Show HN: Use Google Sheets to do realtime feature flagging (github.com)

Feature flags are useful tools to manage rollouts, perform experimentation, and much more. There's lots of companies doing serious stuff in this space, eg LaunchDarkly, Split, Optimizely, etc; two of my previous employers rolled their own experimentation platforms with tons of staffing.

However, I needed something way simpler and ideally free. So -- why not use Google Sheets as the backend? You can control who has access to read/edit flag values, there's audit history, it's incredibly simple to use. I intend to use this in production for a while, there's almost certainly a scale at which it won't make sense, but that'll be a problem for a different time.
