SurveyJS Creator is that component. Drop it into React, Angular, Vue, or vanilla JS and your users get a visual form builder with conditional logic, branching, scoring, and 20+ question types.

This is not a SaaS survey tool. It's a library you embed. Your data stays on your servers, your users never leave your app, and you control the entire experience.

The catch: the license situation is the story here. The GitHub license shows 'NOASSERTION' which means you need to read the actual terms carefully. SurveyJS uses a commercial license: the creator component requires a paid license for production use. The open source part is the survey rendering library, not the builder. Developer licenses start around $499/year.

Alternatives exist but none match the feature depth of the visual builder.

This is open core with a meaningful split:

**Free (MIT):** SurveyJS Form Library: rendering surveys, collecting responses, basic form display. You can build and render surveys programmatically for free.

**Paid:** Survey Creator (the visual drag-and-drop builder), PDF export, and analytics dashboard all require commercial licenses. Developer licenses start around $499/year per developer. There's no free tier for the builder in production.

Self-hosting is the only option; there's no SurveyJS cloud service. You host everything, which means you control your data but you also handle the infrastructure.

The math: if you're building a platform where users need to create surveys, $499/yr/dev is reasonable compared to building a form builder from scratch (months of work). If you just need to display forms, the free library handles that.
