The form framework for coding agents.

Co-located validation, self-structuring data, composability, and a compact single-component APIthat makes it easy for coding agents to reason about complex forms without boilerplate or guesswork.

One primitive. Infinite flexibility.

> *"Forms today remain fundamentally unsolved. We need a new low-level primitive to power the next generation of web applications written with AI. The FormKit Node is that primitive."*

> — Justin Schroeder, Creator of FormKit

Every ` component owns a node. Nodes automatically structure data across components at any depth — no prop-drilling, event spaghetti, or ad-hoc state stores. The result is a compact representation of form state that agents and humans can both reason about. Generated forms stay structured, editable, and consistent as your product evolves.

| Feature | |
|---|---|
| One component, every input | , , — consistent, predictable API across all inputs |
| Co-located validation | 30+ built-in rules declared inline. No separate validation schemas, no event listeners, no glue code |
| Self-structuring data | type="group" nests as objects, type="list" nests as arrays. Data shape mirrors component shape automatically |
| Schema | Generate entire forms from JSON. Conditional rendering, loops, expressions, dynamic data — all serializable |
| Theming | First-class Tailwind CSS support with the Regenesis theme, or bring your own styles |
| i18n | 30+ languages included, swap at runtime |
| Accessibility | ARIA attributes, labels, and descriptions generated automatically |
| Plugins | Extend or override anything — validation, i18n, and even input types are all plugins |
