SurveyJS is an open-source JavaScript form builder library that allows developers to create dynamic forms, multi-step form wizards, and survey applications. It supports React, Angular, and Vue.js (Vue 3), and can also be used in applications built with plain JavaScript.

Scalable open-source survey software to generate dynamic JSON-driven forms within your JavaScript application. The form builder features a drag-and-drop UI, CSS Theme Editor, and GUI for conditional logic and form branching.

Hybrid Form AI. Turn any JSON-defined form (first-class SurveyJS support) into a complete hybrid paper + digital pipeline. Multimodal LLM extraction from scanned/photographed forms with swappable providers (OpenAI, Claude, Ollama, etc.). Open-source alternative to expensive enterprise IDP tools like Rossum or FlexiCapture.

Interactive demo for hybrid-form-ai — Test the full hybrid paper + digital workflow. Configure any LLM (OpenAI, Anthropic, Ollama), upload scanned form images, provide a SurveyJS JSON definition, and see intelligent multimodal extraction in action. Built with SurveyJS + React.

Customizable JavaScript library to create interactive survey data dashboards and facilitate survey results analysis for your end-users.
