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.
Rather than implementing your own you might be able to use a library like ShareDB. I think there was another one out there built on the open-sourced Google Wave code, but I don't remember the name.
