OpenFeature is a CNCF incubating open specification that standardizes vendor-neutral feature flag APIs for application code. The project homepage explains how a shared SDK surface lets teams swap flag management backends or run in-house systems without rewriting feature toggles in every service.
Platform engineers standardizing feature flag usage across microservices while retaining freedom to change flag vendors.
OpenFeature itself does not host flags; you still operate a compatible provider or in-house flag store behind the SDK.
OpenFeature defines a shared evaluation API and provider model so services can emit feature decisions consistently while backends remain swappable.
