Just to clarify, SurveyJS uses a mixed licensing model. The core Form Library is MIT-licensed, while other components (like Survey Creator, Dashboard, and PDF Generator) are commercial. All source code is available to review and fork is needed. The team behind the project is transparent that not everything is released under a permissive license.

I appreciate this approach won’t suit everyone, particularly those looking for fully permissive or copyleft solutions across the entire stack, and that’s completely fair.

As for the post, the intention was to share a tool that aligns with self-hosting principles (no data lock-in, runs on your own backend), rather than to advertise.

Thsnks!

Just to clarify, SurveyJS libraries are open-source in the sense that the full source code is publicly available and can be reviewed. Some components (like the Form Library) are released under the MIT license, while others (such as Creator, Dashboard, and PDF Generator) are distributed under a commercial license.

So it’s a mixed model: open-source with both permissive and proprietary licensing, depending on the component.

Also, my understanding is that this community focuses on self-hosted tools and software, which is what SurveyJS is, as it’s designed to be integrated and hosted within your own infrastructure.

Happy to clarify further if needed 🙂

The form builder is open-source too, all libraries are: https://github.com/surveyjs You can try it out here without registration: https://surveyjs.io/create-free-survey (it’s a demo)
