I love these sorts of frameworks! Makes doing forms a lot nicer, especially the live validation.

I feel like the next evolution is automatically generating a whole form from selecting a schema in an OpenAPI spec.

In a lot of specs, the type (string, email, phone, int, etc) is present along with any constraints (min/max length). Depending on the language/OpenAPI generator, it even preserves field order. It could massively speed up a lot of the more generic forms that happen in frontend.

We also built one from scratch and used it in client-facing production applications (Angular + React Native). The biggest hurdle is that JSON schema is great at describing the shape of the form data but not a great job at describing how the form looks. We ended up creating a separate "presentation" schema which handled things like order of the form, rows/columns, widgets to use, and much more.
