OpenFeature is an open standard for feature flag management, created to support a robust feature flag ecosystem using cloud native technologies. OpenFeature provides a unified API and SDK, and a developer-first, cloud-native implementation, with extensibility for open source and commercial offerings.

Flagsmith is proud to contribute to this initiative, and is a governance board member of this CNCF project. Our goal, and that of OpenFeature, is to recommend using OpenFeature as the default SDK interface for Flagsmith projects.

OpenFeature is being actively worked on; we encourage anyone interested Feature Flags and Open Source to get involved!
