Built for real forms

From simple contact forms to complex multi-step wizards.

Declarative Validation

Define validation rules inline with your field definitions using validatorjs or custom functions. Sync and async, with per-field error messages that update reactively.

MobX Reactive

Every field state, error, and touch event is observable. Your UI reactively updates with zero extra code.

Any UI Library

Bring your own UI. Material UI, Ant Design, React Widgets, React Select, React Aria, or plain HTML — same form definition, any render.

Dynamic & Nested Fields

Deeply nested field structures, dynamic field arrays with add/remove, sortable lists, and conditional logic. Handles complex data hierarchies with MobX-powered reactivity.
