OpenFeature

Open standard and SDK for feature flagging that works with any provider

Developer ToolsFree

OpenFeature is a CNCF open standard and set of SDKs that define a vendor-neutral API for feature flagging, allowing applications to evaluate feature flags without coupling to a specific feature flag service. By coding against the OpenFeature SDK, teams can swap between LaunchDarkly, Unleash, FlagD, or custom backends by changing a provider configuration, rather than replacing SDK calls throughout their codebase. Platform teams and developers who want portability across feature flag vendors, or who are building internal feature flag tooling, adopt OpenFeature to avoid vendor lock-in in their feature flag integration layer.
