SurveyJS
Embeddable JavaScript form and survey libraries with an MIT-licensed renderer.
About
SurveyJS is a family of JavaScript libraries for building forms and surveys inside your own web app instead of on someone else's platform. The Form Library that renders surveys is MIT-licensed and free even for commercial use, with 4,904 GitHub stars and active development into October 2026. Around it sit the Survey Creator drag-and-drop builder, a PDF Generator, and an analytics Dashboard; those three are commercial, sold as perpetual per-developer licenses (Basic around $499, Pro around $899, per vendor pricing listings). Forms are defined as JSON, so they version-control cleanly, and everything runs client-side against any backend. The company behind it is Devsoft Baltic, based in Estonia.
What it can do
- MIT-licensed rendering library for React, Angular, Vue, and jQuery
- Drag-and-drop Survey Creator (commercial)
- JSON schemas that version-control like code
- PDF export and analytics dashboard add-ons
- Full data control with any backend, fully self-hosted
Setup
npm install survey-library (or the React, Angular, Vue, or jQuery package) and render a survey from a JSON schema.
Prerequisites
A JavaScript app to embed into; a commercial license key for Creator, Dashboard, or PDF Generator.
Use cases
Works with
Trust score — 8/10
Scored 8/10 (verified tier, metrics-v1). Evidence: MIT license on the Form Library and 4,904 stars read directly from the GitHub API; the commercial split (Creator/Dashboard/PDF per-developer) confirmed by the project's own skill docs and vendor pricing listings. Strengths: truly embeddable with JSON schemas, permissive license on the renderer, strong framework coverage. Docked for: (1) the builder and analytics pieces are paid, which surprises teams expecting fully free; (2) developer-oriented, so non-technical teams need engineering help. License: MIT (Form Library); commercial per-developer (Creator, Dashboard, PDF Generator).
