It seems that there are no web-based equivalents to MS Access / LibreOffice Base. Not even Microsoft 365 has an equivalent.
This seems a rather curious omission.
I mean, yes, doing an online DB is going to be a little more complicated than a text document or spreadsheet, but... still. It seems like something that would be so useful that a substantial number of people would be willing to pay money for it, and possibly more money than for just the regular stuff.
Note that to get MS Access 97, you generally had to get the more-expensive Pro edition of MS Office 97... and the app by itself cost almost as much, iirc.
(I am planning to write something equivalent, eventually, but who knows how long it will be before I can get to it.)
