In their own words
SurveyJS
SurveyJS is a set of JavaScript components for building surveys, quizzes, polls, and web forms, then storing responses and displaying results. Its free, open-source Form Library renders JSON-based forms in React, Angular, Vue, and plain JavaScript applications. It supports more than 20 question types, conditional logic, validation, multilingual forms, and right-to-left languages. Survey Creator provides a drag-and-drop designer that generates JSON schemas. Dashboard displays results through interactive charts, tables, word clouds, and aggregated statistics; PDF Generator creates editable PDF forms and exports submissions. The libraries run in a customer’s application and can connect to any backend or database. SurveyJS says it does not access, process, or store survey data; customers choose and manage their own data storage and protections. React, Angular, and Vue have native support, while jQuery uses a wrapper over the Vanilla JavaScript version. The Form Library is free, but Survey Creator, Dashboard, and PDF Generator require commercial licenses for production use. Commercial developer licenses are required for each developer working with those product APIs or implementing integrations.
