Free React form templates and blocks, compared honestly
Free React form code comes in three layers: libraries that handle state and validation (React Hook Form, TanStack Form, Conform, Formik), field components that render inputs and errors (shadcn/ui, Radix primitives), and finished form blocks you copy in (shadcn/ui’s login and signup blocks, block sites, and mebius.design’s 128 free animated forms). Most projects use a library with a set of fields, and start from a block when the form has a recognisable shape.
Form state and validation
No markup: they keep values, errors and submit state.
- React Hook Form (MIT). Uncontrolled inputs registered by name, few re-renders, resolvers for Zod, Valibot and others. The most common choice, and what shadcn/ui’s form examples use.
- TanStack Form (MIT). Type-safe field APIs with validation per field or form, sync or async, and adapters beyond React.
- Conform (MIT). Built around native form submission and server actions, so forms work before JavaScript loads.
- Formik (Apache 2.0). The older controlled-input approach; still common in existing codebases, with fewer releases now.
Field components
Inputs, labels and error messages that look like your app.
shadcn/ui (MIT) gives you inputs, selects, checkboxes, radio groups and field wrappers on Radix primitives, copied into your project. They carry no layout opinions: a form is still yours to compose. Radix primitives alone (MIT) are the unstyled base when you have your own design system.
Finished form blocks
A whole form you start from.
- shadcn/ui blocks (MIT): login and signup layouts, plain and neutral, ready for your theme.
- Block sites and marketplaces: many contact, login and pricing forms, some free and some paid. Check each block’s licence before you ship it.
- mebius.design free forms: 128 forms in React + Tailwind v4 with light and dark versions, animated with anime.js and installed from a shadcn registry. Each one is a complete, validated flow with its own visual style (dither, pixel, ASCII, Swiss and more): contact, sign-up, invoice, credit card checkout and multi-step forms among them.
The trade-off with the mebius forms: they are styled, not neutral. Each keeps its validation and keyboard behaviour, its data and handlers come in through props, and you re-skin it by editing its Tailwind classes or colour variables, but it won’t look like shadcn/ui’s defaults. Ten of them are in the open starter pack (MIT, no account needed); the rest need a free account and are free to use under the mebius.design licence.
How they fit together
Pick the library
React Hook Form with a Zod schema covers most apps; use Conform if forms must work without JavaScript.
Pick the fields
shadcn/ui’s inputs if your app already uses it, your design system’s otherwise.
Start from a block
For login, sign-up, contact, checkout or a wizard, start from a block and keep its structure and states.
Wire the submit
Validate on the server too: client validation is for the visitor, not for your data.
