Conform
Progressive form validation
FreeLibraries & build toolingconform.guide
What it is
A form library, v1, built on the native HTML form and FormData rather than controlled React state. It validates the same schema on client and server, so forms keep working without JavaScript. Designed for React Router and Next.js server actions.
Why it earns a slot
The right pick when forms submit to a server action and you refuse to duplicate validation rules in two places. For a pure client-side SPA, React Hook Form is the simpler default.
Know before you commit
Much smaller ecosystem than RHF and tied to server-first frameworks. It is not what shadcn's Form component expects.

How Conform sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
