This repository describes the the requirements and expectations for OpenFeature. It also contains research that was considered while defining the spec.

SDKs and client libraries
The project aims to provide a unified API and SDK for feature flag management in various technology stacks. The flag evaluation logic will not be handled in the OpenFeature SDK itself but provide a mechanism for interfacing with an external evaluation engine in a vendor agnostic way.

The OpenFeature project will include client libraries for common technology stacks including, but not limited to:
- Golang
- Java
- JavaScript/TypeScript
