If you want the best open-source survey library for JavaScript, the usual top pick is:
SurveyJS
Why it stands out:
- Very feature-rich: multi-page surveys, conditional logic, branching, validation, custom question types, theming
- JavaScript-friendly: works with plain JS and major frameworks like React, Angular, Vue, and jQuery
- Good editor tools: includes a survey creator/designer UI
- Active project: widely used and maintained
- Flexible rendering: can be embedded in custom apps
Other solid options
Depending on your needs, you might also look at:
- Form.io — better if you need forms + backend/workflow features
- JSON Form — lightweight, JSON-schema-driven forms
- react-jsonschema-form — best if you’re already in React and want schema-based forms
- OpnForm / OhMyForm — more form-builder than survey-specific
Quick recommendation
- For a full survey system: SurveyJS
- For React + schema forms: react-jsonschema-form
- For forms tied to APIs/workflows: Form.io
