Anyone tried airtable? It seems like it's designed specifically for this, and looks nice, but the fact that they limit number of rows per table on the free plan is a bit of a WTF.
The plan limit for free I get. However overall I think they use the records-per-base limit as their major "please don't use us for anything automated" function. You couldn't, say, build a light CRM on anything less than the enterprise version because 50k records (for pro aka $20/user/mo) just wouldn't cut it.
For those people who need database type powers for a very very small company - it's really impressive. Anyone larger...probably builds something themselves.
