MellonForms — The Open-Source Youform Alternative

Create powerful, customizable forms with unlimited responses, deep logic, and total control over your data — all without usage caps or platform lock‑in.

Youform is a modern form builder with intuitive design and free forms, but MellonForms is built as a general‑purpose form platform that scales from simple lead capture to complex workflows, apps, and embedded experiences — with more extensibility, self‑hosting, and customization.
