Formwell

Formwell covers the least glamorous part of any product: forms. The Figma file has 180 components across inputs, selects, date pickers, file uploads, steppers and multi-step checkout flows. Each input has eight states, including disabled, read-only, loading and inline error, plus helper text and character counters wired to properties.

It's a good fit for designers who need to hand developers a complete spec for a sign-up or settings flow without inventing error states at the last minute. The kit is free for personal and commercial work, with no attribution required. The caveat: styling is deliberately neutral gray, so expect to spend an hour mapping it to your own tokens.
