Once you get the hang of the terminology and interface, it is fairly simple to manage feature flags and audiences for feature experimenting. Review collected by and hosted on G2.com. What do you dislike about Optimizely Feature Experimentation? The flow of handling large volumes of audience members is not performant via the web interface. I found when adding hundreds of records, the front end suffered. I was able to handle it all via their json interface. After discovering the json interface, it went smoothly except for that brief time on loading I had to quickly toggle that interface before the front end started crawling trying to generate elements for all my records.

It is a simple enough interface for stakeholders to manage feature experiments. It is nice that developers can set it up and then other non-technical folk can toggle or manage audiences.
