Quickbase from Intuit is probably the most mature, easiest longest serving paid, hosted solution. Key is do you want to manage the tool or do you want a turn key approach. MS Power Platform, AirTable are other notables.
They’re no longer owned by Intuit and as a daily user of Quick Base I can emphatically say: avoid it. They’ve focused on cosmetic improvements over the last few years rather than any structural UX changes (or bug fixes). 5 years ago? Yea, give them a try. But no more.
