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.
For more experienced programmers, look into Python or JavaScript libraries for a more complex application. You can deploy it on Netlify or Vercel and use a database, or look into cloud services and containerization.
For less experienced programmers, HTML/CSS/JavaScript are great languages for building a website and hosting it on Repl.it, Glitch, or GitHub pages.
