I have a ton of idea, but not sure how to prioritize them. Please help me to understand what is the most important for you: 1. In process evaluation for server providers. 2. Flag management system UI 3. Support tracking in all the SDKs 4. Flag sets Let me know what do you want to see 😅

*43 days until KubeCon & a bit of OpenFeature a day Nr. 1* Let's tackle the most obvious question to start this with: What is OpenFeature? A standardization of feature flagging. It's an open-source project, part of the CNCF landscape & and standardizes the look and feel of feature flags.

The OpenFeature Architecture diagram shows how OpenFeature is used for feature flagging within an app. The app in the picture owns a feature-flagging client that is used for flag evaluations. To show case OpenFeature the client in the image consists of the OpenFeature SDK and an OpenFeature provider. The SDK provides the flag evaluation API for the flag requests from the app. The provider is connected to an imaginary Flags-R-us service hosted somewhere else that stores the flag configuration.
