If you mean survey/questionnaire libraries in general, the one with the most customizable UI is usually:
Best overall for UI customization
SurveyJS
- Very flexible theming and styling
- Supports custom question types and layouts
- You can fully control rendering in frameworks like React, Angular, Vue, and plain JS
- Good if you want to make the survey look like a native part of your app
Other strong options
- Form.io — highly customizable forms/UI, especially for enterprise and workflow-heavy apps
- Qualtrics — powerful, but UI customization is more limited compared with dev-first libraries
- Typeform — beautiful out of the box, but less flexible if you want deep custom UI control
- React JSON Schema Form — very customizable if you’re comfortable building the UI yourself
Quick rule of thumb
- Most customizable: SurveyJS / Form.io
- Best out-of-box design: Typeform
- Most enterprise survey features: Qualtrics
If you want, I can also compare them based on:
- design flexibility,
- pricing/open-source, or
- best choice for React/Vue/Angular.
