FormKit is an all-in-one form-authoring framework with input scaffolding (labels, help text, etc.), validation, form UI & styling, error handling, generation, a11y, i18n, and more!

Forms are everywhere, yet surprisingly tedious to author — well, not anymore. FormKit provides a powerful and flexible API to developers that makes complex form creation a breeze.

Ridiculously easy validation out-of-the-box to handle 95% of use-cases. Help text, validation rules, and validation messages are simple props. Need more? You can add custom validation rules too.

FormKit can handle the most demanding forms — wizards, multi-step, deeply nested repeating groups, and more.

Extend FormKit's functionality or reuse custom inputs, validation rules and messages across projects by tapping into the plugin system. Make your plugin open source to share with others!

Generate an entire form from a JSON-compatible schema. Schema allows you to render complex forms from JSON with conditional rendering, logic, dynamic data, groups, wrappers, HTML elements, and custom components.

FormKit works easily alongside your favorite UI frameworks like Bootstrap and utility-class tools like Tailwind. With numerous ways to modify classes and DOM structure, integrating FormKit plays nicely with any frontend.

FormKit is made for all! Thanks to the FormKit community, FormKit ships with support for many languages. Don't see your language? Contribute one with our locale builder.
