Retool (https://retool.com) might be what you're looking for on the front-end. It's built for engineers, so it abstracts away a lot of the boiler-plate stuff (e.g. fetching data from an API, showing errors if it fails, showing a loading indicator on the button when the REST API is in progress, etc.). But you still write code for the custom bits (e.g. if you want to hide a component for certain users).
It's something we started working on a few years ago before low-code was a thing, haha. It's funny to see what you work on become a buzzword, haha. If any of you have any thoughts / feedback, please let me know! (HN, honestly, has been the main source of feedback for us as we've been working on it.)
