    Flagsmith

    Flagsmith

    Flagsmith

    Flagsmith is the bucketing engine for your experiments. Your analytics stack stays where it is. Create a multivariate flag, define variants with percentage weights, and Flagsmith splits traffic deterministically. Bucketing is calculated per identity, so a user gets the same variant on every evaluation until you change the weights. Use segments to restrict a test to the users you want to target: a plan tier, a region, or a beta cohort. And you can use the same mechanism to run beta programmes for early feedback. Flagsmith does not collect events or compute significance. Instead, send the variant name to the analytics platform you already use. Flagsmith has built in integrations for Amplitude, Mixpanel, Segment, Heap and Rudderstack, or push to your own pipeline over webhooks. One source of truth for metrics instead of two. Works the same on our cloud, your private cloud, or on-premise.
