An online tool for testing startup hypotheses. For example, the web counterpart of Microsoft Access?

Question

Database

It is necessary to quickly test several startup hypotheses without falling into a serious development. And let the prototype be bad in terms of performance, scaling or something else, it must be possible to weaken it in a few hours.
20 years ago, there was such a thing as Microsoft Access, which allowed you to weaken a prototype of a certain database on your knee in one evening and draw molds. Who can advise any frivolous tools that do something similar, but on the web?
