This is very cool, there's definitely a need for something that sits between the completely no-code tools and a completely DIY approach.

Your submission-based pricing is also very approachable to small-volume forms -- the industry standard is about a $25-35 minimum monthly, and even though there's often a free tier it usually includes a small subset of features.

One thing that's a blocker for me at the moment is that I can't seem to add text besides the field name to a field in the no-code tool. It's useful for providing instructions on the field, but I don't see a way to do it.

Overall this feels pretty polished, I'm impressed.
