Thanks! I glanced very briefly after a Google search, and will reply later when I have time to my own comment with a legitimate list of alternatives.
I've been following Airtable for a while and I have high hopes they continue their upward trajectory. I like where they are going, and they seem like the most likely alternative if we were to move, but Quick Base still seems to have a leg up in a lot of areas. Cross Application/Database Connections, Webhooks Support, and automated table sync from Dropbox/Box/SFTP just to name a few.
