Flagsmith serves as your experimentation's bucketing solution while keeping your analytics infrastructure intact. With the ability to create multivariate flags and assign variants based on percentage distributions, Flagsmith ensures that traffic is allocated in a predictable manner. Each user is consistently assigned the same variant during evaluations until you decide to adjust the weights. You can use segments to limit tests to specific user groups, such as certain plan tiers, geographic locations, or beta testing groups. This same feature can also facilitate beta programs to gather initial user feedback. Importantly, Flagsmith does not track events or determine statistical significance. Instead, simply relay the variant name to your existing analytics platform. Flagsmith seamlessly integrates with tools like Amplitude, Mixpanel, Segment, Heap, and Rudderstack, or you can route data to your custom pipeline via webhooks. This approach allows you to maintain a single source of truth for your metrics. Whether you utilize our cloud solution, your private cloud, or an on-premise setup, Flagsmith operates consistently across all environments.
