SurveyJS is a family of extensible JavaScript libraries designed to help developers build a robust form management system fully integrated into their web apps. The libraries work with any backend system and are fully compatible with React, Angular, and Vue 3.

With SurveyJS, you can set up a self-hosted form management system fully integrated into your IT. It uses JSON for survey metadata and results. The drag & drop form builder features an integrated CSS-based theme editor and a GUI for conditional rules.
