# SurveyJS Form Library

> SurveyJS Form Library (4.9k stars, v3.2.1 Oct 2026) renders forms and surveys from JSON in React, Angular, Vue or plain JavaScript and sends answers to your own backend; no SurveyJS server is needed. It is MIT-licensed. It is a developer library, not an app: no hosted form pages, response dashboard or user accounts. The drag-and-drop Survey Creator, PDF Generator and Dashboard are separate commercial products needing a per-developer licence for production, so with only the free library you write the form JSON yourself.

- Jotform: Form and survey builder, Conditional logic and branching (partial). Rendering only; PDF generation is a commercial add-on.
