This category contains documentation topics describing the LaunchDarkly OpenFeature providers. OpenFeature is an open specification that provides a vendor-agnostic, community-driven API for feature flagging. Within OpenFeature, providers are responsible for performing flag evaluations. To learn more, reference the OpenFeature documentation. LaunchDarkly offers official OpenFeature providers for several of our SDKs, listed below. You can use these providers in your application in place of a LaunchDarkly SDK. LaunchDarkly also offers OpenFeature providers for a few of our SDKs in cases where the OpenFeature SDK does not yet have a specification released as v1.0. This is the case for Python and Ruby. In some cases, the OpenFeature community has also created OpenFeature providers compatible with LaunchDarkly SDKs. This is the case for Go and JavaScript. We welcome these community contributions but cannot officially provide support for these providers. To learn more, read about the OpenFeature Ecosystem for LaunchDarkly.
