OpenFeature
A CNCF open specification and multi-language SDK defining evaluation contexts, providers, hooks, and telemetry.
Why use it
Game services can change flag backends or support cloud and self-hosting without binding business code to one vendor.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
It is an abstraction, not a config service; provider intersections, caching, and failure defaults still need architecture decisions.
