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 use Remotely Save plugin synced with a free tier OneDrive (sadly gdrive isn't supported) and it works very well. Maybe if you not find any alternatives good enought (most of then are a bit hard to setup and maintain) and do not want to pay the official sync plugin than this may work for you as worked for me.
