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.
You can also download the code and run it locally if you don't trust someone else's machine hosting it. But like you said, all of the processing is client side so it doesn't really make a difference.
