I played around with Apps for the first time today.
I built this (alpha) tool https://github.com/UnlyEd/airtable-app-bases-compare which basically prints out a Markdown text about the base configuration (all tables, fields, options, etc.) and can then be used through another Text Diff checker tool to figure out what the differences between two bases are.
This is essential to us because we have bases that must be eventually sync (staging > production) and we were getting lost in changes until this.
I hope you’ll like it as much as we do. Keep in mind it’s still an alpha version and subject to massive changes, but it does work and might help you today.
