Overview
LaunchDarkly Experimentation is a sophisticated technical suite integrated into the LaunchDarkly Feature Management Platform, designed for high-velocity engineering and product teams. Unlike legacy client-side testing tools, it leverages server-side feature flags to run experiments at the edge, significantly reducing latency and flicker. The technical architecture is built on a Bayesian statistics engine, which provides more intuitive results (probability of being the best) compared to traditional Frequentist p-values, allowing for faster decision-making even with smaller sample sizes. By 2026, the platform has matured to support advanced mutual exclusion groups, enabling teams to run hundreds of overlapping tests without cross-contamination. Its primary differentiator is its 'experiment-anywhere' capability, which allows testing from UI components down to backend infrastructure configurations and machine learning model weights. The platform integrates deeply with data ecosystems like Snowflake and Databricks, ensuring that experimentation data is not siloed but part of a broader business intelligence strategy. This makes it an essential tool for organizations adopting 'Progressive Delivery' methodologies, where feature releases are not just binary toggles but measured, data-driven optimizations of the user experience.
