It’s in beta right now, so details are thin, but apparently you can have them host the form, or you can get the HTML to host it yourself.
From the announcement post:
This was a part of a larger product I am working on. However it was too exciting to keep it that way. So I have decided to release it as a standalone web application.
No decision on a business model yet. At this point I am more interested in seeing the interest, getting beta users to try out things and sorting out the bugs. There are lots of remotely hosted form processors for webmasters so I am not really eager to be another one. It could become a simple web application builder for webmasters. I would only target webmasters and web designers since it would be too limiting for real programmers. OK, I already gave out too much competitive ideas to bunch of business-smart programmers. :)
What I liked about it was that you could drag and drop form elements, but only inline with each other. So you can give a non-developer the illusion of creating their own form, but you still get to keep it very uniform.
Reminds of a very simplified version of the Tibco General Interface thing we posted on last year.
