You could check Budibase, I build a simple customer portal for one of our customers with it.
Now I build a "real" project with Supabase for the backend and Vue.js + Quasar for the frontend. And that comes damn near this vision. Only a dragn'n'drop GUI editor is missing, but with the near zero reload-times of modern vue.js with Vite editing the GUI in code comes near.
There are of course several "frameworks" for Delphi, that offer "building webapps with Delphi and then compiling it to JS & Javascript, but I decided not to go into this direction, because Delphi paradigmns are no good fit for the web and I doubt I'm gonna find anyone else if I'm going to need more manpower.
