Nona

Open source remote config and feature flags you run yourself.

About Nona

Nona is an open-source remote configuration and feature flag service that you self-host with a single Docker command. Applications fetch all their parameters through one REST API call, so teams can toggle features, change mobile app behaviour or pull a kill switch instantly without redeploying. With multiple environments and official JavaScript and .NET clients, it suits teams wanting a simpler, self-owned alternative to Firebase Remote Config.
