SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
they recently introduced change for lens (which they bought some years ago) that forces mandatory login to their systems which offers some 3rd party cloud, paid features, all that crap. Caused quite the backlash from community. Guess things aren't going good. People found way to just remove proprietary extension (which isn't part of open source project) and in recent version they introduced something that aggressively restores that extension if you removed it before. https://github.com/lensapp/lens/issues/5444
