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.
I'm surprised you haven't provided an on-site interactive version, especially as you could easily do that now at no/low cost using the superb open-source Exolve software – the creator of which is occasional visitor here, /u/wavefn. Note the FAQ at the bottom of the readme explicitly states that it's free for commercial use. The software includes a simple 'widget' function for embedding crosswords in any page, so I guess that would be useful for you. To see it in action check out any of our community crosswords (e.g. #12) and be sure to use one of the 'Reveal' buttons to see how we embed annotations with each clue. I think that's a great way for newcomers to learn how clues are constructed – which strikes me as particularly important for American publications given they don't usually have parsing/discussion sites like the British ones Fifteen Squared (all the free publications), Big Dave's (The Telegraph), and Times for the Times (The Times).
