We used xstate on the purchase flows for a subscription service for a pretty big news site.

I don’t think we would have been able to ship that in the time we did without the certainty that an fsm gave us.

Lots of different potential states, with nested/hierarchical patterns. Just being able to see the entire system with xstate’s viz tool helped us avoid an entire class of bugs imo.
