z3c.form provides an implementation for both HTML and JSON forms and according widgets. Its goal is to provide a simple API but with the ability to easily customize any data or steps.

There are currently two maintained branches:

• master with the latest changes
• 3.x without the object widget overhaul and still including the ObjectSubForm and the SubformAdapter.

Documentation on this implementation and its API can be found at https://z3cform.readthedocs.io/
