GL Giovanni L. Front-End Developer Mid-Market (51-1000 emp.) 3/17/2025 "Easy to use, complicated to implement" 4/5 What do you like best about Optimizely Feature Experimentation? It is quite easy to use once it is implemented, and above all the multiple options without having to modify much of the implemented code, being able to perform A/B tests and manage variables all from the same space. Review collected by and hosted on G2.com. What do you dislike about Optimizely Feature Experimentation? The only thing I didn't like was the implementation, it's true that the team was helping us a lot, but it took us a long time to implement it, first of all to understand the implementation and above all to be able to segment perfectly. Review collected by and hosted on G2.com. What problems is Optimizely Feature Experimentation solving and how is that benefiting you? I benefit from A/B testing to be able to measure the different functionalities and designs that can affect my conversion, and to be able to control deployments easily especially when it is a big functionality that can affect several things and that anyone can do it without having to depend on the developer running it.

Review collected by and hosted on G2.com. What do you dislike about Optimizely Feature Experimentation? While Optimizely is a great tool, it lacks some essential management features. I’d love to see better tools for flag management, such as an overview of all running, paused, and stale flags, the ability to label and tag flags, custom fields for adding extra details, and insights into flags running for too long. Review collected by and hosted on G2.com. What problems is Optimizely Feature Experimentation solving and how is that benefiting you? Optimizely Feature Experimentation helps us test new features and make data-driven decisions with confidence.

I like the clarity of tracking different metrics, the tools to explain/achieve statistical significance, and the potential to connect to our data warehouse. I feel like it's hard to know exactly what I like the most at this point, as we're still early days into our adoption journey, but so far we've been setting up experiments via feature experimentation and successfully achieved conclusive results - I also like the option to apply a targeted rollout upon conclusion. We've felt well supported by the team so far too. Review collected by and hosted on G2.com. What do you dislike about Optimizely Feature Experimentation? We're struggling with the ability to match up Optimizely's event counts to the event counts on our actual front end tracking.

What do you dislike about Optimizely Feature Experimentation? Cost is a major factor right off the bat, it is just too expensive. Our budgets allow to use similar platforms comfortable that present the same use cases. More unique functionalities will help set the platform apart from the rest and help justify the spend within our leadership group. The complexity of platform uage when onboarding new inexperienced users, and intergrating this platform with the legacy systems that we have used for a long time is extremely challenging.
