SurveyJS

SurveyJS provides a set of JavaScript libraries that let developers embed fully customizable surveys and forms directly into their web applications. The core Form Library parses JSON‑defined form schemas and renders interactive, client‑side components that can collect responses and forward them to any backend database. Complementary components include a drag‑and‑drop Survey Creator that generates the JSON schema, a Dashboard for visualizing results with charts and tables, and a PDF Generator that produces editable or pre‑filled PDFs from collected data.

The toolkit is built with accessibility in mind, complying with WCAG, Section 508, and ARIA standards, and supporting keyboard navigation and screen readers. It imposes no limits on the number of forms, respondents, or submissions, and it can operate offline, storing surveys and responses locally and synchronizing when a connection is restored. Developers can extend the library with custom input fields or integrate it with frameworks such as Angular, React, or Vue 3.

SurveyJS is released under an MIT license and offers a one‑time purchase option for the Creator, Dashboard, and PDF Generator components, allowing full data ownership and white‑label deployment across industries such as insurance, healthcare, and market research.
