.
Any unused portion of a free trial period, if offered, will be forfeited when you purchase the subscription.
The subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period.
Optional code generators for backers (saving you lots of time): Obj-C, Swift, Java, Kotlin, JavaScript, Perl, Python, Ruby, PHP.
No cancellation of the current subscription is allowed during active subscription period.
The subscription may be managed and auto-renewal may be turned off by going to your Account Settings after purchase.
Your account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal.
Code generators are a separate feature, which is connected to a payment, which is a practical way to show if you value the feature and the app itself.
So help yourself, stop deciphering unreadable example files and use this new simplified visual representation of JSON structures as object oriented models.
The subscription is allocated as monthly 1.99$ payment.
Despite the long existence of UML and best practices of software engineering you can't find any diagrams in the API documentations of Google, Facebook, Twitter and the likes.
Use JSON Designer to jump right into defining your API, without reading a single page of JSON documentation.
It is a design tool primarily, and has always been for free as my part of giving back to the developer community.
