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.
Variables have been discussed, several times - see this GitHub discussion
Currently, the desired approach is to create a Marked extension, which will allow inline variable declaration (as opposed to, say, entering it into a metadata table). However, this is not a simple thing and currently the development of said extension is not a priority - I've taken a stab at it, albeit with limited success.
