forms - Ruby on Rails customer-facing formbuilder? -

I have a client who wants to create their own questionnaire something like WooFoo (www.wufoo.com) but the app More secure and contained within

I have looked at Smarf () that provides a yam-to-form conversion, but I can use something users want to create their own form.

You can always embed Google Forms until it can be easier to change the wheel again You do not have specific usage cases, it does not cover?
