## What it is
SurveyJS Form Library is a free, MIT-licensed JavaScript library for rendering dynamic, JSON-driven forms, surveys, quizzes, and multi-step wizards in React, Angular, Vue, jQuery, and plain JavaScript apps. Form structure, validation, conditional logic, and theming are defined via JSON schemas, with submissions sent to any backend of your choice.

## Use cases
- build multi-step form wizards in react
- create surveys and questionnaires in a web app
- render dynamic json-driven forms
- add quizzes with scoring to a website
- collect form responses and send to my own backend
- build popup feedback surveys
- localize forms in multiple languages
- create accessible web forms with validation and conditional logic

## When to choose
- you need complex, dynamic forms or surveys across React, Angular, Vue, or vanilla JS
- you want JSON-defined form logic, validation, and conditional branching without hand-coding UI
- you need full control over data storage with any backend
- you want 20+ accessible input types, multi-page forms, and localization out of the box

## When to avoid
- you need a simple static contact form where plain HTML suffices
- you want a fully hosted form service with third-party data storage
- you need a drag-and-drop builder UI without purchasing the separate Survey Creator product
- your project is not JavaScript/web-based
