Subscription for Developer

Subscription for Developer

Hi,
I have been developing FileMaker application for last 10 years. I would like to become a Zoho Creator developer.

  1. What subscription should I purchase to create apps for customers? Is Zoho One good enough?
  2. If I have Zoho One subscription, can I develop applications for any number of customers and share the apps to them?
  3. Is there any help articles/blog posts regarding options for developers?
