SurveyJS
A toolkit for developers to build a custom survey or form tool inside their own app — instead of sending users off to a third-party form service, the survey lives on your own site, with your own data staying yours.

Description
Most companies handling forms and surveys just sign up for Google Forms or Typeform and accept that the data lives on someone else's servers, under someone else's terms. For a healthcare company, a bank, or anyone handling data that legally can't leave their own infrastructure, that's often not an option. SurveyJS is built for that case: instead of a hosted survey product, it's a set of building blocks a developer drops into their own application, so the form-building experience feels like a real feature of the product, and the data never has to leave the company's own servers.
SurveyJS is a suite of open-source JavaScript UI libraries (MIT-licensed Form Library, plus a drag-and-drop Survey Creator, a Dashboard for visualizing results, and a PDF Generator) for React, Angular, Vue, and plain JavaScript. It's built for accessibility (WCAG, Section 508, ARIA compliance), supports offline data collection, white-labeling with theme adapters for common design systems (Bootstrap, Material UI, shadcn/ui), 50+ language localizations, and more recently AI-assisted form generation. The core Form Library is free; the Survey Creator, Dashboard, and PDF Generator components are sold as one-time-purchase licenses with 12 months of included maintenance, an unusual model in a space dominated by per-response SaaS subscriptions.
💬 Our review
The short version: SurveyJS is the right pick specifically when you need forms or surveys embedded natively in your own product with full control over the data — a hosted tool like Typeform simply isn't an option once compliance or data residency requirements are in play.
The one-time-purchase licensing model is genuinely unusual and, for many teams, a better deal than the SaaS-subscription norm: no per-response fees, no submission caps, and the cost doesn't scale with usage the way a hosted form tool's pricing typically does. The accessibility compliance built in from the start (WCAG, Section 508, ARIA) also saves real work for regulated industries where that's a hard requirement, not a nice-to-have.
The honest caveats: this is a developer tool, not a form builder for non-technical users — someone on your team needs to integrate the library into your app's codebase, which is real engineering work compared to signing up for Typeform in five minutes. The free tier only covers the core Form Library; the visual Survey Creator and Dashboard, which most teams will actually want, require a paid license.
