I am using optimizely to control which roles on my SaaS can see each feature. Its very easy to control experimentation and feature flag. Its very simple to implement and to make changes to audiences and features. We use it everyday in production, and its very easy to integrate with the Javascript library. Everything always worked fine, so we never need to call the customer support, so no feedbacks about that. Review collected by and hosted on G2.com.

At the first time, we found a little hard to understand how to register and enable the feature experimentation in our product. But past that, we didn't have any kind of issue. Review collected by and hosted on G2.com.
