LaunchDarkly
Feature management platform for flags, experimentation, and AI config control.
About
LaunchDarkly is the category-defining feature management platform, serving a claimed 42T+ daily flag evaluations with sub-200ms latency. Developers wrap code in feature flags to decouple deployment from release, then roll out progressively, target by user/device/environment context, and auto-roll back when metrics degrade. Its experimentation module runs A/B tests on the same flags, and Guarded Releases add metric-triggered safety nets.
LaunchDarkly has stayed independent while consolidating the space around it, acquiring Houseware.io to deepen warehouse-native experimentation. Its 2026 positioning centers on runtime control of AI: teams can adjust GenAI prompts, model configs, and agent behavior live without redeploys. With 35+ SDKs spanning backend, mobile, edge, and IoT, it remains the enterprise default for feature delivery, competing with open-source Unleash and Harness's flag module.
What it can do
