The models' case: Best default for most teams: fast uncontrolled inputs, broad component-library support, strong nested and array APIs, and resolvers for Zod, Valibot, ArkType, Effect. The models' main caveat: The form type, default values, and validation schema are separate sources of truth that can drift, especially in deeply composed forms. The strongest alternative is TanStack Form — Strongest option for large or highly dynamic forms: deeply type-safe field paths, fine-grained subscriptions, composable form groups, and.
