Best AB Testing Software for Linux of 2026

Flagsmith serves as the experiment bucketing engine, allowing you to maintain your existing analytics setup seamlessly. With Flagsmith, you can create a multivariate flag and assign percentage weights to different variants, enabling deterministic traffic distribution. Bucketing occurs on an individual basis, ensuring that each user consistently receives the same variant until you choose to adjust the weights. Target specific user groups for your tests using segments, whether based on subscription tiers, geographic regions, or early access beta groups. This same feature can be leveraged for beta programs to gather initial feedback. Importantly, Flagsmith does not track events or analyze significance. Instead, simply forward the variant name to your preferred analytics platform. It integrates effortlessly with tools like Amplitude, Mixpanel, Segment, Heap, and Rudderstack, or you can connect it to your own data pipeline via webhooks. This consolidates your metrics into a single source of truth. Whether you utilize our cloud services, your private cloud, or an on-premise setup, Flagsmith delivers consistent performance.
