What is AB Testing Software?

A/B testing software allows businesses to compare two or more versions of a webpage, app, or marketing campaign to determine which performs better based on user behavior and key metrics. It enables marketers and product teams to run controlled experiments by splitting traffic between variants and collecting data on conversions, engagement, and other goals. The software often includes tools for test setup, audience segmentation, real-time analytics, and statistical significance calculation. Many platforms integrate with analytics and marketing tools to help optimize user experiences and drive data-driven decisions. By leveraging A/B testing software, organizations can improve conversion rates, reduce bounce rates, and enhance overall customer satisfaction.

    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.
