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.
Check out TerriaJS made by the Geoscience Australia team. It's not the open-source analogue of AGOL like GeoNode is, but it has many of the same features and more.
This could be on the complex side, but perhaps you could check out NASA/ Caltech JPL’s MMGIS. https://github.com/NASA-AMMOS/MMGIS
