Optimizely Feature Experimentation is a full-stack experimentation and feature management platform built for product, engineering, and data teams. Run A/B and multivariate tests across web, mobile, and server-side environments from a single SDK. Feature flags, audience targeting, and real-time results all come built in. The Stats Engine supports multiple statistical methods, including sequential testing, Bayesian, and frequentist (fixed horizon), so teams can choose the approach that fits their traffic, goals, and decision-making style. Results stay valid throughout, with false discovery rate controls and outlier smoothing built in. Multi-armed bandits automatically shift traffic to winning variations. AI agents review experiments before launch, generate variations, and surface insights from results. From controlled rollouts and instant rollbacks to full-stack experimentation across every digital surface, Optimizely compresses the cycle from hypothesis to validated decision. Teams ship faster and learn with every release. * * * Seller [Optimizely](https://www.g2.com/sellers/optimizely-a5a01825-75d4-4ab9-84c1-3a421d75af81) Discussions [Optimizely Feature Experimentation Community](https://www.g2.com/products/optimizely-feature-experimentation/discuss) Solution Type All-in-One Overview by Emma Davis Show More ## Value at a Glance Averages based on real user reviews. ### Time to Implement 3 months ### Return on Investment 17 months [ View More Pricing Information ](https://www.g2.com/products/optimizely-feature-experimentation/pricing) ## Top-Rated Alternatives [ ![AB Tasty](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "AB Tasty") AB Tasty 4.4/5(416) ](https://www.g2.com/products/ab-tasty/reviews) [ ![LaunchDarkly](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "LaunchDarkly") LaunchDarkly 4.5/5(813) ](https://www.g2.com/products/launchdarkly/reviews) [ ![Statsig](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Statsig") Statsig 4.7/5(347) ](https://www.g2.com/products/statsig/reviews) [ View All Alternatives ](https://www.g2.com/products/optimizely-feature-experimentation/competitors/alternatives) ## User Insights Average based on 117 real user reviews.

Optimizely is a very powerful A/B testing platform, and their libraries are easy to integrate into our web servers. Review collected by and hosted on G2.com. What do you dislike about Optimizely Feature Experimentation? The website for managing Optimizely feature flags and experiments is a little clunky. It's very slow if there are a lot of flags set up, and the controls for rolling out flags are poorly explained. Additionally, we had to build a separate tool in order to map Optimizely's audiences to our users. Review collected by and hosted on G2.com. What problems is Optimizely Feature Experimentation solving and how is that benefiting you? It's our go-to tool for rolling out new features to a subset of users, as well as A/B testing.
