It's very flexible on how to define metrics - we use our own warehouse, so we basically just feed it whatever internal business logic we already had, and Statsig helps us track metrics, check for imbalances, and cut by segments as we need. I use it as a product analyst every time we experiment, and if there is some arcane custom logic we have to run on an experiment one single time, it even outputs the tables to our warehouse so we can easily poke around in SQL.
Documentation is good, and the service staff is responsive; they have helped quickly when there are bugs to fix or stuff we didn't understand. Review collected by and hosted on G2.com.
Not much, it can be a little hard to understand the underlying logic sometimes, but that's not the fault of the platform; rather that the users should be good at documenting definitions, because Statsig does allow you to write notes/descriptions where it matters.
The few times I've personally had troubles with Statsig, they've fixed them. Review collected by and hosted on G2.com.
