What we like

Works with any valid HTML form to progressively enhance validation. Infers field types and can work with Zod, Valibot, Yup schemas. Minimal integration overhead using FormData Web APIs and event delegation. Works client-side and server side using an optional Next.js server action handler or Remix action. Makes accessibility easy.
