## What it is
MobX Formkit is a reactive form state management library built on MobX observables with a UI-agnostic core. It provides declarative field definitions, extensible validation via 8 plugins, nested fields, event hooks, and bindings for React, Vue 3, Lit, Angular, Solid, and vanilla JS.

## Use cases
- manage complex form state in react with mobx
- validate forms with zod or yup schemas
- handle deeply nested form fields and arrays
- build multi-step form wizards
- share one form definition across react and vue
- bind form fields to material ui or ant design components

## When to choose
- you already use MobX and want reactive form state
- you need UI-framework-agnostic form logic reusable across renderers
- you need pluggable, mixable validation drivers (Zod, Joi, Yup, AJV, etc.)
- you need deeply nested fields, dynamic arrays, and serialization
- bundle size matters (~8KB gzip, tree-shakeable, SSR-friendly)

## When to avoid
- your project doesn't use MobX and you don't want the dependency
- you want a batteries-included React form library with built-in UI components
- you need a tiny form with minimal setup where a simpler hook-based library suffices

## Facets
