Grist – Open core alternative to Airtable and Google Sheets
"Open core", seems to mean the low level libs (useful for sure) are FOSS while the full featured apps are proprietary.  This is kind of unpleasant since it creates a tension between a natural desire to build featureful apps with the low level stuff, and not wanting to "bite the hand" that supplied grist-core.  Similar things happen with other partly-proprietary programs like ansible.Aren't there already some FOSS alternatives to google sheets?  No idea about airtable, don't even know what it is.As for simple ways to write a form app, ActiveAdmin is one of the few things I like about Rails.
