Open Source Web Development Software

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.

Vue Flow Form is free, open-source and self-hosted form generator that lets you simply and quickly build custom, step-by-step forms (e.g. user registration, contact pages, feedback forms, surveys, or a quiz). Create interactive and engaging forms that you can integrate into your app or website and host on your own server.
