I know everyone hates Oracle, but they do have an "always free" tier of Oracle APEX, which is pretty much designed to be a low/no-code environment for CRUD apps.
funny... as nothing is ever really free with Oracle.
APEX was created to replace Forms, which really proved itself as stable technology with some apps having a 30 years lifespan now (code quality and performance aside). but APEX has not even neared Forms in terms of speed of dev. fortunately or not - Forms is so-90-ies and quite discontinued.
...should you mention APEX, then perhaps you should also note MS Access as is pretty much the same.
