Open Source Windows Form Builders

Formik is the world's most popular open-source form library for React and React Native. Formik takes care of the repetitive and annoying stuff, keeping track of values/errors/visited fields, orchestrating validation, and handling submission, so you don't have to. This means you spend less time wiring up state and change handlers and more time focusing on your business logic. No fancy subscriptions or observables under the hood, just plain React state and props. By staying within the core React framework and away from magic, Formik makes debugging, testing, and reasoning about your forms a breeze. If you know React, and you know a bit about forms, you know Formik! Since form state is inherently local and ephemeral, Formik does not use external state management libraries like Redux or MobX. This also makes Formik easy to adopt incrementally and keeps bundle size to a minimum.

SurveyJS Form Library is distributed as npm packages and as scripts and style sheets that you can reference on your page. You can use it in any React, Angular, Vue, Knockout, or jQuery application. React, Angular, Knockout, and Vue3 are supported natively. To communicate with the server, the libraries use JSON objects that represent form schemas (content and layout of a form) and form results (answers). You have the option to build dynamic JSON-driven forms using our free full-featured form builder demo available on the website. Alternatively, you can integrate the form builder library and create forms using a drag-and-drop UI directly within your own application. With years of development and support behind us, we've assisted hundreds of companies across various industries. With Survey, you can create nearly anything that popular cloud services offer. Furthermore, our library is fully extensible, allowing you to modify its behavior to suit your specific needs.
