OpenFeature Remote Evaluation API

The OpenFeature Remote Evaluation API (OFREP) is a new open standard API interface for feature flagging that allows the use of generic providers to connect to any feature flag management systems that supports the protocol.

Note: the standard is in its very early stages and is subject to change.

See our Bucketing API Documentation for more information on how to consume the OpenFeature Remote Evaluation API with DevCycle.
