Man, given all the comments suggesting frameworks that will require you to do html/css/js it seems like no one has really read your post.

For your use case I would look at AppSmith (https://github.com/appsmithorg/appsmith) or ToolJet (https://github.com/ToolJet/ToolJet).

These are full-stack low-code frameworks, but it's easy to use them to do just the frontend and connect to a backend API you implement yourself separately.

Edit: forgot to mention that these support drag&drop for building user interfaces :)

Now this is what the OP was looking for, and it so happens that I'm going to look into these too! Thanks!

Quick question because I have no idea what I'm doing: is there any integration in either of those that you know of for one or more 3rd party auth system(s)? I don't want to write my own auth!

I'm not sure about ToolJet, but I know it's possible to use external auth systems with AppSmith.

It supports at least Firebase and Supabase. I think self-hosting Supabase + AppSmith could be a good combo for quickly hashing out prototypes or internal company apps.

Indeed. OP should have asked for "easy" or "simple to use" because "simple" means something else entirely.

Assembly language is simple.

Have you tried budibase

That looks pretty cool, I'll have to check it out :)

Thank you. At work we've been having a look at these. Decent for in house stuff.
