Server Side Local Evaluation

Our Server Side SDKs can operate in Local Evaluation Mode. We have ported our Flag Evaluation Engine to every Server Side language SDK that we support.

Local Flag Evaluation gives you the option of running flag evaluations within your own infrastructure.

Get sub-millisecond flag evaluations within your own Infrastructure.
