About LaunchDarkly
LaunchDarkly is a commercial platform for feature management. It lets teams switch features on and off in production and roll changes out gradually.
What it does
You wrap code paths in feature flags and decide who sees each feature, using targeting rules, segments or percentages. Progressive rollouts can increase traffic step by step, and automated rollbacks can stop a change when monitoring shows a problem. The platform also includes error monitoring, logs, traces and session replay, so you can see the effect of a change in one place.
